The winner is the first player to get an unbroken row of five stones horizontally, vertically, diagonally. GomokuPro is a professional Gomoku game and features ban rules to offset the first move advantage of black player. By ban rules, black is prohibited from making a double three, a double four and an overline. If black makes one of these patterns either accidentally by being forced to, he/she loses the game. It is definitely more fun with ban rules. GomokuPro probably has the best AI on the Marketplace. Trust me! it is not easy to beat GomokuPro.
