Pungs or kongs of all three dragons.

Includes Two Dragons Pungs and Dragon Pung.

Use only bamboo 2,3,4,6,8 and Green Dragon.

Includes Half Flush and One Voided Suit; Full Flush needs separate engine confirmation.

Closed one-suit 1112345678999 base plus one further tile of that suit.

Includes Full Flush, Concealed Hand and the inherent terminal pung; do not infer nine-sided wait from the final shape alone.

Four declared kongs plus a pair.

Includes lesser kong counts, All Pungs and Single Wait; concealed-pung combinations require engine confirmation.

Seven pairs of consecutive ranks in one suit, closed.

Includes Seven Pairs, Full Flush, Concealed Hand and Single Wait.

All six suited terminals and all seven honors, with one of those thirteen faces duplicated, closed.

Includes All Types, Concealed Hand and Single Wait; it does not use four sets and a pair.

Every tile is a wind or dragon.

Includes All Terminals and Honors, All Pungs, Outside Hand, non-value wind pung and One Voided Suit.

Four pungs or kongs formed without claiming their completing tiles.

In one suit, two 123 chows, two 789 chows and a pair of 5s.

Includes Seven Pairs, Full Flush, All Chows, Pure Double Chow, Two Terminal Chows and No Honors.

Four identical chows in the same suit.

Four chows in one suit whose starts rise consistently by one or by two.

Includes the component Pure Shifted Chows, Short Straight and Two Terminal Chows combinations.

Three declared kongs, concealed or melded.

Includes lesser kong-count awards; concealed-pung awards require engine evaluation.

Use only suited terminals and honors, with both categories present.

Includes All Pungs, Outside Hand and terminal/non-value wind pung points.

Every tile is a suited 1,2,3.

Includes Lower Four and No Honors.

123,456,789 chows all in one suit.

Includes Short Straight and Two Terminal Chows from those three sets; independent combinations require engine evaluation.

Includes All Chows, Mixed Double Chow, Two Terminal Chows and No Honors.

Three chows in one suit with starts rising consistently by one or two.

Includes All Simples and No Honors.

Pungs or kongs of the same numbered rank in all three suits.

Includes Double Pung from these sets.

Three pungs or kongs formed without claiming their completing tiles.

Includes Two Concealed Pungs; a discard-completed pung is not concealed for this purpose.

Fourteen distinct tiles chosen from the seven honors and one nine-tile knitted suit assignment, closed.

147 in one suit, 258 in a second and 369 in the third, plus a set and a pair for the ordinary knitted shape.

The nine knitted tiles are not ordinary chows. Can also occur within Lesser Honors and Knitted Tiles; wait awards depend on the calculator's decomposition.

Every tile is a suited 6,7,8,9.

Includes No Honors; superseded by Upper Tiles when all tiles are 7,8,9.

Every tile is a suited 1,2,3,4.

Includes No Honors; superseded by Lower Tiles when all tiles are 1,2,3.

Pungs or kongs of three different winds.

Includes the three inherent wind-pung points; seat/prevalent wind may still apply.

Includes One Voided Suit.

The same three-rank chow in each of the three suits.

Three pungs or kongs with consecutive ranks, one in each suit.

Not a cross-suit pung; each of the three sets must independently contain identical tiles.

A structurally complete hand with no other non-flower scoring pattern.

Not a fallback for a hand worth 1 through 7 points; the engine must verify the absence of other patterns.

Win by drawing the last ordinary wall tile.

Includes Self-Drawn; distinguish it from Last Tile (fourth visible copy) and kong replacement.

Win on the discard following the last wall draw.

Not the same as Last Tile (fourth visible copy).

Win on the replacement tile drawn for a declared kong.

Includes Self-Drawn; a flower replacement does not qualify merely because it is a replacement.

Win on an opponent's tile added to an exposed pung to make a kong.

In this game only an added kong is robbable; never claim a concealed kong or melded kong as robbery. Do not automatically add Last Tile.

Four pungs or kongs and a pair.

Subsumed by stronger patterns that necessarily contain it; no chows.

One numbered suit plus at least one honor tile.

Not Full Flush; includes One Voided Suit.

Three chows in three different suits with starting ranks increasing by one.

Every chow is internally same-suit; overlapping combination points need engine confirmation.

The hand contains characters, bamboo, dots, winds and dragons.

Flowers do not count as a type; included in honors-and-knitted and Thirteen Orphans patterns.

All four sets are exposed through claims, and a discard completes the pair.

No concealed kong; includes Single Wait and is incompatible with a self-drawn win.

Two declared concealed kongs.

Includes the two individual Concealed Kong awards and their Two Concealed Pungs.

Pungs or kongs of two different dragons.

Includes their Dragon Pung awards; superseded by big/little three dragons.

A terminal chow is 123 or 789; subsumed by all-terminal/honor patterns.

No exposed sets and a self-drawn win; concealed kongs are allowed.

Includes Concealed Hand and Self-Drawn; Four Concealed Pungs handles concealment differently.

Two exposed declared kongs.

Includes the individual Melded Kong awards.

Win on the fourth copy of a face when the other three copies are already exposed publicly.

Own concealed copies do not establish this condition; this is unrelated to wall exhaustion.

A pung or kong of one dragon.

Included in higher dragon-set patterns; a dragon pair gives no Dragon Pung points.

A pung or kong of the round wind, East in this game.

Can combine with Seat Wind when both are East; do not add a generic wind-pung point for the same set.

A pung or kong of the player's seat wind.

Can combine with Prevalent Wind for the same set; a pair is insufficient.

No exposed sets, winning by discard; concealed kongs are permitted.

Discard-completed pung remains exposed for concealed-pung counting. Included in closed special patterns.

Four chows plus a pair of suited tiles.

May be open in MCR; includes No Honors. Do not import riichi pinfu conditions.

All four copies of a face occur in the hand without being a declared kong.

Can include two pairs; Quadruple Chow subsumes its tile hogs.

Two pungs or kongs of equal numbered rank in two suits.

Each pung is internally identical; included in Triple Pung and suppressed for All Terminals by this calculator.

Two pungs or kongs formed without claiming their completing tiles.

Not additive with higher concealed-pung counts; a discard-completed pung is exposed for this count.

Four identical tiles declared as a kong without a claimed completing tile.

Four concealed copies alone are not a kong until declared; higher kong counts supersede component awards.

Every tile is suited and ranked 2 through 8.

Includes No Honors; included in All Even Pungs, All Five and Middle Tiles.

Two identical chows in the same suit.

Included in higher identical-chow combinations; set reuse restrictions apply.

Two chows of the same ranks in different suits.

Included in Mixed Triple Chow; each chow itself must stay within one suit.

Two chows in one suit forming six consecutive ranks.

Included when those sets are components of a higher straight or shifted-chow award.

A 123 chow and a 789 chow in the same suit.

Included when those sets are components of higher straight or terminal-chow awards.

A terminal pung/kong or a non-seat, non-round wind pung/kong.

A dragon uses Dragon Pung instead; higher terminal/honor patterns and value winds suppress the component award.

A kong formed by claiming a discard or adding the fourth tile to an exposed pung.

Not additive with higher kong-count awards for the same kongs.

Exactly one of the three numbered suits is absent, with the other two present.

Included in flush patterns and Reversible Tiles; all-honor hands do not earn it separately.

No winds or dragons occur in the hand.

Included in patterns that already require this, such as Full Flush, All Chows and All Simples.

Only one face completes the hand, filling 12 with 3 or 89 with 7 in the chosen decomposition.

Cannot combine with another wait award; all structural waits must be checked, not just eight-point-qualified waits.

Only one face completes the hand, filling the middle of a same-suit sequence such as 24 with 3.

Cannot combine with another wait award; do not infer uniqueness from a single partial shape.

Only one face completes the hand, completing its pair in the chosen decomposition.

Cannot combine with another wait award; included in Seven Pairs, Thirteen Orphans, Melded Hand and Four Kongs.

The winning tile is drawn from the wall by the winner.

Included in Fully Concealed Hand, Last Tile Draw and Out with Replacement Tile, subject to higher-pattern adjustments.
