I don't know if you can call this mahjong but it makes the game more challenging. And the music is more interesting than the usual oriental stuff. The squares are easier to read.

Like 3-D chess, but cooler

When I first looked at the title i truly thought of 3-D chess, but this is fun and addictive. Really great game, smooth phisics and graphics.

Great work

Wow

Ok, I just spent like... 3-4 hours playing.
Without stopping.

Lol, I think that tells you the game is pretty good :P
Although, I think that maybe making different difficulty levels or something would make it more interesting. Because both me and my friend came to the conclusion that the reason neither of us could really stop playing was because it was so boring it became fun, lol.
And I mean that in a good way. Had it been a bad way, I wouldn't have played this long. :P

Great

Simple and fun. Good combination of match game and physics game.

It's okay

Nice little game, although apart from the tile designs I don't see how this can be called mahjong
