* | * When at least one of the hand's current winning tiles have been discarded before, the hand enters furiten. A tile does not have to be in your discard pile to invoke furiten; if an opponent [[naki|called]] your discarded tile, it will still trigger fuirten. | ||
* | * After declaring [[riichi]], if the first winning tile is skipped, the hand permanently enters furiten. | ||
* | * When not in riichi, when a winning tile is skipped, the hand enters temporary furiten. This furiten lasts until the player's next draw. | ||

While in furiten, the hand is unable to call ron upon a discard. However, it can still win via self-draw, assuming the hand has valid yaku. | |||
Note: If a hand is in furiten, it is unable to win off ''any'' player's discard, regardless of which tile caused the furiten. For example, if your hand is waiting to win with 2p and 5p, and you had discarded 2p before, you are unable to win off an opponent's 5p. | Note: If a hand is in furiten, it is unable to win off ''any'' player's discard, regardless of which tile caused the furiten.

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. | It is important to bear furiten in mind when developing a hand.

A common reason for furiten is when a player is in tenpai with an open hand, but it has no guaranteed yaku. In these cases, the hand will only gain 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: | A common reason for furiten is known as "[[atozuke]]": when a player is in tenpai with an open hand, but it has no guaranteed yaku.

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]]. | ||
