In riichi mahjong, your final placement (1st/2nd/etc.) is often important. Due to the [[oka and uma]] systems, you can gain huge bonuses or penalties when changing place. In competitive environments, your placement can be important for gaining rating points. Therefore, players should act differently as the overall conditions change. For example, when given the exact same hand, a player with a huge lead might not want to [[riichi]], but a player far behind may be desperate to riichi. Therefore, it is not only important to look at your own hand, but both your and your opponents' current points as well.

In the online clients [[tenhou.net]] and [[Majsoul]], there is a huge penalty for 4th place ''for players at a high rank''.

It is important to restate that an extreme level of 4th place avoidance only applies when you are at a high rank. At lower levels, it is best to improve on ''average placement'' (including fundamentals like [[tile efficiency]] and [[defense]]) rather than focus on avoiding 4th specifically. At these high ranks, do what you can to avoid being last - try not to take risks late in the game, even if there is no immediate threat of being 4th.

These online clients have big penalties to encourage players in 4th to not leave the game. In most real life areas of play, the point distribution is more even (they tend to favor 1st place, due to the [[oka]] system). Of course, no matter where you play: if you are currently in 4th place, you should obviously do what you can to escape.

Also, note that once you reach Celestial in Majsoul, there is no more special 4th place penalty. At Celestial, the point rating becomes 0.5/0.2/-0.2/-0.5, so there is no special need to avoid fourth.
