Mahjong Scoring Basics
A riichi win is a han count and a fu count. Han comes from yaku. Fu comes from the melds, the pair, the wait, and whether the win was a ron or a tsumo. Below a limit, base points are fu times 2 raised to the power of han plus 2. The seat and the win method turn those base points into a payment, and each payment rounds up to the next 100. At mangan and above, a fixed row replaces the product.
This page is that path. The worked hands are East round, South seat, so the winner is a non-dealer unless a sentence moves the same hand to the East seat. East is the round wind. South is the seat wind. West and North are guest winds. No caption includes dora, honba, or riichi sticks. Counting Han, Fu Calculation Basics, and the Score Table are the three references. Riichi Mahjong is the rules frame around them.
Score training gives the yaku and the seat. You enter fu, han, and the payment. The drill stops before dora, honba, and riichi sticks, so the number you enter is this core payment.
Han is the floor
No yaku means no win. A hand can be tenpai, with a clear wait and a clear fu total, and still pay nothing on a ron until a yaku exists. A closed self-draw can supply that yaku by itself: menzen tsumo is 1 han. A riichi declaration is also 1 han, and it has to be made while the hand is closed. Dora, red fives, and ura dora add han after a yaku is already there. They do not open the floor.
Han from different yaku adds. Yakuman names replace the sum rather than sitting on top of it. The same tiles can also change han when a different winning tile completes a different pattern. Fu does not move the floor. A 40 fu hand with no yaku is still a miss.
Complete. Shanten −1. Sequences of 234 man, 567 man, 456 pin, and 678 sou, pair of 8 sou. Every tile is 2 through 8, so tanyao is 1 han. That han is the tile set. No dora is inside it.
The finished groups are four sequences and a pair. Pinfu is a second han only when the wait that completed a sequence was two-sided and the pair is not a value pair. This picture does not mark which tile arrived, so the locked claim is tanyao. The tanyao page is the simples test. The yaku guide is the rest of the list.
Shanten 0. Waits 5 sou ×4 and 8 sou ×2: 2 kinds, 6 tiles. Sequences of 234 man, 567 man, and 345 pin, with 67 sou and a pair of 8 sou. Both tiles finish a two-sided wait. Tanyao and pinfu are already available. A closed ron is 2 han at 30 fu.
Two copies of 8 sou are already in the pair, so that side has 2 tiles left. No 5 sou is in the hand, so that side has 4. The fu row does not care about that split. Ryanmen is 0 either way, and a non-value pair of 8 sou adds nothing. Closed ron is the base 20 plus 10, which is the pinfu total of 30. Child ron at 2 han 30 fu is 2000. Dealer ron is 2900. Those payments are worked below.
Complete. Shanten −1. White triplet, sequences of 234 man, 456 pin, and 789 sou, three 9 sou. White is yakuhai for 1 han. The triplet is closed, 8 fu. A closed ron rounds to 40 fu. Child ron is 1300. Dealer ron is 2000.
Shanten 0. Waits 6 sou ×4 and 9 sou ×2: 2 kinds, 6 tiles. The white triplet is already in the hand, so the yaku and the 8 fu are there before the win. Either tile keeps 1 han at 40 fu.
The tenpai shape is 78 sou beside a pair of 9 sou. Winning on 6 sou is only a two-sided completion: 678 sou, pair unchanged, wait fu 0. Winning on 9 sou can be read as that same two-sided completion or as a pair wait. Fu before the wait is 20 + 10 + 8 = 38, which already rounds to 40. Adding the tanki 2 lands on 40 as well. The payment does not move. What the dragon contributes is the han, plus the 8 that pushed the unrounded total off 30.
Shanten 0. Waits 6 sou ×4 and 9 sou ×2: 2 kinds, 6 tiles. 112233 man is 123 twice, which is iipeikou. The sou wait is two-sided, and the pair of 9 sou is not a value pair, so pinfu stacks. Closed ron is 2 han at 30 fu. Child ron is 2000. Dealer ron is 2900.
One man blocks tanyao. On 9 sou, a tanki reading would drop pinfu and leave iipeikou alone at 40 fu, a child ron of 1300. The higher score keeps the two-sided reading, the pinfu, and 2000. When two decompositions both win, use the one with the higher payment. Iipeikou and pinfu are the two names in that higher line.
Shanten 0. Waits 2 sou ×4 and 5 sou ×4: 2 kinds, 8 tiles. 345 man and 345 pin are set. 34 sou is two-sided. Only 5 sou makes 345 sou and scores sanshoku. The red pair is 2 fu and is not a yaku.
Closed sanshoku is 2 han. The red pair blocks pinfu, and an honor is not tanyao. Fu on the 5 sou ron is 20 + 10 + 2 = 32, which rounds to 40. Two han at 40 fu: base points 640, child ron 2600, dealer ron 3900. The 2 sou wait makes 234 sou. That is not sanshoku, and the hand has no other pattern yaku, so a ron on 2 sou does not pay. Same tenpai, two different han totals. Sanshoku is the three-suit test, and it cares which tile arrived.
Shanten 0. Waits 3 man ×3, 6 man ×3, and 9 man ×4: 3 kinds, 10 tiles. The pair is 9 sou. All three sides are two-sided sequence waits, so pinfu applies. Ittsu is only the 9 man, which completes 789 man beside 123 and 456. That side is 3 han at 30 fu, child ron 3900. The 3 man and 6 man sides are pinfu only, 1 han at 30 fu, child ron 1000.
Closed ittsu is 2 han and stacks with pinfu. One man and the 9 sou block tanyao. Dealer ron on the 9 man is 5800. Dealer ron on the 3 man or the 6 man is 1500. The wide wait is real, and two of the three tiles are a different score.
Shanten 0. Shanpon on 1 pin ×2 and 9 sou ×2: 2 kinds, 4 tiles. 123 man, 789 man, and the East triplet each include a terminal or an honor, and either pair that remains is a terminal. Closed chanta is 2 han. East is the round wind, so the triplet is also yakuhai. A ron on either tile is 3 han at 50 fu. Child ron is 6400. Dealer ron is 9600.
The wait itself is shanpon, 0 fu. The triplet the discard completes is scored as open: a terminal is 4 fu, not the closed 8. East stays closed because the win was not East, so East is 8 fu. The pair that remains is a plain terminal, 0 fu. The total is 20 + 10 + 8 + 4 = 42, which rounds to 50. Three han at 50 fu has base points 1600. The sequences keep this out of toitoi. The East honor keeps it out of junchan, which wants terminals only. Chanta and yakuhai are the two han sources. At a seat where East matches neither the round nor the seat, the triplet still scores 8 fu and scores no han, and the hand is chanta only, 2 han at 50 fu, child ron 3200.
Fu is the shape
Every ordinary hand starts at 20 fu. Add the rows that apply, then round up to the next 10. A total that is already a multiple of 10 stays there. 32 becomes 40. 38 becomes 40. 42 becomes 50. 24 becomes 30.
| Source | Fu |
|---|---|
| Base | 20 |
| Closed ron | +10 |
| Tsumo | +2, except pinfu tsumo and chiitoitsu |
| Open triplet, simple (2–8) | +2 |
| Open triplet, terminal or honor | +4 |
| Closed triplet, simple | +4 |
| Closed triplet, terminal or honor | +8 |
| Open kan, simple | +8 |
| Open kan, terminal or honor | +16 |
| Closed kan, simple | +16 |
| Closed kan, terminal or honor | +32 |
| Dragon pair, seat-wind pair, or round-wind pair | +2 |
| Pair that is both seat wind and round wind | +4 |
| Tanki, kanchan, or penchan | +2 |
| Ryanmen or shanpon | +0 |
A triplet completed by the ron tile is scored on the open row, even when the hand never called. A triplet completed by tsumo, or already closed in the hand, stays on the closed row. Sequences are 0. A guest-wind pair is 0. A terminal pair is 0 unless that wind is the seat or the round. An open hand whose only fu would be the base 20 is scored as 30. None of the hands below are open, and none contain a kan. The kan rows are here so a closed kan is not priced as a triplet. The full component list is also on the fu page. Wait names are on Wait Types.
Two exceptions skip the table. Chiitoitsu is 25 fu on a ron and on a tsumo. Nothing in the table adds to 25, and 25 does not round to 30. Pinfu tsumo is 20 fu. The tsumo 2 is not added, and the total does not round up to 30.
Ryanmen adds 0
A ryanmen is two adjacent tiles with room on both sides, such as 67 waiting on 5 and 8. The winning tile completes a sequence. Fu from the wait is 0. That 0 is also what lets pinfu exist. Pinfu wants four sequences, a pair that is not yakuhai, a closed hand, and this two-sided wait.
Shanten 0. Waits 5 sou ×4 and 8 sou ×2: 2 kinds, 6 tiles. 67 sou beside a pair of 8 sou, with sequences 345 man, 567 pin, and 234 sou. Ryanmen is 0 fu. All simples, so tanyao stacks with pinfu. Closed ron is 2 han at 30 fu.
Shanten 0. Waits 5 man ×4 and 8 man ×2: 2 kinds, 6 tiles. 67 man beside a pair of 8 man, with 234 pin, 567 pin, and 345 sou. Same ryanmen row, same 0 fu, same tanyao and pinfu. Closed ron is again 2 han at 30 fu.
The copy split is the tile count, not a fu bonus. Four tiles on one side and two on the other still add 0. Child ron is 2000 and dealer ron is 2900 for either hand. A tsumo changes the inputs. Pinfu tsumo drops the fu to 20, and menzen tsumo adds 1 han on top of tanyao and pinfu, so the hand becomes 3 han at 20 fu. A child then collects 1300 from the dealer and 700 from each other child. A dealer tsumo collects 1300 from each child.
Kanchan and penchan add 2
A kanchan is a gap in the middle: 57 waits on 6, 68 waits on 7. A penchan is an edge: 12 waits on 3, and 89 would wait on 7. Each is 2 fu. They are not pinfu. After the base 20 and the closed-ron 10, the unrounded total is 32 when nothing else scores, and 32 rounds to 40.
Shanten 0. Waits 6 sou ×4: 1 kind, 4 tiles. 57 sou is the gap, pair of 9 sou, sequences 456 man, 789 man, and 234 pin. Kanchan is 2 fu. Closed-ron fu is 32, which rounds to 40. Nine sou is a terminal, and the wait is not two-sided, so there is no pattern yaku yet.
Shanten 0. Waits 7 sou ×4: 1 kind, 4 tiles. 68 sou is the gap, pair of 9 sou, sequences 345 man, 678 man, and 123 pin. The fu row matches the hand above: 2 from the wait, 32 rounded to 40. One pin and 9 sou block tanyao.
Shanten 0. Waits 3 sou ×4: 1 kind, 4 tiles. 12 sou is the edge, pair of 9 sou, sequences 345 man, 678 man, and 456 pin. Penchan is the same 2 fu as kanchan. Closed-ron fu rounds from 32 to 40.
Shanten 0. Waits 3 sou ×4: 1 kind, 4 tiles. 12 sou again, pair of 9 sou, with 234 man, 567 man, and 456 pin. Same edge, same 2 fu, same 40 after rounding. The man sequences do not add fu.
These four hands show the wait row and nothing else. A ron still needs a yaku. Menzen tsumo would be that yaku at 1 han, and the fu would be 20 + 2 for the tsumo + 2 for the wait = 24, which rounds to 30. A riichi ron would keep the 40 fu and add its own han. The wait does not provide either of those han.
The pair of nines is not always a tanki
Shanten 0. Waits 6 sou ×4 and 9 sou ×2: 2 kinds, 6 tiles. The sou tiles are 7899. The live shape is 78 sou, a ryanmen, beside a pair of 9 sou. Ryanmen is 0 fu. The pair is not a value pair, and the other groups are sequences, so the hand is pinfu. One man and 9 pin block tanyao. Closed ron is 1 han at 30 fu. Child ron is 1000. Dealer ron is 1500.
A pure tanki on 9 sou would wait on 9 sou only. The 6 sou wait is the proof that 78 is two-sided. Only two 9 sou remain because the pair already holds two. That copy count is not tanki fu. Scoring the 9 as a tanki would drop pinfu. With no other pattern yaku, that reading cannot ron. The higher legal score is the ryanmen.
Tied copies can still be tanki fu
Four consecutive tiles, such as 6789, wait on both ends. Each end completes a pair: 66 with 789, or 99 with 678. The shape is a nobetan, two tanki waits sharing one block. Each side scores the tanki 2. The copy counts can match, which is why the block gets filed under ryanmen. The fu row is still the tanki row.
Shanten 0. Waits 6 man ×3 and 9 man ×3: 2 kinds, 6 tiles. 6789 man is the block, with sequences 234 man, 456 pin, and 789 sou. Either tile completes a pair, so the wait is tanki, 2 fu. Closed-ron fu is 32, which rounds to 40. Nine man and 9 sou are terminals, and the wait is not ryanmen, so there is no pattern yaku.
One 6 man and one 9 man are already in the block, so each side has 3 left. A true ryanmen with a pair already chosen, like the 67 sou hands above, does not need the winning tile to become the pair. This one does. Filing it as 0 fu understates the closed ron by a bracket once a yaku is present: 30 fu instead of 40.
Triplets and the value pair
A closed simple triplet is 4 fu. A closed terminal or honor triplet is 8. The pair is a separate 2, and only for a dragon, the seat wind, or the round wind. A dragon pair is not yakuhai. Yakuhai is the triplet. The pair still pays the 2.
Shanten 0. Waits 3 pin ×4 and 6 pin ×4: 2 kinds, 8 tiles. 45 pin is ryanmen, 0 fu. 111 man is a closed terminal triplet, 8 fu. 333 man is a closed simple triplet, 4 fu. The white pair is 2 fu and is not a han. 789 sou is a sequence. Closed-ron fu is 20 + 10 + 8 + 4 + 2 = 44, which rounds to 50. The pattern list is empty until a yaku is added.
The winning tile completes a sequence, so both triplets stay closed. With one han on top, 1 han at 50 fu pays a child ron of 1600 and a dealer ron of 2400. The white pair does not supply that han.
Shanten 0. Shanpon on 1 pin ×2 and red ×2: 2 kinds, 4 tiles. 111 man and 999 man are closed terminal triplets, 8 fu each. The wait is 0 fu. A ron on red makes an open honor triplet, 4 fu, and scores yakuhai. The pair left behind is 1 pin, 0 fu. Total 50. One han at 50 fu, child ron 1600. A ron on 1 pin makes an open terminal triplet, 4 fu, leaves the red pair at 2 fu, and totals 52, which rounds to 60. That side has no pattern yaku, because red is still a pair.
Shanpon adds no wait fu, and it still changes the bill. The tile you catch is priced as the triplet it becomes. On a ron that triplet is open. On a tsumo it is closed, and a third closed triplet would be sanankou. The 1 pin ron is the high-fu side and still cannot be declared until a yaku exists. The red ron is the side that already has yakuhai.
Chiitoitsu is 25, exactly
Seven distinct pairs, closed, is chiitoitsu: 2 han, and the fu is 25. The tanki that every seven-pair hand waits on does not add 2. A dragon pair does not add 2. Closed ron does not add 10. The total does not round to 30. Four of a kind is not two pairs. A hand that can be read as four melds and a pair is not this yaku.
Complete. Shanten −1. Pairs of 1 man, 2 man, 3 man, 4 pin, 5 pin, 6 pin, and 8 sou. Seven distinct pairs. One man blocks tanyao, so the han is 2 and the fu is 25. Base points are 25 × 16 = 400. Child ron is 1600. Dealer ron is 2400.
The arithmetic is the whole point of the fixed 25. Two han uses 2^(2+2), which is 16. 25 × 16 = 400, and 400 × 4 = 1600 with nothing to round. The same 2 han at the pinfu fu of 30 is a child ron of 2000, because 30 × 16 = 480 and 480 × 4 = 1920, which rounds up to 2000. Chiitoitsu pays less at the same han because the fu is 25.
1600 is easy to misfile. The child ron of 6400 is 4 han at 25 fu, and it is also 3 han at 50 fu. Adding a second multiplier, as if 1600 were the base, produces that 6400 from a hand that does not have it. A tanyao stack is the legal way to move this shape: seven pairs of 2 through 8 are 3 han at 25 fu, and the child ron is 3200. This hand has a 1 man, so it stays at 1600.
Shanten 0. Waits 8 sou ×3: 1 kind, 3 tiles. Six pairs are already made, and one 8 sou is the tanki. The win is the same 2 han at 25 fu as the completed hand. The tanki does not become 27, and it does not round to 30.
Shanten 0. Waits 7 man ×3: 1 kind, 3 tiles. Pairs of 1 man, 2 pin, 3 sou, 4 man, 5 pin, and 6 sou, one 7 man short of the seventh pair. One man blocks tanyao. The finished hand is again 2 han at 25 fu, child ron 1600.
A standard meld hand with a one-tile tanki does the opposite with that 2. It adds the 2, then rounds. The next section uses that hand as the dealer contrast. Seven pairs never take that path.
Base points, then the round to 100
Below a limit:
base points = fu × 2^(han+2)
A child ron multiplies by 4. A dealer ron multiplies by 6. Round the payment up to the next 100. Do not round to the nearest 100, and do not round down. 1920 becomes 2000. 2880 becomes 2900. 960 becomes 1000.
The cells these hands use:
| Han and fu | Raw base | Child ron | Dealer ron |
|---|---|---|---|
| 1 han 30 fu | 240 | 1000 | 1500 |
| 1 han 40 fu | 320 | 1300 | 2000 |
| 1 han 50 fu | 400 | 1600 | 2400 |
| 2 han 25 fu | 400 | 1600 | 2400 |
| 2 han 30 fu | 480 | 2000 | 2900 |
| 2 han 40 fu | 640 | 2600 | 3900 |
| 2 han 50 fu | 800 | 3200 | 4800 |
| 3 han 30 fu | 960 | 3900 | 5800 |
| 3 han 50 fu | 1600 | 6400 | 9600 |
| 4 han 25 fu | 1600 | 6400 | 9600 |
| 4 han 30 fu | 1920 | 7700 | 11600 |
Two han at 25 fu and one han at 50 fu share a payment, 1600 and 2400. The inputs are different. Four han at 25 fu shares 6400 with three han at 50 fu. Read the han and the fu before you memorize the points.
Mangan and the rows above replace this product. The test is in the next section. Four han at 30 fu is still on this table, at 7700 for a child, because 1920 is under the mangan base.
Child, dealer, ron, and tsumo
| Win | Who pays |
|---|---|
| Child ron | The discarder pays base × 4 |
| Dealer ron | The discarder pays base × 6 |
| Child tsumo | Dealer pays base × 2. Each other child pays base × 1 |
| Dealer tsumo | Each of the three children pays base × 2 |
Each payer rounds up alone. That is why a dealer ron and a dealer tsumo at the same han and fu can differ by 100.
Shanten 0. Waits 4 sou ×3 and 7 sou ×3: 2 kinds, 6 tiles. 4567 sou waits on both ends, and each end completes a pair, so the wait is tanki, 2 fu. Sequences 345 man, 678 man, and 234 pin are all simples. Tanyao is 1 han. There is no pinfu. Closed ron is 32 fu, rounded to 40. Base points are 320. Child ron is 1280, which rounds to 1300.
From the East seat the same ron is 320 × 6 = 1920, which rounds to 2000. A tsumo is a different line, not a different multiplier on 1300. Menzen tsumo adds 1 han, and the fu becomes 20 + 2 + 2 = 24, which rounds to 30. That is 2 han at 30 fu. A child collects 1000 from the dealer and 500 from each other child, 2000 in all. A dealer collects 1000 from each child, 3000 in all.
Compare that dealer tsumo with a dealer ron at the same 2 han 30 fu. The ryanmen tanyao-pinfu hands are the ron side of that cell: raw base 480, dealer ron 2880, which rounds to 2900. The dealer tsumo at 2 han 30 fu totals 3000 because each of three payers rounds 960 up to 1000. The discarder on a ron rounds once, from 2880 to 2900. Same han, same fu, two totals.
Shanten 0. Waits 9 man ×3: 1 kind, 3 tiles. Sequences 345 pin, 678 pin, 456 sou, and 234 man, and a single 9 man. The tanki is 2 fu. Nine man blocks tanyao, and a tanki blocks pinfu, so the tiles alone have no yaku. A closed self-draw is menzen tsumo, 1 han, at 24 fu rounded to 30. Child tsumo is 500 from the dealer and 300 from each other child. Dealer tsumo is 500 from each child.
A riichi ron on that same tanki is a different declaration. Riichi is the yaku, the closed-ron 10 replaces the tsumo 2, and the tanki 2 stays. Fu is 32, rounded to 40, at 1 han. Child ron is 1300. Dealer ron is 2000. The +2 from the wait is in both lines. The +10 is only the closed ron. Score training will tell you the seat and whether the win is ron or tsumo. It will not ask you to guess a declaration that the hand does not show.
Shanten 0. Waits 3 pin ×4, 6 pin ×3, and 9 pin ×4: 3 kinds, 11 tiles. 123 man, 789 sou, pair of 9 man, and 45678 pin. Every side completes a sequence on a two-sided wait. Pinfu applies, and the terminals block tanyao. Each side is 1 han at 30 fu. Child ron is 1000. Dealer ron is 1500.
Eleven tiles is the chance of winning. It is not a multiplier. Three kinds at 30 fu pay the same 1000 as the one-kind pinfu ron on the hand that only looked like a tanki. Ukeire belongs to tile efficiency. The score slip reads han, fu, seat, and ron or tsumo.
Mangan and the rows above
Stop using fu × 2^(han+2) when the hand is a limit. Mangan is 5 han at any fu, 4 han at 40 fu or more, or 3 han at 70 fu or more. The mangan base is 2000, so a child ron is 8000 and a dealer ron is 12000. Two han stays on the formula. Four han at 30 fu also stays on the formula: raw base 1920, child ron 7700, dealer ron 11600. Three han at 60 fu is that same 7700 and 11600. Some house rules, called kiriage mangan, bump those two cells up to mangan. This page does not.
| Limit | When | Child ron | Dealer ron | Child tsumo | Dealer tsumo |
|---|---|---|---|---|---|
| Mangan | 5 han, or 4 han at 40+ fu, or 3 han at 70+ fu | 8000 | 12000 | 4000 / 2000 | 4000 |
| Haneman | 6–7 han | 12000 | 18000 | 6000 / 3000 | 6000 |
| Baiman | 8–10 han | 16000 | 24000 | 8000 / 4000 | 8000 |
| Sanbaiman | 11–12 han | 24000 | 36000 | 12000 / 6000 | 12000 |
| Yakuman | 13+ han, or a yakuman yaku | 32000 | 48000 | 16000 / 8000 | 16000 |
| Double yakuman | Where the rules double the yakuman | 64000 | 96000 | 32000 / 16000 | 32000 |
Child tsumo is written as dealer payment, then each other child. Dealer tsumo is the amount from each child. Fu is not read on these rows.
Shanten 0. Waits 3 man ×3, 6 man ×3, and 9 man ×2: 3 kinds, 8 tiles. The white triplet is closed, 8 fu, and it is yakuhai. The rest is man, so the hand is honitsu. Closed honitsu is 3 han. With the dragon, every side is at least 4 han. Fu is 20 + 10 + 8 = 38, which rounds to 40. Four han at 40 fu is a mangan. Child ron is 8000.
The dragon triplet is 1 han, and its 8 fu is what crosses the line. Without that 8 the closed ron would be 30 fu, and 4 han at 30 fu is 7700, still under mangan. Rounding 38 up to 40 is the step that reaches 8000. The 9 man side also completes 123, 456, and 789, so ittsu adds 2 han. Six han is a haneman. Child ron is 12000. The 3 man and 6 man sides do not make 789, and they stay on the mangan row. Two 9 man are already in the pair, which is why that side has 2 copies left rather than 4.
Shanten 0. Shanpon on white ×2 and green ×2: 2 kinds, 4 tiles. Closed triplets: 1 man is 8 fu, 2 pin and 3 sou are 4 each. A ron on either dragon scores that dragon as an open honor triplet, 4 fu, and leaves the other dragon as a pair, 2 fu. The wait is 0. The sum is 20 + 10 + 8 + 4 + 4 + 4 + 2 = 52, which rounds to 60. Han is toitoi 2, sanankou 2, and yakuhai 1. Five han is a mangan. Child ron is 8000. The 60 fu stays inside that row.
A tsumo on either dragon makes the fourth triplet concealed. Four concealed triplets is suuankou, a yakuman, so the mangan row is the wrong row. From the South seat the dealer pays 16000 and each other child pays 8000. The ron does not score suuankou, because a shanpon triplet that arrives from a discard is open. Toitoi and sanankou are the han inside that ron. On the tsumo they are not added on top of suuankou.
Shanten 0. Waits green ×3: 1 kind, 3 tiles. Triplets of 1 man, 2 pin, 3 sou, and white are already closed. The single green is a tanki. Closed-ron fu would be 20 + 10 + 8 + 4 + 4 + 8, plus 2 for the green pair and 2 for the tanki, which is 58 and rounds to 60. Stopping at toitoi, sanankou, and white is 5 han, a mangan. Four concealed triplets with a pair wait is suuankou.
The pair-wait form is a double yakuman at tables that double it, and a single yakuman at tables that do not. Child ron is 64000 or 32000 on that split. The fu total is real arithmetic and it is not the payment. A shanpon suuankou, like the hand above, needs the tsumo. This tanki can be a ron, because every triplet was concealed before the winning tile arrived.
Shanten 0. Nine-sided wait on 1 through 9 pin: 9 kinds, 23 tiles. One pin and 9 pin have 1 copy left. Each of 2 through 8 pin has 3. The pattern is 1112345678999 in one suit, which is nine gates, a yakuman. The nine-sided wait is the pure form.
Tables that score a double yakuman pay a child ron of 64000 for the pure nine-sided wait. Tables that keep every nine-gates win at one yakuman pay 32000. Chinitsu on a closed pin hand would have been 6 han, a haneman, child ron 12000. That is the formula row, and nine gates does not use it. Fu is not read. Count the nine kinds before you call the hand a flush and stop.
Dora, honba, and riichi sticks
The core payment is what score training asks for. A live riichi table adds three things the drill leaves out.
Dora adds 1 han per dora tile in the hand. Red fives, kan dora, and ura dora after a riichi are further han of the same kind. Dora is not a yaku. The tanyao hand at the top of this page is 1 han with no dora in that count. A dora on one of those tiles would raise the han and could move a limit, and it would still not be the reason the hand is allowed to win.
Honba is the repeat counter. On a ron, the discarder pays 300 extra per honba. On a tsumo, each of the three payers pays 100 extra per honba. The dealer does not pay a doubled honba. The counter rises when the dealer repeats, and it is not a han and not a fu.
Riichi sticks are 1000 each. The winner takes every stick on the table, on a ron and on a tsumo. The pot is not split among the payers, and it is not inside base points. Score training does not show a stick count, so the payment you enter has none of that 1000.

What to study next
- Name the yaku in Counting Han until the floor and the stacks are automatic.
- Add fu from the table in Fu Calculation Basics, including the wait and the rounding to 10.
- Check the wait name in Wait Types before you add 2. Ryanmen and shanpon stay at 0. A nobetan does not.
- Read the cell on the Score Table, or multiply and round. Use a limit row when the hand qualifies.
- Enter fu, han, and the payment in score training. The yaku and the seat are given. Dora, honba, and riichi sticks are not.
