Setting up for Riichi
Riichi scoring depends on more than your tiles — your seat, the round, and which yaku your hand actually contains all change the number at the end. This page walks through everything worth setting correctly before you rely on the app's advice, and explains the reasoning behind it, not just which button to press.
1. Select Riichi as your ruleset
Open the ruleset dropdown in the top bar and choose Riichi. This changes how every score is calculated, and — importantly for this guide — it's one of the five rulesets where Seat Wind and Round Wind actually appear and matter. See Rulesets & Custom Hands for how Riichi compares to the app's other scoring systems.
2. Set your Seat Wind and Round Wind
Two dropdowns appear in the top bar once Riichi is selected. Both feed directly into Rack Analyst, Board Evaluator, and Live Co-Pilot's advice — not just Table Scorer's final score.
| Setting | What it means |
|---|---|
| Seat Wind | The wind matching your own seat at the table — East, South, West, or North. A triplet of this wind tile is worth 1 han. |
| Round Wind | The wind of the current round being played — East round or South round in a standard Hanchan game. A triplet of this wind is also worth 1 han, separately. |
These stack. If a wind tile happens to match both your seat and the round — for example, you're sitting East during the East round — a triplet of East is worth 2 han, not 1. The app accounts for this automatically once both are set correctly; a triplet of a wind matching neither is just an ordinary tile with no bonus value at all.
Rack Analyst, Board Evaluator, and Live Co-Pilot each show an amber Seat Wind not set badge in their panel until you set it. This isn't cosmetic — without it, the app has no way to know whether a wind tile in your hand is worth keeping for its yaku value or safe to discard as an ordinary tile.
3. Let Round Wind track itself, if you're playing a full game
If you're using Score Sheet to track an entire session, choose Tonpuusen (East round only) or Hanchan (East round, then South round) there. Round Wind then advances on its own as the deal genuinely rotates — a dealer repeat never counts as progress, the same as at a real table, so the round only moves forward after an actual change of dealer.
This is shared app-wide: the moment Score Sheet flips Round Wind from East to South, Rack Analyst, Board Evaluator, and Live Co-Pilot all see the update immediately. You never need to set it in two places.
Not tracking a full session? The Round Wind dropdown in the header still works as a plain manual setting at any time — set it once at the start of a hand and leave it.
4. Dora indicators
Under the Dora Indicators section, add up to five indicator tiles as they're revealed during play. Each dora indicator points to the tile actually worth the bonus — for example, an indicator of 3 of Circles means 4 of Circles is the dora, worth an extra han for every copy held. Rack Analyst and Live Co-Pilot factor this into which tiles are worth keeping, the same way they factor in wind.
5. How each part of the app uses this
Rack Analyst & Board Evaluator
A wind tile matching your seat, the round, or both is weighted as more worth keeping than an equivalent non-matching tile — the app is quietly doing the han-counting for you before it ever suggests a discard.
Live Co-Pilot
The same wind-value reasoning applies turn by turn, and stays current automatically if Round Wind is being auto-advanced by Score Sheet mid-session.
Table Scorer
Points Calculator's Riichi mode uses your Seat Wind and Round Wind for the actual han/fu payment calculation — the numbers that determine who pays what.
Score Sheet
Owns the Tonpuusen/Hanchan tracking described above, and shows a quiet completion banner once the round structure finishes.
Quick yaku reference
A short list of common Riichi yaku, for reference while you're setting up a hand — not exhaustive, but enough to sanity-check what the app is suggesting.
| Yaku | Han | Condition |
|---|---|---|
| Riichi | 1 | Closed hand, declared before your first discard after tenpai. |
| Tanyao | 1 | No terminal (1 or 9) or honor tiles anywhere in the hand. |
| Pinfu | 1 | All sequences, a valueless pair, and a two-sided wait. |
| Menzen Tsumo | 1 | Won by self-draw with a fully concealed hand. |
| Yakuhai | 1 each | A triplet of a dragon, your seat wind, or the round wind. |
| Honitsu | 2–3 | One suit plus honor tiles only. |
| Chinitsu | 5–6 | One suit only, no honor tiles. |
Han values above are for a standard closed hand — several of these are worth less if your hand is open (melds called from other players). See Table Scorer for how the app calculates a full score once a hand is complete.
