Coliseum

A new organic board shape every game. No two matches alike.

Coliseum generates a brand-new, irregularly-shaped arena for every game instead of the usual 8x8 grid, so no two matches look alike. Piece movement and check/checkmate rules still apply, adapted to the arena's shape. Because Stockfish only understands standard 8x8 boards, Coliseum uses its own dedicated local chess engine to play against you, or you can pass-and-play with a friend on the same screen.
