Play the ancient game of Go against your iPhone or iPod touch. Starting with the empty board, your goal is to surround territory — the simple rules of Go lead to a complex and beautiful game. This 4000-year-old board game originating in China is also known as igo (囲碁), wéiqí (围棋), or baduk (바둑).

SmartGo automatically adjusts the handicap to keep the game challenging, for beginners as well as seasoned players. Start with 9x9, and unlock 11x11 and 13x13 as your play improves. With a strong engine based on the latest research into Monte Carlo techniques, this is the game to beat.

SmartGo now comes in two variants: SmartGo 9x9 is limited to a 9x9 board; SmartGo supports boards up to 19x19.
