Compared to other "general" variants of mahjong, such as Hong Kong or Singaporean:
*Yaku are less important for the value of the hand. You need at least one yaku to win, but in general, yaku are less important to focus on. This is because of [[riichi]] and [[dora]]. By using riichi and/or dora, hands can be valuable without sacrificing much speed. Therefore, slower/more difficult yaku have a harder time competing.

:The "[[mangan]] limit" also contributes to this point. Each han roughly doubles the score until ~4 han (specifically, at 8000 points), where you reach mangan. Past this point, each han become less effective at increasing your score. Therefore, 4 han hands are great for efficiency.

*Defense is a major part of gameplay, due to riichi and furiten. Furiten allows players to defend reliably. Riichi gives players a reason to defend - they do not want to deal in. Tsumo is not worth ''as'' much as in other variants.

*Placement is important in most places where riichi mahjong is played. The oka and/or uma encourage players to rise in ''place'' rather than rise in points. Going from 2nd to 1st in the last round might be worth the equivalent of a [[yakuman]], depending on the settings. In online clients, placement is often the main factor for determining rating.

*[[Defense]] - which tiles are safer than others. Also, learn to defend and not just push every hand you get.

*Common values for [[scoring]] and the other yaku. Note that some yaku, like [[honroutou]] and [[sankantsu]], are slow, rare, difficult, and not worth very much. Others are more useful.
