(remove the sanmenchan wait patterns, since they aren't *really* relevant for suji. also remove the JP names (more confusing than anything)) |

Suji relies on the "mahjong intervals" of 1-4-7, 2-5-8, and 3-6-9, as shown in the picture to the right. When using suji, two numbers in an interval will be paired, such as 1-4 or 2-5. | Suji relies on the "mahjong intervals" of 1-4-7, 2-5-8, and 3-6-9, as shown in the picture to the right.

In short: a tile becomes safer against an opponent if they've discarded every possible tile (of the same suit) that is in an interval of 3 from that tile. For example, if an opponent had discarded a 4, then both 1 and 7 of the same suit are safer. If an opponent discarded both 1 and 7, then the 4 becomes safer. (If an opponent had only discarded a 1, the 4 is not much safer.) | In short: a tile becomes safer against an opponent ''if'' they've discarded every possible tile (of the same suit) that is in an interval of 3 from that tile.
