The highest possible snooker break, also known as a "maximum break," consists of potting all 15 red balls with 15 black balls, followed by the yellow, green, brown, blue, pink, and black balls in sequence. This results in a total score of 147 points, which is the maximum number of points that can be achieved in a single frame of snooker.

A maximum break is a rare and highly prestigious achievement in professional snooker, and it requires not only exceptional potting skills but also precise positional play and control of the cue ball.
