While in furiten, the hand is unable to call ron upon a discard. However, it is still winnable via self-draw, assuming the hand has valid yaku. Note: when any winning tile triggers furiten, the ''entire'' hand is furiten. | While in furiten, the hand is unable to call ron upon a discard.

All of a player's discards can be checked at any time during play, by looking at their discard pools and the rotated tiles in other players' tile calls. This leads to the most basic strategy to avoid dealing into a player's hand: tiles they have already discarded are guaranteed safe against a ron call from that player. | All of a player's discards can be checked at any time during play, by looking at their discard pools and the rotated tiles in other players' tile calls.

During hand development, it is important to bear furiten in mind. Most of the time, if a hand gets to tenpai and is furiten at that point, it indicates that the hand was inefficiently developed. This is not always the case, as sometimes a player makes a tactically correct decision and finds themselves in furiten anyway. | During hand development, it is important to bear furiten in mind.

The most common reason for furiten, however, is when a player is already tenpai with an open hand, and does not have a guaranteed yaku. While they may have a winning tile that provides them with a yaku, if they draw another tile which completes the hand without a yaku, then they will be forced into furiten on the next discard.

*A [[shanpon]] wait, with one tile completing a [[yakuhai]] triplet, and the other having no yaku. | |||
*A [[ryanmen]] wait on 14 or 69 on a hand that would otherwise complete [[tanyao]]. | |||
These type of cases are known as [[atozuke]]. | |||
Finally, a player considering a [[daburu riichi|double riichi]] should carefully inspect their hand before discarding; if they had a complete hand to begin with, then being in furiten will add insult to the injury of having [[http://osamuko.com/delicious-riichi-button-must-click-it/ passed]] on a [[tenhou and chiihou|tenhou or chiihou tsumo]]. | Finally, a player considering a [[daburu riichi|double riichi]] should carefully inspect their hand before discarding; if they had a complete hand to begin with, then being in furiten will add insult to the injury of having [[http://osamuko.com/delicious-riichi-button-must-click-it/ passed]] on a [[tenhou and chiihou|tenhou or chiihou tsumo]]. | ||
