Get this, but don't buy the easy and hard modes! – Quadraticus HD Review

Until this application gets a major update do not buy, it freezes and has major glitches, the free version that u download now is good, but u have to purchase the easy and hard versions, and those have major glitches. Puzzle pieces get stuck and the touch is no good.... Update this app! Until then I'll continue to be mad I purchased the easy mode....
