Crazy Gomoku 2.3
This strategy game, which is based on the Japanese GO, will challenge your brain at the most. In a 19x19 board you place alternating with your opponent one of your symbols. The point of the game is, to bring 5 of your symbols in a row (diagonally or straightly), before your opponent does it. If you don't know how to move, the computer will help you with a suggestion. If you don't see a chance to win, you can give up. The size of the board and the color and shape of the symbols are selectible.
