middle of the board. The tiles have the same color at each

Black goes first and places a tile on the board such that it
traps white's tiles between two of black's tiles. When black places
a tile on the board all of white's tiles between black's newly placed
tile and another black tile, in a horizontal, vertical, or diagonal row, are flipped over
and become black, as shown in .

When there is tile trapped between two tiles, of an identical color
in the same row, the player captures tiles until another tile of the
player's color is encountered, as shown in .
The player can only take tiles that are
a direct result of the placing a tile on the board. Once a tile is
placed on the board the player cannot remove it and place the tile
somewhere else. If a player cannot move they forfeit their turn.
The game ends when it is no longer possible for either player to move.
