good time learning to play


i'm really slow to pick up on Go but i love the game and SmartGo has been of more help than any tutorial. i simply keep playing, making moves not necessarily to win but to see the results, sometimes self-explanatory e.g. i didn't see a capture coming, or other times i need to back up a move and turn on the graph territory overlay before and after i drop a piece & SmartGo responds. i sometimes wish there were "opponent difficulty" settings for the "AI" but that's probably silly since you can (auto or manual) handicap. i learn a lot playing with a 5 stone handicap (i need 6 to compete hehe) then using hints for a follow-along example of how to win with a handicap i can't sustain yet. i play every day and learn and lose and win and laugh and punch my mobile in the face etc.. wonderful app.

Uses only optimal moves every time.


The app description led me to believe it taught the game. It doesn't. It simply corners you with the optimal move and often can't even beat itself if the hint system is used every move. The handicap system allows it to go first every time and since it knows the optimal move for every situation, you are not going to win any game that doesn't stump it within a few moves. If the board is full, it's going to beat you. The tutorials show and don't tell. There is no follow up to correct answers explaining why it's the best move. I would really like a refund as this isn't fun and is no substitute to playing a human. I came to learn how to fine tune my strategy, not watch a algorithm play out.

Developer Response

I’m sorry this app isn’t working for you; please contact for refund options. For much more extensive tutorials on the game of Go, please see the Go Books app. One clue: keep your stones connected, but make sure that you leave at least two empty surrounded spaces (“eyes”) so that your stones are safe from capture.

Great for learning


This is a great app for learning and improving your game. I also recommend "Tsumego pro" (a tactics app) and "Pandanet go" (a great way to play against humans) once you understand the basics. This app will teach you the rules (the app follows all the rules... It doesn't cheat as stated by some reviewers) and it will teach you some basic tactics and strategy. Then you can practice and see how good you get at one of the most complex games ever.
