Rotation, sometimes called rotation pool, 15-ball rotation, or 61, is a pool game, played with a pocketed billiards table, cue ball, and triangular rack of fifteen billiard balls, in which the lowest-numbered object ball on the table must be always struck by the cue ball first, to attempt to pocket numbered balls for points.[1]
Each player's points are increased by the corresponding number of the ball pocketed. So, if a player pockets balls numbered one through ten, their score will be fifty-five. Some spectator attractions of rotation include performing unconventional or difficult shots to reach the correct ball, and quite often making risky attempts to score a higher amount of points. This can be achieved by performing advanced shots such as combination shots, bank shots, and swerves. These in addition to the fortitude to mentally, with knowledge, act out each planned play; complex problem solving displayed when physically performing each cue ball play are the players' main attractions.
