A 0%-house-edge bet added to Pass Line or Don't Pass once the point is set.
It pays true odds: on the Pass Line side, 2 to 1 on a point of 4 or 10, 3 to 2 on 5 or 9, 6 to 5 on 6 or 8; the Don't Pass side is the reverse. Each table sets a cap, most often 3-4-5X. A Pass Line bet with full odds has a combined house edge of 0.374%.
