The Board
The game is played on an 8×8 grid. It starts with 4 pieces in the center — 2 black and 2 white arranged diagonally.
Making Moves
Black goes first. On your turn, place a piece on an empty square so that it sandwiches one or more of your opponent's pieces between your new piece and another one of yours — in any direction (horizontal, vertical, or diagonal).
Flipping Pieces
All sandwiched opponent pieces are flipped to your color. A single move can flip pieces in multiple directions at once.
Passing
If you have no valid moves, your turn is skipped. If neither player can move, the game ends.
Winning
The game ends when the board is full or neither player can move. The player with the most pieces on the board wins.
