Potentially great – Jewel Quest: Best Match 3 Games Review
Addictive and challenging without being impossible, but not nearly as good as the versions available for play on a PC. The main problem, as others have said, is the need to keep paying for more levels. I would prefer an in app purchase that buys the whole game early on; will most likely delete the next time I'm asked for $1.99 in order to play further.
