It's fun until Level 7, which is entirely luck-based but otherwise unplayable. Knowing that you have to get matches of THREE at least to advance the game, you have very little room and you often have combinations of gems that are less than three. To make matters worse, the timer is running and you have very slow gem loading/dropping sequences in this game, which chops away precious time which could be used to finish the level!
2.5/5. I gash away half the score for playability.
