Eleven pieces. Infinite strategy. Keep one in reserve to claim victory.
Each player starts with 11 pieces in reserve. On your turn, either place one piece on an empty point or move one of your pieces to a connected empty neighboring point. Moving is allowed immediately after your first placement.
Form three in a valid straight line (a mill) to remove an opponent's piece. Pieces already in mills are protected unless every opponent piece is in a mill.
No flying, ever. You win by blocking or completely eliminating your opponent, only if you still have at least one unplaced piece. If neither player has reserve when one is defeated, it's a draw. Three repetitions of the same full position also cause a draw.
Tip: Select one of your pieces to see legal neighboring moves. Tap it again to cancel selection.
