Each player has nine pieces. First take turns placing them on empty points. Once all yours are down, move one piece per turn along a line to a neighbouring empty point.
Line up three along a line to form a mill, then remove one of your opponent’s pieces. Pieces in a mill are safe unless every one of theirs is in a mill.
With only three pieces left, a player may fly to any empty point. You lose when you are down to two pieces or cannot move. Fifty moves in a row without a mill make the round a draw.
Scores carry across rounds, and the starting player alternates each round.
Red pieces carry a cross and Blue pieces a ring. Tap a piece, then where it goes. Keyboard: arrow keys move between points, Enter or Space picks one, Escape lets go of a piece, Ctrl+Z (Cmd+Z on a Mac) undoes.
