SmartGo One is the only Go app you’ll need whether you’re just getting started with Go or are a seasoned master. Learn, play, and win with SmartGo One!

The ancient game of Go can be enjoyed on your iPhone or iPad in a whole new way. Also known as igo (囲碁), wéiqí (围棋), or baduk (바둑), Go starts out with a blank game board that fills as you work to capture territory and stones from your opponent.

You can start with a board size of 9×9 and then move onto larger ones measuring 13×13 and 19×19 as your skills grow. SmartGo One increases its difficulty as players improve, with an automatically-adjusted handicap ensuring you’re never playing an opponent that’s beyond your capabilities. But don’t be fooled into thinking SmartGo will hold your hand — you’ll still be challenged! With a strong engine based on KataGo, expect a battle as your improving skills demand it.

SmartGo One gives Go fans a way to play, but it goes far beyond that. With SmartGo One you’ll also be able to read books about Go while replaying moves that those books describe to help you get a better understanding. A collection of more than 115,000 pro-level game records means you’ll never stop learning from masters both modern and much, much older. Players can also take advantage of a growing library of Go problems. Solving those problems is a great way to improve your in-game decision making.

Stuck or keen to learn how a master would play any position you find yourself in? SmartGo’s pattern matching technology will cross-reference your game board with those of historical games, showing you how other players dealt with the situation at hand. No matter your level of skill, SmartGo One will help you improve.
