'''Kokushi musou''' {{kana|国士無双}}, also simply known as '''kokushi''' or in English as '''thirteen orphans''', is one of the standard [[List of yaku#Yakuman|yakuman]] hands. It is one of the three '''yakuman gosanke''' {{kana|役満御三家}}, or "the three big families of yakuman". This hand is one of the two exceptions of the "[[Mentsu|four tile groups and one pair]]" requirement for [[tenpai]] hands, where the other exception is [[chiitoitsu]]. | '''Kokushi musou''' {{kana|国士無双}}, also simply known as '''kokushi''' or in English as '''thirteen orphans''', is one of the standard [[List of yaku#Yakuman|yakuman]] hands.

In fact, hands for this yakuman involve individual tiles while including a [[pair]]. | ||

On average, a hand ending in [[exhaustive draw]] ends with roughly 16-19 tiles discarded per player, pending any tile calls. Therefore, every player has that many tile draws to work with. For example, if a hand starts with 9 tiles for the yakuman, then it requires 4 [[shanten|tile draws]] searching for specific tiles. Usually, barring unusual circumstances, those tile draws are nonconsecutive. If anything, a number of tile draws will be required to even attain tenpai. With that said, the decision to form a kokushi musou must be a decisive one at the [[haipai|very beginning of the hand]]. | On average, a hand ending in [[exhaustive draw]] ends with roughly 16-19 tiles discarded per player, pending any tile calls.

=== 13-way wait development === | |||
Kokushi musou juusan menmachi is very rare. Out of all random tile draws that result in tenpai for kokushi, the chance of naturally drawing all 13 tiles without a single duplicate is approximately one in 9500 (~0.0106%). The only "consistent" way to achieve the double yakuman is to complete kokushi via tsumo, but discard the pair and hope to complete the hand while in furiten. | |||
