Cadre

Score points for legal ball contacts inside a rectangular zone (cadre) marked on cloth or implied by spot marks.

Discipline demands precision: balls must stay in zone or enter per specific variant rules.

• Variants: cadre 47/2, 52/2 and others — zone size and scoring set by regulations.
• Popular in European federations as complement to three-cushion.

• Rectangle (cadre) marked on table — lines from spot marks on cushions.
• Scoring contacts — when both balls (or cue ball and object ball) are in zone at moment of score.
• Ball leaving cadre line without permitted contact — no point or penalty.
• Starting "box" — stroke only from D or baulk line if cue ball is in zone.

• Red and cue ball placed inside cadre or at starting points per regulations.
• Lot determines first player and white ball assignment.
• After foul — opponent's ball-in-hand per discipline rules (often from D).

Point — for stroke meeting cadre conditions: contact with two balls (as in straight rail) or with rebounds — per variant regulations.

Main difference — geographic limit: play in a narrow zone, not the full table.

• Tactics: keep balls in cadre and deny opponent easy ball-in-hand.
• Long rebounds are risky — may send ball over the line.

• Short strokes and precise cut matter more than power.
• Break possible while player does not miss or cross cadre boundary.
• Change of innings — as in other carom disciplines.

• Ball stayed or left cadre without score — no point; penalty per regulations.
• Stroke outside permitted ball-in-hand zone — foul.
• General carom fouls: double hit, push shot, touching by hand.
• Dispute on ball on line decided by referee (ball on line often counts "in zone").

• 47/2 and 52/2 — cadre size in centimeters; confirm with organizer.
• Club play may simplify zone for training.
