AI Merge Games

AI Merge Games has a free browser puzzle where you combine elements, such as Water plus Fire makes Steam, using 44 fixed recipes with hints, search and a recipe journal. There is no sign-up, and progress is saved on your device. A directory covers 12 mashup projects, including Isaac Survivors, Mari0 and NucleDoom.

Each project has a detail page listing its requirements and labels for AI involvement and playability. Downloads come from the creators' own sites, and some projects need a paid base game. The site also offers guides. It is independent and not affiliated with the games it covers.
