*[[Shuntsu|Sequences]] are comprised of three sequential tiles. Therefore, an open wait will win off two tiles that are 3-apart. For example, {23} can win off either a 1 or 4 of the same suit. {34} can win off 2 or 5 of the same suit. This continues until you get the intervals of: 1-4, 4-7, 2-5, 2-8, 3-6, and 3-9. | *[[Shuntsu|Sequences]] are comprised of three sequential tiles.

*Due to the [[furiten]] rule, if a player has previously discarded any tile they could have won off of, they cannot win from other players. | *Due to the [[furiten]] rule, if a player has previously discarded any tile they could have won off of, they cannot win from other players. | ||
*Therefore, if a tile in a suji interval is safe, then other tiles in that interval | *Therefore, if a tile in a suji interval is safe, then other tiles in that interval become safer against that player. For example, if an opponent discards a 4, then the 1 of the same suit is safer. This is because, if they had a wait that wins off the 1-4 interval (such as {23}), then it would be subject to furiten. Similarly, the 7 also becomes safer when a 4 is discarded, due to the 4-7 interval. | ||
Note: suji also applies to the other forms of furiten. After an opponent declares [[riichi]], then any non-winning tile discarded by anyone becomes safe. Therefore, suji can be applied to these tiles as well. If an opponent declares riichi, and the next opponent discards a 4, then 1 and 7 are also considered suji. | Note: suji also applies to the other forms of furiten.
