Pentago is played on a 6x6 board divided into four 3x3 quadrants. A player wins by creating a line of 5 of pieces in a row. Each player's turn consists of dropping a piece on an empty cell and then rotating one of the four quadrants 90 degrees clockwise or counterclockwise. To move, first click on the empty cell where you want to drop a piece, and then click on the upper left or upper right cell in one of the four quadrants. The upper left cell will rotate the quadrant counterclockwise; the upper right cell will rotate clockwise.


Player 1 wins by dropping a red piece on the highlighted bottom cell, and then rotating the upper right quadrant counterclockwise to form a vertical line of 5 pieces.
