Two sets of identical sequences 二盃口 · ryanpeikou
Two separate pairs of identical sequences in a closed hand.
| Value | 3 han — closed hands only |
|---|---|
| How often | very rare |
Ryanpeikou grows out of a shape you already know: one doubled sequence is iipeikou 一盃口, and a second one lifts the hand from 1 han to 3. In play it often emerges from a chiitoitsu 七対子 plan. If six of your seven pairs line up as two runs of consecutive pairs — 3-3, 4-4, 5-5 in one suit, say — the tiles already form ryanpeikou, and that reading is the one that counts.
Stay closed, without exception. A single chii チー or pon ポン removes the yaku, and there's no open version to fall back on. The shape itself is friendly, though: four sequences and a pair means pinfu 平和 often fits, middle-tile builds pick up tanyao 断幺九, and with both attached you're at 5 han before riichi and dora even enter.
The classic table moment is scoring it as seven pairs. The same fourteen tiles can look like chiitoitsu, but ryanpeikou takes precedence, and that works in your favor: 3 han with regular fu beats chiitoitsu's flat 2 han at 25 fu. One caution: this is a rare hand, so treat it as an upgrade the tiles offer along the way, not a target to force from the deal.
