💡 Scoring Tips
📐 Fu Rounding Rule: Always round fu up to the nearest 10. For example, 23 fu becomes 30 fu. The final point total is also rounded up to the nearest 100 (for ron) or 100 per player (for tsumo).
🎯 Mangan Threshold: A hand reaches mangan (8,000 pts dealer / 8,000 pts non-dealer ron) at 5 han, or at 4 han with 30+ fu, or at 3 han with 70+ fu. This caps the score regardless of fu.
💸 Honba Sticks: Each honba stick on the table adds 100 points per player in a tsumo win (300 total) or 300 points in a ron win. These stack with riichi stick pickups.
🀄 Dealer Multiplier: The dealer always receives 1.5× the non-dealer ron amount. In tsumo, all three opponents pay the dealer equally, so the total is 3× the per-player amount.
Riichi Mahjong is simply the Japanese version of the old Chinese game. Because four players seat around the table with tiles in the hand, the main goal is to complete his hand more quickly than the opponents for more points. It obeys the basic rules of other mahjong styles, even so it has its own character (special elements), that really strengthen the fun.
Statement of riichi is what separates this game. If your hand stays closed (that means, that you did not take any tiles from the other players) and you require only one piece to win, then you deserve to declare riichi. One calls that situation tenpai.
Basics of Riichi Mahjong
Declaring it is like all-in in poker; you take a brave step, that promises big prize, but face also real danger.
To declare riichi, you must do three things: one says it loudly, turn the last dumped tile face down on the table and lay 1000 points as stick beside the discard pile. Those 1000 go to the one that ultimately wins the hand. When the hand ends without a winner, the sticks simply stay there, waiting for the next success.
But here is the catch. If an opponent took your dumped tile for his victory, your riichi statement disappears, and you lose his 1000 points.
Riichi ranks among the most common yaku, that you will meet during the game. Yaku are base patterns for victory or special states, taht allow you to declare triumph. Not all yaku require unique tile combinations; some depend only on the circumstances, like riichi itself.
When you declare riichi, you already set one yaku, and if you successfully end the hand, you can gain even more points.
So, there is the rule of furiten, that commonly confuses newcomers. When you dump tiles, and one of them later becomes your winning tile, you can not use it. The only weigh to win by means of that tile is to draw it directly from the wall for the rest of the round.
The game adds also dora tiles into the mix, which simply shows that luck plays a bigger part. This surprise is almost what makes Riichi Mahjong so fun and stops matches from feeling boring. It became the most favourite version in Europe, and everything that the European Mahjong Association officially plays.
Newcomers commonly feel that the whole set of rules and tactics seems too heavy at first sight. It is smarter to learn the basics before going more deeply. Getting used to table wind, dora, han and simple yaku like tanyao, pinfu and toitoi can happen after which the main tile steps no longer feel strange.
The good thing about this game is how it sometimes rewards wild choices and rewards good habits in other moments. Even top level pros last bad periods, while total beginners sometimes getlucky.
