FreeSweetGames Crossnull

The Crossnull is a version of Renju. The game is played on a 15 x 15 board. The first player places a cross piece on an empty cell by turn, the second player places a null. The one who place five pieces in a row (vertically, horizontally or diagonally) first wins. In case all board is filled, and the row of five identical pieces is not made, the drawn game appears.
