Incident Mahjong

Incident Mahjong is a Japanese Mahjong game set across a seemingly endless series of rounds. You must spot strange events during matches and solve Mahjong puzzles under special conditions to advance. Knowledge of Japanese Mahjong is required.

Spot strange events

In some rounds, you must click on problematic revealed or discarded tiles when you notice something unusual. Examples include declaring Reach (Riichi) while calling tiles, or calling tiles from the player directly across from you. If you finish a round without identifying its strange event, play returns to East 1.

Solve Mahjong puzzles

Other rounds set conditions you must meet to proceed, such as winning or drawing. You need to make the appropriate calls and discards to satisfy each condition; failing sends you back to East 1. A Strange Event Assist function is available, but understanding the basic rules of Mahjong is still needed for smooth play. Your goal is to reach victory beyond the final round.
