Daburu riichi
Daburu riichi 「ダブル立直」 or 「ダブルリーチ」, or double riichi, is a special case for riichi. In this case, the player's start hand is already at tenpai from the dealt tiles. Naturally, a player has the option to declare riichi upon the first tile draw. No tile call may have interrupted the turn order before the declaration, where applicable. For the dealer, this case would be impossible.
| Type | Yaku |
|---|---|
| Kanji | ダブル立直 or ダブルリーチ |
| English | Double ready |
| Value | 2 han |
| Speed | Immediate |
| Difficulty | At discretion |
Double riichi is worth 2 han instead of 1 han for a normal riichi, as a bonus for the initial timing. With the added han value, a call for double riichi has a huge advantage over the other players in conjunction with the immediate speed of the hand.
