Except when clearly contradicted by these additional rules, the General Rules of Pocket Billiards apply.
Type of Game
Something that maybe ought to be British. To make a count the shooter
must, on one or two strokes, sink two balls whose numbers add to fifteen.
Individuals, or teams.
Object balls numbered 1-15, plus the cue ball.
Standard triangle rack with the apex on the foot spot and the 15-ball in
the center of the triangle (as the 8 is in 8-ball). Other balls are
Object of the Game
To have the most cribbages (pairs of balls which add to 15 or the 15
itself) when the table has been cleared.
A cribbage is legally scored when a pair of balls are sunk which add to
15. Usually this is done in two strokes with each ball of the pair
being made on each stroke (a ball must be made to continue shooting).
Both balls making a cribbage are allowed to be sunk on a single stroke
The opening break must drive at least four object balls to a cushion
(doesn't have to be the same cushion!). If this doesn't happen opponent
has option of re-break or taking balls as they sit.
Rules of Play
The 15-ball can't count as a cribbage, or legal shot, until all pairs
adding to 15 have been taken from the table.
Player's first stroke on a cribbage try can use combinations to sink the
called object ball. If the called object ball is sunk and nothing else
falls player must, on his next stroke, sink the second ball of the
cribbage cleanly (that ball can't touch another object ball) in a called
pocket. If the second object ball is missed the first object ball of
the cribbage try will be spotted and the shooter's turn finished. If
more than one object ball is sunk when calling the first ball of a
cribbage all balls will be spotted and the shooter's turn ended unless
the only other ball sunk was the second ball of the cribbage pair.
(A twist on the game is to play to a set number of cribbages, say 15 or
20, and use the 15-ball as the break ball in 14.1 Continuous.)
Illegally Pocketed Ball
Any illegally pocketed balls will be spotted, in numerical order with
lowest numbered ball closest to the foot spot.
Jumped Object Ball
Any object balls which leave the playing surface (and don't return to
it) will be spotted, in numerical order with the lowest ball closest to
the foot spot.
Cue Ball After Jump or Scratch
Will be put into play from behind the head string. (Shooter must play
out of the kitchen.)
Penalty for Fouls
Offending player must spot one of his cribbages or (if he has no pair to
spot) owe the table a cribbage. The cribbage will be spotted with
lowest ball closest to the foot spot.
Cue ball will stay as is or be put in play from the kitchen depending on nature of foul. "Touch" fouls will have cue ball played from where it sits. A scratch or jumped cue ball will be played out of the kitchen.
