# Cluemoo: every page > Cluemoo is a weekly cooperative mystery game for grandparents and grandkids, built from family stories. The index is at https://www.cluemoo.com/llms.txt. --- ## A weekly mystery your kids can only solve with Grandma or Grandpa. For grandparents and grandkids Each of them has half the clues on their own phone, and the case is built from the grandparent's own stories. Solve it together on your usual call, or on the sofa when Grandma visits. [Play the free sample](https://www.cluemoo.com/sample) [Give it as a gift](https://www.cluemoo.com/gift) - Free sample, no signup - No app or password - No ads, kids' first names only ### Calls run dry fast. This gives them something to do together. One shared mystery. A grandchild who needs Grandpa's clue. The stories come out on their own. ### Here's a real case, from both sides. Neither of you can solve it alone. Grandpa reads his clues out loud, Maya reads hers, and together you cross off suspects until one is left. Two phones. Grandpa Sol's phone shows his half of the clues; Maya's shows hers and the suspects. They read their clues to each other on the call and cross suspects off until one is left. [Try this case yourself](https://www.cluemoo.com/sample) You play both sides. It takes about 3 minutes. ### Built from your family's stories We ask the grandparent one easy question at a time. Their answers become the case. We asked “What were you doing at 17?” Grandpa Sol said “Playing trumpet in a jazz band. It was 1968.” This week's case The Case of Grandpa Sol's Missing Trumpet ### How it works 1. ### A parent sets it up Five minutes: who's playing, how old the grandkids are, and your OK as their parent. Grandpa installs nothing. 2. ### Grandpa tells a few stories We email him a short, friendly chat, one easy question at a time. His answers become the mystery. 3. ### Solve it together A new case on your family's day. On your call or at the table, each of you opens your own link, reads your clues out loud, and agrees on the answer. Every answer is something true from your family's stories, and whoever the story is about gets to tell the rest. [More about how it works](https://www.cluemoo.com/how-it-works) ### Made to fit each player Big text, read-aloud clues and puzzles that fit each player. Ages 4 to 17. - ### Grandpa who doesn't do apps No app, no account, no password. One link in an email, big text, one main button per screen. - ### Little ones who can't read yet Picture choices, a picture lock, and every clue read out loud. Grandma's half can still be harder. - ### Two grandkids, one team Brothers and sisters share a side and work it out together, each on their own link. - ### An ocean and six time zones away Each case stays open until the next one, so you play whenever your days overlap. Any call app works. Grandpa's clue Whoever took my trumpet had flour on their sleeves. Maya & Eli's clue The baker never leaves the shop on a Tuesday. ### 21 kinds of puzzle, all made for two Secret codes, split maps, logic grids, number locks, mazes where one of you has the map, shared crosswords and more. Each case has 4-6 puzzles and a quick game or two, and every puzzle is checked by computer before anyone plays it. The grandparent's stories run through all of it, so the answers are things only your family knows. ### Not another memoir book. A reason to call. | What you get | Video call | Memoir book | Cluemoo | | --- | --- | --- | --- | | Something to do together on the call | No | No | Yes | | Built from the grandparent's own stories | No | Yes | Yes | | The grandkids take part every week | Yes | No | Yes | | Made for little kids and big kids | No | No | Yes | | A printed keepsake book at the end | No | Yes | No | Plenty of families do both: a memoir for the shelf, and a mystery for Sunday. ### A year of Sundays for $1.90 a week Pay once. Nothing renews. Every week or every other week, it's the same amount of play for the price, and you get a full refund within 30 days, no questions asked. - ### 3 months $35 once $2.69 a week of play 13 weeks of mysteries - ### 6 months $59 once $2.27 a week of play 26 weeks of mysteries - Best value ### 12 months $99 once $1.90 a week of play 52 weeks of mysteries Not sure yet?

[Give it as a gift](https://www.cluemoo.com/gift) ### Questions **What is Cluemoo?** It's a cooperative mystery game for grandparents and grandkids, built from family stories. Every week or every other week, the grandparent gets half the clues and the grandchild gets the other half. They solve it together in about 30-60 minutes over FaceTime, WhatsApp, Zoom or a phone call. **Does Grandma need to download an app or remember a password?** No. It works in any phone or tablet browser. Each player gets their own link by email. Tap it and the clues open. There's no app to install, no account to create and no password to remember. **Where do the stories in the mystery come from?** From the grandparent. After setup, we email them a short chat that asks one easy question at a time, like where they grew up or a dish they're famous for. They type or speak their answers, and the first case is built from them. After each case there's one more question, so the stories keep coming. **Who writes the mysteries?** An AI model, Anthropic's Claude, drafts each case from the stories your family shares. Then every puzzle is checked by computer before anyone plays it, checking it has exactly one answer and that neither side can solve it alone. A puzzle that fails is swapped for one we've already tested. Children's data is never used to train any AI model. **How is Cluemoo different from a memoir service like Storyworth?** Memoir services email the grandparent writing prompts and print the answers as a book. Cluemoo also starts from the grandparent's stories, but turns them into a game the grandkids play with the grandparent on a call. One makes a keepsake; the other makes a weekly reason to talk. Some families do both. **Is it only for grandparents?** For now, yes. Cousins in different homes, step-families, aunts and uncles, and parents living apart are next. When two households share a game, each parent adds and consents for their own kids. **What ages is it for?** Grandkids from 4 to 17. The puzzles get harder with age: picture choices for little ones, decoders and maps from about 8, harder ciphers for teens. Reading is set separately, so a child who isn't reading yet gets pictures and every clue read out loud, and a grandparent can switch on large text. [All questions](https://www.cluemoo.com/faq) ### See it for yourself in 3 minutes. Play both halves of a real case on your own. No signup, no email. [Play the free sample](https://www.cluemoo.com/sample) --- ## The Case of Grandpa Sol's Missing Trumpet Free sample · about 3 minutes · you play both sides Grandpa Sol played trumpet in a jazz band in 1968. On Saturday he's meant to play it at Maya's school concert, but this morning the trumpet vanished from the hall closet. Grandpa has half the clues. Maya has the other half. Neither can crack it alone. **Or play it on two phones** Send Grandpa's half to someone (a grandparent is perfect), open Maya's half yourself, then call each other and solve it together. [Open Maya's half](https://cluemoo-app.vercel.app/play/demo-grandchild) --- ## How a family mystery works Cluemoo is a weekly cooperative mystery game for grandparents and grandkids, built from family stories. Each player holds half the clues on their own phone, so the grandparent and grandkids have to talk to solve it. 1. ## A parent sets it up About five minutes: who's playing, the grandkids' ages and reading levels, your family's day, and consent for your children. You can add a few family stories too, in case the grandparent is slow to reply. 2. ## The grandparent tells a few stories We email the grandparent a link to a short chat: one easy question at a time, like “Where did you grow up?” They can type or tap the microphone on the keyboard and talk. About ten minutes, and any question can be skipped. 3. ## A new case opens on your day At 8am on your family's day, every week or every other week. Each case is 4-6 puzzles that tell one chapter of the mystery, plus a quick game or two. An AI model (Anthropic's Claude) drafts it from your family's stories, and every puzzle is checked by computer before anyone plays it, so it has exactly one answer and needs both halves. 4. ## Solve it together, on any call or in the same room FaceTime, WhatsApp, Zoom or a plain phone call; or two screens at one table when you're together. Each player opens their own link and reads their clues out loud. Every puzzle is made of one of your family's stories, so each answer is something true about someone on the call, and the person whose story it is gets to tell the rest of it while you solve. Progress is saved, and each case stays open until the next one. ### How a story becomes a case Step 2, up close: one answer from the grandpa in our free sample, and the case it became. We asked “What were you doing at 17?” Grandpa Sol said “Playing trumpet in a jazz band. It was 1968.” This week's case The Case of Grandpa Sol's Missing Trumpet ### What each player sees The grandparent's link shows their half of the clues; the grandchild's link shows the other half. Neither half is enough on its own. Two phones. Grandpa Sol's phone shows his half of the clues; Maya's shows hers and the suspects. They read their clues to each other on the call and cross suspects off until one is left. ### 21 kinds of puzzle, each made for two New kinds come in as a mystery goes on, and the last puzzle is always a lock to open. - ### Secret code One of you has the secret numbers, the other has the key. Read them out to crack the code. - ### Guide me home One of you has the map. Say which way to go, and the other taps the arrows. - ### Treasure map You each have clues about where something is hidden. Put them together to find the square. - ### Whodunit Each of you has clues that rule some answers out. Share them until only one is left. - ### Invisible ink One of you has a grid and the other a card with holes: say where the holes are to find the secret. - ### Spot the difference You each have a picture that looks the same but isn't. Talk it through and tap the squares that are different. **See all 21 kinds → Show fewer** - ### What happened first? You each have clues about when things happened. Put them together to find the order. - ### The number lock You each have clues about the secret numbers. Put them together to open the lock. - ### Copy my pattern One of you sees a pattern and says it out loud. The other taps it back. - ### Who had what? You each have clues about who has what. Put them together to answer the question. - ### Picture square Each row and column has every picture once. Share your squares to find the star. - ### The balance You each see different balance scales. Put them together to work out the weights. - ### Shared crossword You each have the clues for some of the words. Solve them together, then read the circled squares. - ### Guess who You both see the same line-up. Share your clues about how they look to find the one. - ### Fix the robot One of you can see the machine, the other has the rulebook. Describe it, find the rule, and pick what to do. - ### Word builder You each have some letter tiles. Put them together to find the one word that uses them all. - ### Shopping trip One of you has the prices, the other has the wallet and the shopping list rules. - ### Catch the train One of you has the timetable, the other knows when you need to be there. Pick the train. - ### Find it in the picture One of you has a wanted poster, the other a busy picture. Describe the poster so your partner can find it and tap it. - ### Build what I see One of you sees a picture, the other builds it. Say what goes where; the builder taps a tile, then a square. - ### Match-up One of you has numbered cards, the other has their partners. Read out your cards; give each partner the number of the card it goes with. ### Ages 4 to 17 Puzzles get harder as the grandkids grow. - **Little detectives** · ages 4–7 - **Junior detectives** · ages 8–12 - **Senior detectives** · ages 13+ ### Reading is set for each player Separate from age. Each half is written for whoever reads it. - **Listener** · Not reading yet. Pictures, and every clue read out loud. - **Early reader** · Reads short, simple sentences. - **Confident reader** · Reads chapter books on their own. - **Advanced reader** · Reads anything. Most teens and adults. Anyone can turn on read-aloud, large text, or extra spacing between letters and lines. ### Questions about playing **Can Grandma and Grandpa both play?** Yes, together. Each case has one grandparent's side with one link, so Grandma and Grandpa sit side by side and read their clues from it. A separate link for a second grandparent isn't available yet. The other side is for one or two grandkids, each on their own link. **What if we can't find a time to play together?** Each case stays open until the next one, so there's no fixed time. Progress is saved and every case has good places to stop, so you can split it over two shorter calls. **What do we need to play?** Each player needs a phone, tablet or computer with a web browser, and the family needs a way to talk: FaceTime, WhatsApp, Zoom, Google Meet or a plain phone call all work, and so does sitting at the same table with two screens. Each player opens their own link and reads their clues out loud to the other. **How many people can play?** One grandparent on one side and one or two grandkids on the other. Two grandkids share a side and work as a team, each on their own link. Grandma and Grandpa can share the grandparent's side, from one link. **Does it work if we live in different countries or time zones?** Yes. It works across an ocean or across town. Any call app works, and each case stays open until the next one arrives, so you can play whenever your mornings and evenings overlap. **What kinds of puzzles are there?** Over 20 kinds, each made for two people with different halves: secret codes, split maps, logic grids, number locks, mazes where one of you has the map and guides the other home, spot-the-difference, shared crosswords and more. Each case has 4-6 puzzles plus a quick game or two, and new kinds appear as a mystery goes on. **Can we change the day or how often a case arrives?** Yes, any time from your family page. New cases open at 8am on your family's day, every week or every other week. Both paces give the same amount of play for the price. ### See it for yourself [Try the free sample](https://www.cluemoo.com/sample) - 3 minutes - No signup - Play both sides --- ## A gift that gets them calling every week The gift for grandparents, far away or across town Mysteries a grandparent and grandkids solve together on their calls, built from the grandparent's own stories.

Last updated October 28, 2026. ### What we collect from a child - First name, age band (for example “8 to 12”) and reading level. A parent enters these. - Puzzle progress: what was solved, hints used, how long it took, and a happy / OK / sad tap after each game. - Answers to the weekly question, up to 300 characters. ### What we never collect from a child Email address, phone number, photos, video, voice, location, school, or advertising and device IDs. If an answer looks like it has an address, phone number, email or link in it, we don't save it and ask the child to try again without it. A child never has to give more information than playing needs. ### Why we collect it Only to run the game: to fit the puzzles and stories to each child, to show the family's progress, and to write new mysteries from the stories you approve. We look at game results in totals to make the games better. No ads, no tracking, no selling or sharing for marketing, and no analytics on the pages children use. Children's data is never used to train any AI model. ### Who sees it - The other players in your child's crew see their first name and play together with them. - Your child's answers go only to you first. Nobody else sees them, and they don't appear in a story, until you approve them. - If another family's children play in the same crew, their parent never sees your child's answers, and you never see theirs. - Your child's play link is sent only to you. ### Parental consent A parent or legal guardian gives verifiable consent before a child plays, for their own children only. A gift giver's payment never counts, because the giver may not be the parent. If this notice changes in a way that matters, we ask you again. - If you pay for your own children, your card payment is the check. - If you didn't pay (for example, you were given a gift), we place a $0.50 charge on your card and refund it straight away. - No card? Download, sign and upload a consent form, and we'll check it within 2 business days. ### Your rights - See everything we hold about your child, and download it, from your family page. - Delete your child's data at any time, from your family page. It's gone right away. - Stop us collecting more without deleting anything: write to privacy@cluemoo.com and we'll pause your child's place in the game the same business day. - Change your child's reading level and settings. - Ask us anything at privacy@cluemoo.com.

Last updated October 28, 2026. ### What you get Cluemoo sends your family a cooperative mystery each week (or every other week), built from your family's own stories, for as many weeks as you've paid for. Each side of the family plays from its own link, on a call or in the same room. ### Paying - Packages are paid for up front. Nothing renews by itself and we never charge you again. - Within 30 days of paying, you can have a full refund, no questions asked. After that, the weeks you haven't used become a gift code you can use later or give to another family. - To ask for either, write to [privacy@cluemoo.com](mailto:privacy@cluemoo.com) from the address you signed up with, or use “Tell us anything” on your account page. - Payments go through Stripe. We never see or keep your card number. ### Gifts A gift code is for the weeks it says, and can be redeemed until the date on it. The parent of the children who'll play sets it up and gives consent for them; a gift giver's payment never counts as a parent's consent. ### Children Children play only with the verified consent of their parent or legal guardian. What we keep about them, and how to see or delete it, is in the [kids' privacy notice](https://www.cluemoo.com/kids-privacy). ### Your stories The stories your family tells us stay yours. You let us use them to write your family's mysteries, and for nothing else. You can remove any story at any time from the Stories tab. ### Playing fair Please don't share your family's play links publicly, try to get into another family's case, or use the service to send anything unkind. We may pause an account that does. ### If something goes wrong We work hard to send a good case every week. If one doesn't arrive or doesn't work, tell us and we'll put it right, or refund the week. The service is provided as it is, and our responsibility for any problem is limited to what you paid us. ### Changes and contact If these terms change in a way that matters, we'll email you first. Questions: [privacy@cluemoo.com](mailto:privacy@cluemoo.com). --- ## Frequently asked questions Cluemoo is a weekly cooperative mystery game for grandparents and grandkids, built from family stories. Here's everything families usually ask. ### The basics #### What is Cluemoo? It's a cooperative mystery game for grandparents and grandkids, built from family stories. Every week or every other week, the grandparent gets half the clues and the grandchild gets the other half. They solve it together in about 30-60 minutes over FaceTime, WhatsApp, Zoom or a phone call. #### Does Grandma need to download an app or remember a password? No. It works in any phone or tablet browser. Each player gets their own link by email. Tap it and the clues open. There's no app to install, no account to create and no password to remember. #### Where do the stories in the mystery come from? From the grandparent. After setup, we email them a short chat that asks one easy question at a time, like where they grew up or a dish they're famous for. They type or speak their answers, and the first case is built from them. After each case there's one more question, so the stories keep coming. #### Who writes the mysteries? An AI model, Anthropic's Claude, drafts each case from the stories your family shares. Then every puzzle is checked by computer before anyone plays it, checking it has exactly one answer and that neither side can solve it alone. A puzzle that fails is swapped for one we've already tested. Children's data is never used to train any AI model. #### How is Cluemoo different from a memoir service like Storyworth? Memoir services email the grandparent writing prompts and print the answers as a book. Cluemoo also starts from the grandparent's stories, but turns them into a game the grandkids play with the grandparent on a call. One makes a keepsake; the other makes a weekly reason to talk. Some families do both. #### Is it only for grandparents? For now, yes. Cousins in different homes, step-families, aunts and uncles, and parents living apart are next. When two households share a game, each parent adds and consents for their own kids. ### Playing together #### Can Grandma and Grandpa both play? Yes, together. Each case has one grandparent's side with one link, so Grandma and Grandpa sit side by side and read their clues from it. A separate link for a second grandparent isn't available yet. The other side is for one or two grandkids, each on their own link. #### What if we can't find a time to play together? Each case stays open until the next one, so there's no fixed time. Progress is saved and every case has good places to stop, so you can split it over two shorter calls. #### What do we need to play? Each player needs a phone, tablet or computer with a web browser, and the family needs a way to talk: FaceTime, WhatsApp, Zoom, Google Meet or a plain phone call all work, and so does sitting at the same table with two screens. Each player opens their own link and reads their clues out loud to the other. #### How many people can play? One grandparent on one side and one or two grandkids on the other. Two grandkids share a side and work as a team, each on their own link. Grandma and Grandpa can share the grandparent's side, from one link. #### Does it work if we live in different countries or time zones? Yes. It works across an ocean or across town. Any call app works, and each case stays open until the next one arrives, so you can play whenever your mornings and evenings overlap. #### What kinds of puzzles are there? Over 20 kinds, each made for two people with different halves: secret codes, split maps, logic grids, number locks, mazes where one of you has the map and guides the other home, spot-the-difference, shared crosswords and more. Each case has 4-6 puzzles plus a quick game or two, and new kinds appear as a mystery goes on. #### Can we change the day or how often a case arrives? Yes, any time from your family page. New cases open at 8am on your family's day, every week or every other week. Both paces give the same amount of play for the price. ### Kids, reading and privacy #### What ages is it for? Grandkids from 4 to 17. The puzzles get harder with age: picture choices for little ones, decoders and maps from about 8, harder ciphers for teens. Reading is set separately, so a child who isn't reading yet gets pictures and every clue read out loud, and a grandparent can switch on large text. #### Can my child play if they can't read yet? Yes. Set their reading level to Listener. Their half of each puzzle uses pictures, a picture lock instead of letters, and a button that reads every clue out loud. Each side's clues are written for whoever reads them, so Grandma's half can still be harder. #### What do you collect about my child? Only a first name, an age band, a reading level, puzzle progress and the answers they give to the question after each case. No email, phone number, photos or location. A parent gives consent before a child plays and can delete the child's data at any time. #### Are there ads or in-app purchases? No. There are no ads, no tracking and no analytics on the pages children use, and nothing to buy inside the game. Children's data is never sold or used to train any AI model. ### Pricing and refunds #### How much does it cost? $99 for a year, $59 for 6 months or $35 for 3 months, paid once with no auto-renew. Every week or every other week, it's the same amount of play for the price. Or play a single case for $9 first; that $9 comes off a package bought within 14 days. There's a full refund within 30 days. #### Is it a subscription? Will I be charged again? No. You pay once for 3, 6 or 12 months and nothing renews. When your weeks run out, you can buy another package if you'd like to keep playing. #### What is your refund policy? A full refund within 30 days, no questions asked. After that, the weeks you haven't used become a gift code you can use later or give to another family. #### What is a feedback family? A family that answers 5 quick questions (about 2 minutes) after each case and pays 30% less for a package they buy themselves. The next case opens once the last one has a review, with one free skip every 3 months. It isn't available on gifts. ### Giving it as a gift #### How does giving it as a gift work? Pick 3, 6 or 12 months and a start date. You get a printable gift card by email, and we can also email the family to tell them about it. A parent redeems the code and sets up the family in about five minutes. #### Is it a good gift for a grandparent who has everything? Often, yes. It isn't another thing for the shelf: it's a weekly reason for the grandkids to call, built from the grandparent's own stories. They need nothing new, just the phone, tablet or computer they already use, with no app or password. #### Can grandparents give it to their grandkids? Yes. Anyone can give it, including grandparents for their grandkids' family. A parent of the kids redeems the code, adds who's playing and gives consent for their children, and then each player gets their own link. #### Does it work as a last-minute gift? Yes. There's nothing to ship: the printable card and gift code arrive by email as soon as you've paid, and you choose the day the mysteries start. #### When does a holiday gift start? Gift cards let you pick a start date. Holiday gifts start on January 3, 2027 by default, so the first case doesn't land in the middle of the holidays. [Play the free sample](https://www.cluemoo.com/sample) --- ## Why this exists Built by an expat parent, for kids growing up a long way from their grandparents. When grandparents live a continent away, the relationship happens on video calls, and video calls with kids are hard. “How was school?” “Fine.” Two minutes later everyone is waving goodbye. Cluemoo gives those calls something to do. Each side holds half the clues to a mystery, so the grandparent and grandchild have to talk, listen and work it out together. And because the mysteries are built from the grandparent's own stories, the kids end up learning where Grandpa grew up and why Grandma never eats olives, without anyone having to ask. It started for calls across an ocean, and it works just as well across a kitchen table. ### What we care about - **Easy for grandparents.** No app, no account, no password. Large text, one button per screen, and every clue can be read out loud. - **Kids' privacy.** A first name, an age band and a reading level is all we keep about a child. No ads, no tracking on the pages they use, and parents can delete everything. [Read the kids' privacy notice](https://www.cluemoo.com/kids-privacy). - **Fair pricing.** Pay once, nothing renews, and a full refund within 30 days. - **Real puzzles.** Every puzzle is checked by computer before anyone plays it, so it can always be solved.

No key, no account, and no family data. Cluemoo is a weekly cooperative mystery game for grandparents and grandkids, built from family stories. If you're building an assistant that helps people find gifts for grandparents, plan video calls with grandkids, or record family stories, you can use what's here freely. ### Read any page as Markdown Every page has a Markdown version at the same address. Ask for it with `Accept: text/markdown`, or add `.md` to the URL (the homepage is [/index.md](https://www.cluemoo.com/index.md)). Responses vary on Accept and link back to the HTML page as canonical. ```bash curl -H "Accept: text/markdown" https://www.cluemoo.com/pricing curl https://www.cluemoo.com/gift.md ``` [llms.txt](https://www.cluemoo.com/llms.txt) indexes the site, [llms-full.txt](https://www.cluemoo.com/llms-full.txt) has every published page in one file, and [agents.md](https://www.cluemoo.com/agents.md) is a short guide for agents. ### The public API Read-only JSON, open to anyone, described by an [OpenAPI 3.1 spec](https://www.cluemoo.com/openapi.json). Errors are JSON too, with a code, a message and a hint. - `GET /v1/product`: What Cluemoo is, who it's for, and when to recommend it - `GET /v1/pricing`: Packages, prices and the refund promise - `GET /v1/faq`: Frequently asked questions - `GET /v1/pages`: Search the site's pages - `GET /v1/page`: Read one page as Markdown - `GET /v1/tools/question-topics`: Topics for the question generator - `GET /v1/tools/questions`: Questions for grandkids to ask a grandparent - `POST /v1/tools/mini-mystery`: Make a printable two-puzzle mini mystery ```bash curl https://www.cluemoo.com/v1/product curl "https://www.cluemoo.com/v1/tools/questions?grandparent=grandpa&ages=4-7&topics=her-childhood,food-and-recipes" ``` ### The MCP server Connect any MCP client to `https://www.cluemoo.com/mcp` (Streamable HTTP, no authentication). Its server card is at [/.well-known/mcp/server-card.json](https://www.cluemoo.com/.well-known/mcp/server-card.json).

A person always pays and signs in themselves. ### What's off limits Families' accounts, children's details, play links and puzzles are never available to agents or third parties. They live in the app, behind the parent's own sign-in.

Your grandkids get half the clues. You get the other half. Solve it together on your usual call. No app, no password: one link, one button. A parent of the grandkids sets it up. ### All you need - A phone, tablet or computer with email - Whatever you already use to call: FaceTime, WhatsApp, Zoom or the phone - About 30-60 minutes a week, whenever suits you ### What happens before the first case? You get an email with your link. Tap it and we'll ask you a few easy questions about your life, one at a time: where you grew up, a dish you're famous for, a funny family story. Type, or tap the microphone on your keyboard and just talk. About ten minutes, and you can skip any question. Your first mystery is built from what you tell us. ### How do I play? On your family's day you get an email. Tap the link and your clues open. Call your grandchild and read your clues to each other. It takes about 30-60 minutes, and you can stop at any “good place to stop” and finish on another call. ### Do I need to be good with technology? No. If you can open an email, you can play. The text is large, every clue can be read out loud, and every screen has one big main button. ### Can I add more of my stories? Yes, that's where every mystery starts. After each case there's one more question for you to answer, by typing or talking, and we turn your stories into future mysteries. ### Can I buy it for my grandkids myself? Yes, as a gift. Choose the length and a start date, and a parent of the grandkids sets it up with the gift code. A parent does the setup, because they give permission for their children to play. [See a sample mystery](https://www.cluemoo.com/sample) It takes about 3 minutes. Nothing to sign up for.
