Many a schoolday was wasted with endless games of Go (or 'Squares' as we called it) while the teacher wasn't looking. Anyone who enjoyed missing out on all that knowledge in the pursuit of fun can now play the game without fear of being caught, on their mobile phone thanks to GnuGO.
As in its original format, your objective is to build the largest possible boxes in order to surround your opponent and 'capture' their squares. As always, you'll need sharp concentration skills and slight of hand in order to beat the highly adept computer opponent, which actually learns as the game goes on. In your favour though is an automatic helper that validates your moves. There's also a two player mode if you're fed up losing to the phone and want to inflict some of this misery onto a pal.
Although the graphics in GnuGO are pretty feable, the game is highly addictive and the challenge of defeating the skilled computer opponent will keep you coming back for more.
