5 stars: Good game, fun. It's like reverse Tetris. Definitely recommend for a time killer!
4 stars: Good game to spend your time.
3 stars: Fun concept but without progressively harder objectives or achievements to aim for, the game gets boring quickly. If you do want to submit your score this takes ages. Ads on the bottom of the page and between every new game.
3 stars: An interesting idea, but the inability to twist the pieces makes it too restrictive. You can see good moves but the game won't let you make them.
2 stars: Too many ads, app is glitchy.
2 stars: The game summary (with 'New Game' button and the final score) disables the mechanism of the back button. Developer fail! Edit: Generally when you press back, the expected function is for the app to exit with confirmation. This app doesn't do that and it's annoying
