Then after watching the documentary AlphaGo, I went searching and found this great app. The lessons and puzzles were exactly what I was hoping to find.

High Quality

The production value on this app is really good. I love the gamification of the user ratings with specific goals to achieve to rank up. The graphics are fun and the interface is nice. I don’t know how many people are playing online (which can be a big factor in longevity) but I definitely think the style of this app helps making learn go more interactive and fun. Keep it up please don’t let the app stagnate and die off!

Good app, but confusing lessons/puzzles

I’ve learned go from absolute beginner using this app to some extent, but I’m continually frustrated by the lack of explanation or follow-through in the lessons and puzzles. The explanations given don’t really explain why “the group is saved!” or “Oops, the group is dead.” If they would only show what actually happens if the puzzle were played through to its conclusion (capturing stones, etc.) or what makes a group dead, then I think I would get a lot more out of the lessons and puzzles. I’ve honestly gotten more out of just playing 9x9 online using this app, and have been able to occasionally even win against much more highly rated players. I still often struggle to recognize when I should stop trying to capture a group or even resign and am sometimes surprised that I scored so low (or high, as the case may rarely be). I just feel a lot of the time like I’m missing something and have to look things up on websites like Sensei’s Library, where if the app could just explain puzzle reasoning better I may not have to.

I like it but it needs an update

I like watching Asian dramas and this game is a constant feature in both historical and present-day dramas. So I decided to research how it’s played. The tutorials are helpful, and I appreciate the ability to collect puzzles that I got wrong. I wish it would explain why a move is wrong because I don’t always understand the correct answer. But it is still very good considering it’s free. I’m only on level 1 and I lose 90% of the time. However, the last few times that I won against AI Bobby in points, the app said I lost to him on time. What’s up with that? Am I missing some timer rule or is AI Bobby a sore loser? I do like the app, but I hope the developers can fix this issue so I’m not losing my game play tickets unnecessarily.
