|| Kokushi scored on a jigoku 1m ron. Haipai consisted of 10 unique yaochuuhai, including every honor tile. Thus, kyushu kyuhai was declined and a yakuman was attempted from the beginning. Immediately after tenpai was achieved, shimocha dealt the final winning tile.
|| Kokushi scored ron on the west tile. Haipai consisted of 11 yaochuuhai, 10 unique. Tenpai was achieved on the ninth self-draw, in the first half of the second row. Immediately afterwards, toimen decided to lose 48k.
|| Suuankou scored via 8p tsumo on a shanpon 4m/8p wait. Tenpai was achieved fairly early. There was no concrete decision to go for suuankou, the hand just built itself this time around. Dora toitsu meant ron would have been taken, but luckily it ended up not mattering too much.
|| Shousuushii scored ron on the East. Starting haipai consisted of 7 winds. Honitsu chanta tenpai was achieved on the seventh draw, but was declined to pursue yakuman. Hand was pushed against a possible opposing Daisangen. Game was played as a guest on Tenhou.
|| Daisangen scored ron on the Hatsu. Starting haipai consisted of two of each sangenpai. Tenpai was achieved at the end of the first row, and kamicha dealt the winning tile two turns later. Game was played as part of club play for Chicago Area Mahjong.
