Multiple yakuman/Replays

Only a limited number of yakuman may combine to produce higher scoring hands than regular yakuman. This is only assuming the rules allow multiple yakuman in the first place.

Double yakuman

09-24-2014	Player: すずめクレイジー	Rank: 天鳳位	Round: 南 1 局 0 本場
Haipai	Draw:
Agari	Ron (Toimen):
Source (Tenhou.net)	A haipai with four honor pairs. The west became an ankou before any tile calls, which made it even easier to complete. Toimen discarded Nan as genbutsu against shimocha riichi.

2015-03-22	Player: チソポ	Rank: 二段	Round: 東 1 局 1 本場
Haipai	Draw:
Agari	Tsumo:
Source (Tenhou.net)	Starting with only 4 winds, pushed quickly to a honitsu. Drew and kept many winds in the process so that, by the time all the pinzu and manzu were out, the hand had 8 winds. After toimen riichi, broke tenpai to hold onto the winds. Shortly after kamicha riichi, completed suuankou daisuushii.

Triple yakuman

2013-11-10	Player: 秘書係	Rank: 四段	Round: 東 4 局 2 本場
Haipai	Draw:
Agari	Tsumo:
Source (Tenhou.net)	Triple yakuman, where the hand was already tenpai for ryanmen for shousuushi. Then the hand was switched to suuankou tanki, when the east pair became a triplet. Finally, a play was made to risk completion of the hand by going to a hell wait with two haku already discarded. The hand was finished anyways.

Rare combinations

02-08-2013	Player: MrZen	Rank: ４級	Round: 東 3 局 0 本場
Haipai	Draw:
Agari	Tsumo:
Source (Tenhou.net)	Chinroutou Suukantsu in a 7447 game. A number of scenarios could have prevented this combination: The player could have declined any tile call, especially the calls for daiminkan. The other players could have withheld the terminals. Any of the tile calls during the hand shifted the draw order. Shimocha had a much faster tenpai and retained a shanpon wait instead of switching to ryanmen, which would have won. Toimen had a winning hand during the 2-pin discard but was furiten. Though, toimen temporarily disconnected. The 8-man discard could have been called for a "fifth kan", but the rules do not allow that. The hand won on the haitei draw.
