If you've never heard of it, then Gomoku is a classic Japanese puzzle game also known as Five-Stones, Five-In-Row, Five-In-Line, Tic-Tac-Toe, Make-Five, Renju, Gobang and Piškvorky.
The rules are simple - to win you must have a continuous line of five stones of the same color. Like in Connect 4 - the The line can be either vertical, horizontal or diagonal except there's 5 instead of 4 of course! You can select between wither the devil or an angel as your player of choice and can choose one of three strategies and 5 possible levels.
mGomoku features some very colorful graphics, some natty visual effects plus the sound effects aren't bad either. You can choose your level of difficulty although the higher levels are virtually impossible to master. It would have been nice if you could have a two player mode too but as it is, you'll just have to settle for playing against your PC.
mGomoku isn't the most original puzzle out there but it delivers more than a fair few hours of entertainment.
