A Unique Card Game That Tests Your Concentration

zMahjong Concentration is a tile-based game that puts your concentration levels to the test. The game looks fairly easy and simple at first. However, truth reveals itself after you actually start playing the game. To get rolling, select a tile randomly as reference tile and try locating and removing all tiles that are the same as the reference tile. And you have to do this in the shortest possible time. After all the identical tiles have been removed, you may tap and eliminate the reference tile. All tiles must be removed to conclude the game.
