Build a few tiny browser games around what your child loves. Each one reveals a piece of a code that leads to a present you hid.

You'll end withA browser quest, plus a present you hid yourself

The present is already yours to hide. The game only hands out pieces of a code. In the post, the themes were things that child loved: K-pop, cats, drawing, simple arcade games, and puzzles. You can use interests. You do not need a name.

Who does what

Kid does

  • On the day, plays the levels and writes down each code piece
  • May help pick themes beforehand, if the surprise can survive that

Parent does

  • Chooses themes that are not private facts
  • Builds the game on your Claude account
  • Sets the real code, hides the present, and plays it once yourself
  • Stays nearby while they play. 10–12 is still with a parent.

Materials

  • A present you have already chosen
  • Paper for the code you will hide with it
  • Your Claude account and a browser, including a tablet browser if that is how they will play
Leave out of the prompt: their name, the date of the birthday, the school, the town, and the actual gift.

Steps

  1. Parent List three interests as themes. “Cats” is enough. A specific classmate, school, or address is not.
  2. Parent Paste the quest prompt and read the level plan before you say go.
  3. Parent Play every level. The post says a few rounds of back-and-forth were enough, and that the game felt almost native on an iPad. Yours might not. Fix a confusing level before the party.
  4. Parent Replace the code with one you chose, if the game will let you. Write that code on paper and put it with the present.
  5. Parent Hide the present in the house. The game should not contain directions to a real place.
  6. Kid Play and collect the pieces. You stay in the room.
  7. Together Open the present when the code matches. The computer does not need to be there for that part.

Copy-paste prompts

Level 10 quest

The main prompt (parent pastes this)

I'm a parent building a single-player browser game as a birthday quest. The player is turning [AGE]. Please make a short game of [NUMBER] tiny levels. Each level is about one interest I'll list. At the end of each level, show one piece of a code. I'll hide the present in the house and write the matching code on paper. You do not need to know what the present is.

Interests (themes only, no real name, no school, no town, no birthday date):
[INTEREST 1]
[INTEREST 2]
[INTEREST 3]

Please:
1. Describe the levels in a few lines and wait for me to say go.
2. Build a browser game that works with a finger or a mouse, including on a tablet browser if you can.
3. Tell me the full code and which level reveals each piece, so I can set the real code myself.
4. Use made-up labels. Do not use a real child's name or a celebrity's exact name.

If you can't make a level about one interest without copying a real song, show, or person, swap that level for a simple puzzle and say so.

Fix one level

If a level is confusing

Level [NUMBER] is confusing when we play it. Here is what happened: [WHAT HAPPENED]. Please change that level only, keep the same code pieces, and tell me how to open the new version.

What you’ll end up with

A short browser game and a present you hid. The post includes a photo of a screen. We are not republishing it. There is no photo from our own run.

Safety box

  • Age guidance: 10–12 is limited use with a parent. You hold the Claude account. 13+ can draft with you nearby. Safety & Ages hub
  • No personal info. Interests are themes. A real idol’s songs and videos are not yours to paste in.
  • Not a friend. The game is a quest, not a character who misses them.
  • Play it yourself first. A broken level on the morning of a birthday is a bad surprise.
  • The present is ordinary party safety: small parts, allergies, and where you hide it are your job. The post does not discuss them.
  • Price: stop if Claude asks for a payment you were not expecting. The post is silent on cost.

Age adaptations

AgeHow it worksTips
10–12You build. They play. The post’s child had just turned 10.Three short levels beat a long one. Test on the same tablet they will use.
13+They can help write the brief, on your account, with you next to them.They still should not put a real name or a school into the chat.

Variations & next projects

  • No code at all: three paper puzzles can reveal the same digits. Use the treasure hunt if you would rather print clues.
  • A younger child gets the paper version. Do not hand them Claude.
  • Keep the screenshot private. A game over screen can still show a name if you typed one. Don’t.

Source & inspiration

A single-player “Level 10” browser game, themed around a 10-year-old's interests, with each mini-game revealing part of a code to a hidden present, comes from Alexander Gilmanov's public post. He names Claude, a few rounds of changes, and a game that felt almost native on an iPad. The steps and the prompt here are ours. We do not know the present, the exact code, or how long the build took.
