From poker to riichi

You already have most of the skills riichi rewards: hand reading, position, pot control, folding, variance management. What's new is the vocabulary — and two instincts that need retuning. This page maps what you know onto its riichi equivalent, honestly, including where each analogy breaks.

Yaku are hand rankings you build toward

In poker, hand rankings just happen — you bet on whatever the board makes of your cards. Riichi's equivalent is yaku 役: a fixed list of scoring patterns, and your hand must contain at least one to be allowed to win at all. The difference is direction. Rankings happen to you; yaku are chosen and built. From your first discard you are steering thirteen tiles toward a pattern, and the pattern you pick decides your speed and your payout. Browse the yaku list the way you once memorized rankings — but expect to plan toward them, not merely recognize them.

The dealer is the button, but louder

Position is real here too. Each hand, one player is the dealer, and dealer wins score 1.5 times what the same hand would pay a non-dealer. Better: a dealer who wins keeps the deal and plays another hand with the same bonus. So dealership works like the button — a rotating positional edge — except the edge compounds for as long as you can hold it, and it ends when someone else wins — or when a drawn hand finds the dealer not ready (noten). When you are dealer, that changes the math on pushing; when an opponent is a repeating dealer, ending their run has value beyond the single hand. The numbers live in the scoring section.

Riichi is a committed bet that talks

When your closed hand is one tile from complete, you may stake 1,000 points and declare riichi. From that moment the hand is locked: you draw, and you either win or discard the drawn tile. Almost no more decisions (the rare exceptions live in the riichi lesson). In exchange you get an extra han, access to hidden bonus tiles if you win, and real pressure on the table. That is an all-in in the sense that matters — you trade every remaining decision for maximum value. And like an all-in, it broadcasts information: everyone now knows you are one tile from winning, and every discard you make afterward is forced and public. The mechanics are in the riichi lesson.

Damaten is slow-playing

The quiet counterpart: damaten ダマテン, staying silent while one tile from a win. Nobody tenses up, nobody starts folding around you, and you catch tiles people still believe are safe. The cost is exactly slow-playing's cost — you give up value (the riichi han and its bonuses) to keep deception. Poker players tend to find the right damaten spots faster than anyone else at the table, because the trade-off is one you have priced a thousand times.

Folding exists, and it wins

The biggest myth to kill: riichi is not a race where everyone pushes to the end. When an opponent declares riichi and your own hand is cheap or far from ready, the strong play is usually to fold — stop building, and spend every turn discarding the safest tiles you have. The bedrock safe tile is genbutsu 現物: any tile an opponent has already discarded cannot lose to that player's ron — a certainty enforced by the furiten rule. Think of defense as pot control where some folds carry zero risk against one opponent. Over a full game, the points you refuse to give away count exactly as much as the points you win.

Dora is board volatility

Every hand, one tile type is designated as a bonus — an indicator tile points to it, as covered in the setup lesson — and each copy of that dora ドラ tile in a winning hand adds a han. Dora is not a yaku — it never makes a hand legal, it makes legal hands bigger. Functionally it is the wet board: the same structure can be cheap or expensive depending on cards nobody controls. Red five tiles work the same way, and a riichi win flips additional hidden dora — one more reason the declaration carries weight.

Bankroll thinking is point management

Your points are a stack carried through the whole game, and first place is decided by the final count, not by hands won. That makes variance discipline transfer directly. A standard game runs an East round and then a South round; when you reach the South round with a lead, tighten up — fold hands you would have pushed earlier, take small safe wins, and make opponents pay full price for the chance to catch you. You do not need to win the last pot to win the session. Same logic, same discipline, and the players who lack it lose leads here the same way they do at a cash table.

Tells live in the discards, not faces

No sunglasses required. Every player's discards sit face up, in order, in front of them — a complete public betting history for the hand. Early honor tiles read like a standard hand developing; a middle number tile discarded suddenly after many turns often means a plan changed. Reading discard rows is riichi's version of reading a betting line, and you learn it the same way: one pattern at a time, starting with how turns and discards work.

Two poker instincts that will cost you

• Playing every hand. There is no ante decision — you are dealt into every hand automatically, and the instinct is to make something of each one. Resist it. Many starting hands are not worth pushing to the end, and giving up early is a skill riichi pays for every bit as reliably as poker pays tight preflop play. Fold more than feels natural.
• Equating aggression with pressure. In poker, aggression wins pots by itself. A riichi declared on a bad wait or a cheap hand applies pressure but pays for it: you hand the table information and lock your hand for small value. Riichi is selective aggression — declare when the wait and the payout justify it, stay damaten or fold when they don't.
