i enjoy the puzzles a lot; especially with the variety and different levels of difficulty. i would make a minor complaint about the ads, but it’s a free game, so it is what it is. one problem is the bug with the perfect fit game that does not allow me to place the final piece. when i put it onto the board, the position of the piece is slightly offset and does not allow me to complete the puzzle. by using up the hints i’ve confirmed that i have indeed solved it and decided to put the right puzzle piece in the right place, but i still cannot place the puzzle piece onto the board. i hope this issue gets resolved soon, and hopefully i get my coins back too. otherwise this game is great and i’ve recommended it to my friends as well :)
