This is a really fun game. I like how challenging it is. I have one small problem with it. Once you get into the medium, hard, & expert levels some of the pieces get thrown behind the "i" in the upper left hand corner. The only way to get them out is to complete the puzzle except for the one lodged behind the "i" and then turn the puzzle until the piece fits. This is not always easy. If possible, could the creators of this game fix that little problem? Other than that, its a great game. Thanks.
