Zamma

Alternate placing two tokens per turn on empty squares until the board is filled except for the center square.

Whoever placed the last token sits out a turn, letting the opponent slide first into the open center.

On each turn, move one token to an orthogonally adjacent empty square.

Capture an opposing token by flanking it on two opposite sides with your own tokens in a straight line.

Remove captured tokens from play immediately; they cannot return to the board.

Play ends when a player has no tokens or no legal moves, and the opponent wins the game.
