Many chess AI mobile games already exist, but only ChessCraft allows the player to create such wacky boards and pieces and immediately play a decent computer opponent.
Create new pieces with any combination of the 8 bishop or rook slides, plus a 7x7 grid of knight-like hops. Pieces can also enhance or restrict nearby pieces. Create new boards with any enabled or disabled tile up to 16x16. Place promotion rules for any piece, anywhere. Place tile rules like witch windows (teleporters), sanctuaries, and more. The computer AI opponent then uses concepts from computer science and graph theory to understand your creations and play against you.
When you share a board, your friends can play the AI too. Sharing creates a new web page just for you, like this:
ChessCraft is full and free with no ads, except for the occasional popup which asks you to buy ChessCraft Patron. If you become a patron, you won't see those interruptions anymore. If you're a teacher, student, or you cannot afford ChessCraft Patron, send me an email and I'll send you a special code.
Visit the website and send me an email if you have any feedback or questions. If you like the game, please rate it!
