Flip A Smiley (air.com.bitlaslt.FlipASmiley) on Google Play
To complete a level you must make all the tiles in the play area turn smiley. You can change the face of a tile by clicking it,but that will flip the 4 adjacent tiles too.The fewer flips you make, the higher your score will be (score is tallied when you complete a level). Completing a level unlocks it so you can play it again later. Complete 20 levels to win the game. Good Luck!
