The board supports the full rules of chess, including castling, en passant, underpromotion, check, and the conditions that end a drawn game. Use the sample to name the audience, the main action, and the smallest useful first version. Cleo HQ then helps turn your own brief into a product plan and a working build.
The game handles castling, en passant, and underpromotion alongside check and checkmate. It also recognises stalemate, insufficient material, and the fifty-move rule. Those details matter because a chess game should end for the right reason, not simply when a king is trapped.
The opponent looks for pieces it can take without losing material and searches for ways to deliver mate. Legal-move highlighting shows the player what a selected piece can do, while the board can flip to either colour's perspective. A player can therefore study the board at their own pace instead of racing a clock.
Yes. The player can choose either colour, and the board flips so their pieces remain nearest to them. That small display choice makes a familiar board game easier to read for people who want to start from the opposite side.
