Classic format for training, club tournaments, and warm-up before three-cushion.
Point counts when cue ball in one stroke contacts both other balls. Order of contacts does not matter.

Straight rail — basic discipline: one point when cue ball contacts two object balls without mandatory cushion rebounds.

Used for training and club tournaments in France and Belgium; survives as amateur and practice format.
Three-cushion grew from straight rail by adding the cushion requirement.
| Straight rail | Three-cushion | |
|---|---|---|
| Cushions | Not required for score | Minimum 3 rebounds |
