LRC Taiwanese scoring, worked through

Find the hand value, then the payments.

Under the Mahjong app’s LRC Taiwanese rules, a winning hand’s value is the sum of its awarded scoring elements plus a five-point base. On a discard win, the discarder pays that value once. On a self-draw, each of the three opponents pays it.

This guide follows the December 2024 LRC publication as implemented by Mahjong. It uses points, not a generic tai or fan conversion. Related scoring patterns can replace one another, and immediate payments are recorded separately.

New to the structure? Start with the Taiwanese rules introduction. The examples below show why the same tiles can produce different totals.

One layout, three ways to finish.

South is the winner and East is the dealer. The 1–2–3 Bamboo sheung is already exposed; the remaining sets stay concealed until the win. Before winning, South holds 5–6 Circles and can finish that sequence with a 4 or a 7. In every example, the winning tile is the 7.

South’s flower number is 2. Red 1 and Blue 3 are therefore off-seat flowers and receive no seat-flower bonus. The East pair is a pair, not a wind pong. The hand spans all three suits and contains honours, so neither a suit-hand award nor a no-honours award applies.

Assumptions for all three examples: ordinary late-hand play, no early-win award, no calling declaration or special wait, no gong or replacement draw, no dealer involvement in the win, no dealer streak addition, no carried pot, and no immediate payments. The exposed sheung prevents a concealed-hand award. These are worked examples, not a complete scoring table.

One flower: a 25-point Chicken Hand

Flowers: Red 1. Winning tile: West discards the 7 of Circles.

The off-seat flower supplies one ordinary point. With no special hand and no other qualifying points, the Chicken rule replaces that one point with 20. Add the five-point base: 25, not 26.

Two flowers: a 7-point discard win

Flowers: Red 1 and Blue 3. Winning tile: West discards the 7 of Circles.

Two off-seat flowers supply two points. The Chicken condition of exactly one ordinary point no longer applies. Two flower points plus the five-point base make seven. Adding a flower can therefore produce a lower total in this particular ruleset.

The same two flowers: an 8-point self-draw

Flowers: Red 1 and Blue 3. Winning tile: South draws the 7 of Circles from the ordinary live wall.

Keep the same exposed set and two flowers. Drawing the winning tile from the ordinary wall adds one point: two for flowers, one for self-draw, and five base. Each opponent pays the full eight points, so South receives 24.

Check what changed before recording.

Count physical tiles carefully: a gong occupies one set but contains four tiles, and flowers sit outside the winning structure. Record exposed sets, bonus flowers, the actual winning tile, who discarded it, and whether the draw came from the live wall or flower wall.

Do not add an immediate flower-set or concealed-gong payment to the hand value a second time. If the app requests a choice of tile arrangement or a rule confirmation, resolve it before applying the score.
