The ultimate test of your Mahjong skills is what you will find when you select Mahjong Dark Dimensions: 210 seconds. With a time limit of only 210 seconds, you have to be a master of finding the matching tiles, and on top of that the game is played entirely in 3D! Mahjong Dark Dimensions: 210 seconds lets you extend the length of a round if you match the tiles with the time bonus on them, but the same rules apply to these as well: you can only match tiles that are on the edge of the stack, so you might have to clear your way to get to them. Play a fast round of Mahjong on Wordgames and see how quickly you can match the tiles.
