It is important to bear furiten in mind when developing a hand. Frequently, if a hand gets to tenpai and is furiten, then the hand was inefficiently developed. This is not always the case, however, as a player can make a correct decision but still be in furiten.

A common reason for furiten is when a player is in tenpai with an open hand, but it has no guaranteed yaku. In these scenarios, a hand only gains yaku if it draws a certain winning tile. If a different winning tile is drawn, the hand will have no yaku, and is thus forced to discard its own winning tile - entering furiten. This most commonly occurs with:

The primary purpose of the rule is to prevent a player from targeting a later player in the turn order. Once a player sees a tile discarded, they know that they can follow with the same tile and it will be safe for that turn.

A player may deliberately skip a win, entering temporary furiten in the process. This is often done after [[situational analysis|point standing analysis]]: for example, if a player is close to [[tobi|bankrupting]], a player in 1st may want to target them in order to end the game faster. When close to [[orasu|all last]], a player may need to ron a specific player to [[gyakuten|rise up in rank]]. Temporary furiten can also be entered by a player who does not have a guaranteed yaku, as described above. Otherwise, a player may mistakenly enter furiten if they don't know their waits correctly.

Rarely, some rulesets [[Rule variations#Furiten|vary the rules]] by allowing a tile call made by another player to cancel temporary furiten.
