Trirra for PC

The goal of Trirra is to capture as many cells on the playing board as possible with your chips. The game starts from the corner cells of the board. The right of the first move is chosen randomly. Opponents move in turn.
You can place a new chip only in cells that directly border your chips in all directions (up and down, sideways and diagonally).
If three cells occupied by your chips border on a cell occupied by an opponent's chip, the opponent's chip disappears and the cell is freed. If a row of chips of one player is broken, then the chips that are not in contact with the others also disappear. You cannot place a chip on an empty cell that borders on three opponent cells, as it implies that your chip should immediately disappear.
If a move to a certain cell is impossible for both opponents, this cell of the field is deactivated.
After the moves are exhausted (there are no moves that will lead to an increase in your territory), the game ends and the chips are counted. The one with the most chips on the board wins.
