Can you escape from the never-ending strange Mahjong game?
※Knowledge of Japanese Mahjong is required to play this game.
"Strange Mahjong" is a Mahjong game where you need to notice "strange events" happening during the match. It consists of rounds where you must point out these "strange events" and rounds where you solve "Mahjong puzzles" under special conditions.
In the rounds where you need to point out "strange events," you'll have to click on problematic revealed tiles or discarded tiles if you notice something strange, like declaring a Reach (Riichi) while calling tiles, or calling tiles from the player directly across from you. If you finish a round without pointing out the strange event, you'll be sent back to the first round of East 1.

In the "Mahjong puzzle" rounds, you’ll be given specific conditions like "win or draw to proceed." You'll need to make the appropriate calls and tile discards to meet the clear conditions and proceed. If you fail to meet the conditions, you'll also be sent back to East 1.

Show off your Mahjong skills and aim for victory beyond the final round!
Note: While there is a "Strange Event Assist" function, you will need to understand the basic rules of Mahjong for smooth gameplay.
