Three types of AI games

• Make games with AI: services where you give instructions in writing and AI makes the game for you. Some let you publish your game for others to play.
• Advance a story with AI: mostly text-based games where AI writes the story and the player types actions to move it forward.
• Smartphone games that use AI: app-style games where AI handles judging and conversation.

Make and publish games with AI

AI Game Builder (WillBooster)

A service where you write instructions in Japanese and generative AI makes the game automatically. It states that no programming knowledge or software is needed. You can give your game a title and publish it, play other people's games and press "like". The official page has a "make a game for free" button (check the official site for pricing details).

DreamCore

Cautions when using AI games

1. Check the terms of use: the rights to games you make and the conditions for commercial use and sale differ by service.
2. Check pricing and credits: even if you can start free, there may be limits on the number of generations, or some features may be paid.
3. Don't enter personal information: what you enter into an AI may be stored or used by the service.
4. Watch age and content: you may not be able to check user-made works in advance. If children are playing, have a parent check.
5. Treat generated output as a starting point: the first result often needs touching up.

Free browser games without AI are great too
