*"Full" suji 4, 5, and 6 are about as safe as suji 2 and 8. "Half" suji 4, 5, and 6 are not safe. | |||
**Note: Full suji is when both suji interval tiles are safe. Half suji is when only one suji interval tile is safe. So a 1 being safe makes 4 half suji; both 1 and 7 being safe makes 4 full suji. | |||
Using suji on the riichi declaration tile is more dangerous than normal. This is because of the ryankan shape (e.g. 135, 246, or 357). Ryankans are often kept as they can improve [[tile efficiency]]. But if the hand reaches tenpai with a ryankan intact, then it must discard one of the tiles. In this case, a player can discard the 5 and wait on the suji tile 2. | Using suji on the riichi declaration tile is more dangerous than normal.
