Standard chess against the AI. Pick white or black — white always moves first.
Multiplayer — host plays white (first).
Pick your side.
Click a piece to see its legal moves, then click a destination. N for a new game.
Difficulty is locked while a game is in progress (including pawn promotion). Finish the game or start a new one, then open settings before you play.
Low settings play mostly random moves. Above ~85% the randomness is gone and the slider buys search depth and thinking time instead — 100% is the engine at full strength.
Only changes how the pieces look. You can switch any time, even mid-way through.
