I could play this game for hours!!! Buuut the limited life feature only lets you play for about 15 minutes before you run out of lives and have to wait 30 minutes for ONE more life. After about 100 levels (which only takes a couple days to reach), it no longer becomes a game of logic and skill but instead is just random luck and guessing because you can't see what's under the top tiles. Entertaining for about a week and then it's time to delete
