A riichi declarer is furiten when he has missed a chance to call ron against a winning tile after his riichi declaration. The ignored winning tile may have been a discarded tile or a [[Chankan|tile used to extend a minkou to a shominkan]].  The player will remain furiten for the rest of the hand and thus cannot call ron on any tile. Furiten applies even, if it is a different tile than the ignored one. This rule requires knowledge of all own [[machi|possible waits]].
After declaring riichi, the discarded tile immediately after the declaration is turned sideways.  The purpose is to indicate, when the player had declared riichi.  By rule of riichi, a player is simply waiting for winning tiles after that point.  Any tiles discarded after the riichi declaration are deemed as [[safe tiles]].
 
So, a riichi declarer is furiten when a chance to call ron has been declined. The ignored winning tile may have been a discarded tile or a [[Chankan|tile used to extend a minkou to a shominkan]].  The player will remain furiten for the rest of the hand and thus cannot call ron on any tile. Furiten applies even, if it is a different tile than the ignored one. This rule requires knowledge of all own [[machi|possible waits]].
 
In a sense, this disallows a riichi declarer to be deceptive with regards to winning tiles.  The player may decline ron from one player and expect to declare against another player, off of the same time.  Naturally, during furiten, a declared riichi disallows that style of player.  However, this tactic is acceptable via [[damaten]] or with an open tenpai hand.
