Less ad and easier puzzle piece handling.
It was ok except i dislike how the pieces returned to their spots if you didnt get it right, and sometimes it would grab a piece from under the one i am hovering the cursor over. and the ad took too long to go away.
Picky and sensitive.
It was okay, but I really hated that the game would remove my piece from the board if I chose the wrong spot or even barely missed. I would rather the pieces just lay where I put them; it's much less distracting.
