The game that uses mahjong tiles isn’t mahjong at all, but bingo. After you pay you can choose a certain number of tiles, usually around 13, then you just turn them over and match them to the board. A bingo gets a prize. You usually pay 100nt for maybe 5 tries.
I slowly turn over each tile, cheering myself on when I get a good draw, and acting sad when I don’t. Purely for dramatic fun.
If you end up with 聽 (“ting” - need only 1 more tile for a bingo) the proprietor will often give you a couple more tiles to keep trying. However, if you bingo on the extra tiles you won’t get a big prize but maybe a free chance to play again or something.
The good proprietors will turn over the unused tiles at the end of the round to show you that the game is fair.
And now you can join in the fun! ️
