This game is very slow, instructions remain on the screen an inordinately long time, and it's simply clicking on groups of three or more to clear all blocks. When you have to use the scramble button before making the first move because the opening board doesn't have any matches on it, it makes you wonder if the game is designed correctly. The graphics leave a lot to be desired. If you can get more than 15 minutes into the trial, it may get better.
