ShangHai Mahjong Ext 1.4.0

It is a game to erase stacked mah-jong tiles with pairs of the same tiles.
Tiles that can be deleted can be taken if either the left or the right is empty and there is no tile on top.
I compete for the time spent hiding all the tiles.
There is always an answer.
You can display remaining hands and display tiles that can be erased.
If the remaining number is 0, the game is over, so if you think it is dangerous, please return the state and try again.
You can inquire about the top 100 grades.
You can choose from twelve patterns for placement of tiles.
