Usually, I play Mahjong in a company, but after playing the online version of Mahjong where you need to find pairs, I wanted to experiment and tried to build a castle without seeing what pieces I was choosing and placing on top of one another.. Welpppp, it worked just once, other times the castle was doomed to be never disassembled cuz there were no pairs EVEN in the first layer of the castle HAHAHAHHA lol didn’t work
