I can't get enough of this game. I love the graphics, but I have trouble with like colored stones. Some are so similar it's hard to tell them apart. I guess that is part of the challenge and observation is the key. I have a bunch of medals, but, I don't know how to save where I left off. Is there a way to do that? I have completed the game and still find it fun to return and try to do better with each level. Really fun time waster and it relaxes my anxiety. Love the ability to shut down the lights on this game. If you like match 3 games, this is one with a wonderful twist to it. You can challenge yourself and keep coming back to try and beat your own score. Fun, Fun, FUN!
