Let's play Black Friday Mahjong online!
Click on two tiles that are free, without anything blocking the path from one to the other, and if they are the same. When you do, these pairs are removed, and you win each level by removing all pairs of tiles by matching them in this way.The green timeline slowly decreases on the right side of the screen, so the more it is left out, the more extra points you get between levels. Each new one is more difficult than the previous one.
