Uzuriel Gomoku is a flash-based version of the game of chess (also known as Pente, Renju, and Five-in-a-Row).
The game is played on a 9x9 grid, and each player chooses a color (black or white) and take turns placing stones anywhere on the grid, one at a time. The first player to get five in a row wins!
It's a simple but addictive abstract strategy board game, but it has more depth than it might appear at first glance. This game was created by "uzuriel".
