ChessCraft is a free chess sandbox game developed by Frame of Mind for Android devices. The game offers a unique experience for chess lovers by allowing them to create their own chess boards, rules, and pieces. With an AI computer opponent, players can test their creations and play against the computer or their friends online.

One of the most interesting features of ChessCraft is the ability to create new pieces with any combination of the 8 bishop or rook slides, plus a 7x7 grid of knight-like hops. These pieces can also enhance or restrict nearby pieces, adding a new level of strategy to the game. Additionally, players can create new boards with any enabled or disabled tile up to 16x16, and place promotion rules for any piece, anywhere. Tile rules like witch windows (teleporters), sanctuaries, and more make the experience even more exciting.

ChessCraft is a full and free game with no ads, except for occasional popups that ask players to buy ChessCraft Patron. Becoming a patron removes these interruptions. If you're a teacher, student, or cannot afford ChessCraft Patron, you can email the developer for a special code. Overall, ChessCraft offers a unique and exciting chess experience that is worth checking out.
