5 stars: I find that though I sometimes exit out of this particular game that I keep coming back to it. its challenging and fun, not boring.. you CAN go back to where you left off, but its on the face if your phone where you clear all the apps you've been to and they contain the ones you've opened yoy can cluck back into where you left off. I like it very much. At my age it allows me to keep my mind active and alert, I give it a 10 star.
4 stars: Lacks one really important feature: there is no way to save a game. If you need to stop, when you come back you have have either to start that level over or jump to the next level. I personally would like to be able to return and finish a level without starting over. Apart from that I LOVE the 3D aspect- so much more interesting than regular mahjong.
4 stars: You can save a game by clicking the home icon, and when you next launch the game it comes up with a continue, so I am not sure why people are saying you can't save games. The only thing that is incredibly annoying is the trees! I am playing on android, and it is super annoying, other than that, a good game. I like that there is no undo button, to me that is cheat mode haha..
3 stars: i like it but manuvering within the game can be frustrating. One minute you're working on one puzzle and you move slightly to find yourself working on a totally different puzzle. The zooming in and out to try and figure out where you are is a bit annoying too.
2 stars: Good game, but...
