Absolutely wonderful. Large skill range, and options to ease stone placement on mobile devices. Only thing i would like to know is the estimated skill (in kyu or dan) of each of the "levels" as they are only listed as "level 1 - level 9"

Nicely presented but very predictable in move selection. Feels to me, a humble 1kyu, more like an old-style engine than a state-of-the-art Monte Carlo engine, but I'm probably wrong about this. Someone should lend it a copy of '38 Basic Joseki' for a start! It also has a rather aggressive playing style and it would be great if it could offer a range of styles. It also needs to stop trying to cut bamboo joints and to learn the difference between sente and kikashi.

Strong engine but makes strange plays in the opening sometimes. Also, what was the latest update? No mention if it was bug fixes or the long awaited landscape mode which it was not....clue us in on what we are downloading ffs.

I pay for the sub and expect it to be at least at 5d level... why can I still be able to beat it in the even game when I was only kgs 1d :/,

The crazy stone engine is not bad, compared to GNU Go, but it's play style is still way too mechanic to be enjoyable. It always tries to win by smallest possible margin, resigning every time it starts to lose, doesn't punish obviously bad moves unless you choose the strongest level. On weak levels it mostly plays random moves and resigns at random, which is really boring. It always opens handicap games in exactly same way: If you play a 2 handicap game on 9x9 against it, it will always start by playing 4-4
