How to play

Tap one of your pieces, then a glowing square. Dots are free squares. Red rings are captures. A red king is in check.

Each side has an army bar. It drops when pieces are lost: pawn 1, knight 3, bishop 3, rook 5, queen 9. It is only a score. You win by checkmate.

The Menu button has undo, new match, worlds and settings. Two players share one screen: tap the turn button to spin the board.

Keyboard: arrow keys move, Enter chooses, Escape clears. Castling, en passant and draws follow the real rules.

Championships
