Q: Why did the system take points from me?
A: The system can penalize you during a game in four basic cases:
- If a player claims your discarded tile for mahjong.
- If a player declared Mahjong Self.
When a player declares a Mahjong Self – there are different variations in payment counting for European Classic, Mahjong Competition Rules, Hong Kong and other styles – but what they all have in common is that all the three remaining players pay the same number of points (except European or in Riichi).
- Wrong mahjong.
- The Uma penalty.
Point “3.6.1 Winner bonus” in the Riichi Competitions Rules.
Other insubstantial penalties are: The counter penalty, Dealer penalty, Riichi Bonus penalty and other penalties which do not take any significant amount of points.
