Afterwards, a new hand starts. While the term "ryuukyoku" is usually used to refer to an exhaustive draw in Japanese, on occasion this may be ambiguous, as the term technically refers to any draw (cf. [[tochuu ryuukyoku]], {{kana|途中流局}}). When ambiguity occurs, it may be referred to as '''tsuujou no ryuukyoku''' {{kana|通常の流局}}, which translates roughly as "usual kind of draw".

Around 15.5% of Tenhou hands in the Houou lobby go to an exhaustive draw due to players immediately [[betaori|abandoning the hand]] when a player declares [[riichi]].<ref>https://pathofhouou.blogspot.com/2019/08/analysis-average-houou-game.html</ref>

Sometimes, the ryuukyoku point exchanges is enough to determine the final position in games, especially in [[oorasu]] (the last hand).

Since strong players often [[betaori|abandon the hand]] after a player declares [[riichi]], the exhaustive draw rate is quite high:
* Around 15.5% of Tenhou hands in the Houou lobby go to an exhaustive draw.<ref>https://pathofhouou.blogspot.com/2019/08/analysis-average-houou-game.html</ref>
* Around 23.5% of [[M League]] games in the 2022-2023 regular season went to an exhaustive draw.<ref>https://web.archive.org/web/20230605101538/https://m-league.jp/stats/?season=L001_S013<br>While the exhaustive draw rate is not displayed, it can be calculated. Since M League uses [[atamahane]] and does not have abortive draws, so <code>(average win rate * 4) + (exhaustive draw rate) = 100%</code> of games. The average win rate is 19.125%, so the exhaustive draw rate is 23.5%.</ref>
