Today's Free App of the Day is Montezuma Puzzle 3 Premium
This is a fun puzzle game; you get a set of irregularly shaped pieces and have to fit them into a hexagon grid. You can earn up to three starry things on each level based on speed and whether you use hints or not. (The question mark in the upper left hand corner.) You can start over and the stars reset.
I'd say this is a solid four star game--it's lower than that because people are really angry about the review nagging.
There's a major blowback against the game's nagging to review it, which I agree is annoying. However, as several reviewers say, you can stop the nagging by either reviewing it, or, if you're not ready, tapping on OK and then using the back key in the side/bottom menu to go back to the game. Once you do that, no more nagging whether you reviewed or not (at least so far).
