Maximum break - snooker

The maximum break in snooker under normal circumstances is 147. This is often known as a maximum, a 147, or orally a one-four-seven. The 147 is amassed by potting all 15 reds with 15 blacks for 120 points, then all six colours for a further 27 points. The maximum break has been achieved 77 times in professional competition. Ronnie O'Sullivan and Stephen Hendry have both compiled 10 official maximum breaks, the most ever by any professional player. Scores above 147 are possible in the case of free ball due to fouling by the opponent.
