Riichi yaku list

How to read this list

• Closed means no tile was called for a group. A concealed kan does not open the hand.
• "Open 1" means the yaku is worth one han less when the hand is open. "Closed only" means it cannot be scored with any called group.
• Dora add han but are not yaku, so a hand with only dora cannot win.
• In the examples, groups that were called are underlined in orange and the winning tile has a gold outline.

All yaku at a glance

1 han yaku

Riichi · 1 han (closed only)

Declare riichi when your closed hand is one tile from winning, pay a 1,000-point stick, and keep playing without changing the hand.

Ippatsu (one shot) · 1 han (closed only)

Win within one go-round after declaring riichi, before your own next discard, with no calls or kans in between.

Menzen tsumo (closed self-draw) · 1 han (closed only)

Win by drawing the last tile yourself while your hand has no melded groups.

Pinfu (no-points hand) · 1 han (closed only)

Four sequences and a pair that is not worth fu, won on a two-sided wait. The hand earns no extra fu at all.

Iipeikou (pure double sequence) · 1 han (closed only)

Two identical sequences in the same suit, in a closed hand.

Tanyao (all simples) · 1 han

Every tile is a number from 2 to 8: no terminals and no honours. It counts on an open hand too.

Yakuhai (value tiles) · 1 han

A triplet or kan of a dragon, of your seat wind, or of the round wind. Each one is worth 1 han, and a wind that is both seat and round wind is worth 2.

Chankan (robbing a kan) · 1 han

Win on the tile another player adds to a pung to make a kan. A concealed kan can never be robbed.

Rinshan kaihou (after a kan) · 1 han

Win on the replacement tile you draw after declaring a kan. It counts as a self-draw.

Haitei (last-tile draw) · 1 han

Win by self-draw on the very last tile of the live wall.

Houtei (last discard) · 1 han

Win on the tile discarded right after the last tile of the live wall was drawn.

2 han yaku

Double riichi · 2 han (closed only)

Declare riichi on your very first discard, with no calls before it. It replaces ordinary riichi.

Chiitoitsu (seven pairs) · 2 han (closed only)

Seven different pairs. Four of the same tile do not make two pairs. The hand is always worth 25 fu.

Ittsuu (pure straight) · 2 han (open 1)

The sequences 1-2-3, 4-5-6 and 7-8-9 all in one suit. One han less when open.

Sanshoku doujun (mixed sequences) · 2 han (open 1)

The same sequence in all three suits, for example 3-4-5 in Bamboo, Dots and Characters. One han less when open.

Sanshoku doukou (mixed triplets) · 2 han

The same triplet in all three suits, for example three 3s in each suit.

Toitoi (all triplets) · 2 han

Four triplets or kans and a pair, with no sequences.

San'ankou (three concealed triplets) · 2 han

Three triplets or kans that you made without calling a tile. A triplet finished by a winning discard counts as open.

Sankantsu (three kans) · 2 han

Three kans in one hand.

Chanta (outside hand) · 2 han (open 1)

Every group and the pair contains a terminal or an honour. It needs at least one sequence and at least one honour. One han less when open.

Honroutou (all terminals and honours) · 2 han

Only terminals and honours, with at least one of each. It always comes with all triplets or seven pairs, so it adds 2 han on top of those.

Shousangen (little three dragons) · 2 han

Two dragon triplets and a pair of the third dragon. The two triplets also count as yakuhai, so the hand is worth at least 4 han.

3 han yaku

Ryanpeikou (two double sequences) · 3 han (closed only)

Two pairs of identical sequences in a closed hand. It replaces iipeikou.

Hon'itsu (half flush) · 3 han (open 2)

Tiles of one suit plus honours, with at least one of each. One han less when open.

Junchan (fully outside hand) · 3 han (open 2)

5 han yaku

Renhou (blessing of man) · 5 han (closed only)

A non-dealer wins on a discard before their own first draw, with no calls made before. It is worth a mangan and does not combine with anything else.

Chin'itsu (full flush) · 6 han (open 5)

Every tile is from one suit, with no honours. One han less when open.

Yakuman

Tenhou (blessing of heaven) · Yakuman
