When a player has a "233", it is unlikely for them to discard a 3 early - turning "233" -> "23" - since it'd come at a loss of [[tile efficiency]]. So if a 3 is discarded early, it is less likely for them to have "23" (which waits on 1-4) or "34" (which waits on 2-5) remaining. Therefore, an early discarded 3 makes both 1-4 and 2-5 into matagi suji. | When a player has a "233", it is unlikely for them to discard a 3 early - turning "233" -> "23" - since it'd come at a loss of [[tile efficiency]].

The tiles towards the outside (1 & 2 in this example) are known as [[sotogawa]] and are significantly more safe than normal. Tiles towards the inside (4 & 5) are not much safer; the 4 actually becomes more dangerous than normal due to [[ura suji]].
