Prompts for making games with AI

Requests you can paste straight into ChatGPT, Claude, Gemini and more. Publish the game you get on Asobiai as-is.

Prompts by genre

Examples written by the Asobiai team. “Copy” gives you the full request, including mobile support and leaderboard conditions. Rewrite the idea part however you like.

🔘One-button jump game

A penguin jumps when you tap (or press Space) and dodges ice pillars scrolling in from the right. The distance is the score, and it speeds up over time.

☄️Dodging game

Move a spaceship left and right to dodge meteors falling from above. Grabbing the occasional star gives a 5-second shield. More meteors appear over time.

🧱Breakout

Bounce the ball with a paddle to break blocks. Blocks marked with a star drop items (wider paddle, triple ball). Five stages.

🧩Falling-block puzzle

A falling-block puzzle where 3 or more blocks of the same color in a row vanish. Blocks above fall down, and chain reactions multiply the score. Show the next piece.

❓Multiple-choice quiz

A 4-choice trivia quiz. 10 questions per round; faster answers score more. Write 30+ questions and pick them at random each time. Add effects and sounds for right and wrong answers.

🧠Memory game

Panels in a 3×3 grid light up in order and you tap them in the same order. Each round adds one more. A mistake ends the game; the length you remembered is the score.

🎵Rhythm game

Notes fall down four lanes; tap them (or press D, F, J, K) as they cross the line. Make the music with the Web Audio API and judge timing as PERFECT / GOOD / MISS.

🤝Online two-player game

Online tic-tac-toe with a friend. Read the Asobiai SDK docs (https://asobiai.games/docs/sdk), join a room with window.AIGame.joinRoom and send moves with room.send. Show the room code so friends can join.

Prompts for fixing

Play the game, then follow up with requests like these.

  • Make it playable on phones with touch controls. Put big buttons at the bottom of the screen
  • Make it easy at first and a little harder every 30 seconds
  • Add sound effects and music with the Web Audio API, plus a mute button
  • Support the Asobiai leaderboard (call window.AIGame?.submitScore(score) on game over)
  • Read the bug reports on Asobiai, fix them and update the game
