SmartGo One vs Expanding Tic Tac Toe

SmartGo One is the only Go app you’ll need, whether you’re just getting started or already a seasoned player. Learn, play, study, and improve with SmartGo One. Experience the ancient game of Go on your iPhone, iPad, or Mac in a whole new way. Also known as igo (囲碁), wéiqí (围棋), or baduk (바둑), Go begins with an empty board that gradually fills as players surround territory and capture stones. Start with a 9x9 board and move up to 13x13 and 19x19 as your skills grow. SmartGo One adapts to your strength, automatically adjusting handicaps so games remain competitive and enjoyable. And when you’re ready for a serious challenge, the powerful KataGo-based engine delivers strong, rewarding play. But SmartGo One is far more than a way to play Go. Read interactive Go books while replaying the moves they describe to deepen your understanding. Explore a collection of more than 138,000 professional game records spanning both modern and historical masters. Improve your reading and decision-making skills with a growing library of Go problems and tutorials. Want to know how a master would handle a position on your board?
