This is a simple tile game. The main screen is divided into two identical tile areas. On the top area, the system will randomly flip a tile, and the player needs to tap a corresponding tile on the bottom area based on what the current game mode is. For example, if the game mode is up-down, then the player should tap the tile (on the bottom area) that is vertically opposite to the one flipped by the system (on the top area) in order to score. Other modes include left-right, copy/same, and diagonal (NE-SW or NW-SE).
Players can also change the play area size (2X2, 3X3, 4X4, 5X5, and 6X6) as well as the game ending rule (one life, 15 seconds, or 20 correct tiles). Available in-app purchases include custom tile pictures/shapes and ads removal.
This game can help the player exercise the brain and improve the reaction time under different conditions. Video: http://www.youtube.com/watch?v=l9RMk5zvpgQ
