Bonus tiles cannot be the only reason for winning.
✓ Requirement met
Yaku+Dora
At least one yaku
Check a valid yaku first, then count dora. Furiten can still prevent ron.
These diagrams explain one requirement at a time, not a complete winning-hand check.

Four sets and a pair, plus a yaku
Japanese Riichi usually uses four sets and a pair. Seven Pairs and Thirteen Orphans have special structures. A legal win needs a yaku; dora are bonus tiles and cannot supply the missing yaku by themselves.
Riichi, open hands and furiten
A closed hand in tenpai may be able to declare riichi. Calling tiles opens your hand and can remove some yaku. Furiten can prevent ron even when the tile completes your hand; check your own discards as well as your waits.
Han, fu and payments
Yaku and bonuses contribute han; hand details can contribute fu. Dealer status and ron versus tsumo also affect payment. For example, a non-dealer ron of 1 han and 30 fu is 1,000 points before honba and riichi sticks. Coin games display competitive points and rank changes.
Before you press Win
Identify a yaku first, then check the winning tile and any furiten restriction. A beautiful hand with several dora can still be unable to win without a yaku. East and South games can include repeat dealer hands, so their actual number of hands can vary.
No. Under mahjchina’s Riichi rules, a hand must qualify with at least one yaku before dora or ura-dora are added. A complete shape with dora but no yaku cannot win.
Winning conditions, calls, draws and settlement for this ruleset.
Basic rules
Uses WRC 2025 hand and scoring rules, without red fives. Each player starts with 30,000 points. Friend rooms offer East or South matches with dealer repeats and honba.
A yaku is required
A regular hand has four groups and a pair; seven pairs and thirteen orphans are also supported. At least one yaku is required. Dora and ura-dora alone never qualify a win. Results show yaku, fu, han, dora and payments.
Riichi and furiten
When eligible with a closed ready hand, choose a riichi action with its discard. An accepted declaration places 1,000 points in the deposit pool. Furiten blocks ron but permits tsumo.
Responding to a discard
Ron takes priority over pon and open kan, which take priority over chi. You can only chi the previous player’s discard. Passing on ron may cause furiten.
Kan and dora
The table shows dora indicators; the next tile in sequence is the dora. Winning on a kan replacement may count as rinshan kaihou. Added kan can be robbed, and kan after riichi has extra restrictions.
Draws and results
After a draw, results show each player’s tenpai status and point change. In friend rooms, honba and riichi deposits carry over according to the rules.
Value
mahjchina Riichi profile: double-wind pair 2 fu; renhou as a separate 5-han alternative; kiriage mangan enabled; no special-wait double yakuman. Tournament and other platform settings can differ. Rule choices & sources →
At least one yaku is required before dora or ura-dora count. Two values in the table mean closed/open. Riichi, ippatsu, pinfu, iipeikou, ryanpeikou, seven pairs and menzen tsumo require a closed hand. Renhou is a separate five-han alternative.
Fu: base 20; closed ron 10; non-pinfu tsumo 2; value pair 2 (double wind still 2); pair/closed/edge wait 2. Open pung 2, concealed pung 4; terminals/honors double these and kongs multiply by 4. Round to ten; seven pairs fixed 25, pinfu tsumo fixed 20.
Base B = fu × 2^(han+2), normally capped at 2000; 1920 rounds up to mangan 2000. 5 han: 2000; 6–7: 3000; 8–10: 4000; 11–12: 6000; 13+: 8000. Each yakuman contributes 8000, with stacking but no special-wait double yakuman.
Round each payment up to 100. Non-dealer ron 4B, dealer ron 6B. Non-dealer tsumo: dealer 2B, others B; dealer tsumo: all 2B. Each honba adds 100 per tsumo payer or 300 on ron; each deposit gives winner 1000. Liability can be set for big dragons, big winds or four kongs. Furiten blocks ron.
