The colours must next be potted in the ascending order of their values, from lowest to highest, i.e. yellow first (worth two points), then green (three points), brown (four points), blue (five points), pink (six points), and finally black (seven points); each colour remains in the pocket after being potted. The typical combination lock design involves a set of (usually three or four) disk tumblers around a spindle connected to the external dial. To determine which pin stacks have these pins, gently push up each "set" pin. If, after a foul, the next player cannot cleanly strike both sides of the object ball, the referee may call a free ball, allowing the player to nominate any other ball in place of the object ball they might normally have played. If a player is awarded a free ball with all 15 red balls still in play, they can potentially make a break exceeding 147, with the highest possible being a 155 break, achieved by nominating the free ball as an extra red, then potting the black as the additional colour after potting the free-ball red, followed by the 15 reds with blacks, and finally the colours.

Association croquet is played between two individuals or teams, what is billiards each playing with two balls. The image's caption describes the game as "a curious ancient pastime", confirming that croquet games were not new in early-19th-century England. Golf croquet is played between two individuals or teams, each playing with two balls. In the initial rack in straight pool, fifteen balls are racked in a triangular rack, with the center of the apex ball placed over the foot spot. If there are not enough points remaining on the table for a player to win the frame, that player may offer to concede the frame while at the table (but not while their opponent is still at the table); a frame concession is a common occurrence in professional snooker. Snooker has faced criticism for matches taking too long. The World Championship uses a longer format, with matches ranging from the best of 19 frames in the first round to best of 35 for the final, which is played over four sessions of play held over two days. Some early world finals had much longer matches, such as the 1947 World Snooker Championship, which was played over the best of 145 frames.

The UK Championship, held annually since 1977, is considered to be the second most important ranking tournament, after the World Championship. Although some success was achieved with this format, it did not receive the same amount of press attention or status as the regular ranking tournaments. Mathematical billiards is an idealisation of what we experience on a regular pool table. The total number of consecutive points (excluding fouls) that a player amasses during one visit to the table is known as a "break". A snooker match generally consists of a predetermined number of frames. The number of balls used in pool range from one to fifteen depending on the game type. If dissatisfied with the position left after a foul, the next player may nominate the opponent who committed the foul to play again from where the balls have come to rest. All competitions are open to professional players who have qualified for the tour, and selected amateur players, but most events include a separate qualification stage. If both players agree, the balls are returned to their starting positions and the frame is restarted (known as a "re-rack"), with the same player taking the break-off shot as before.

If the scores are equal when all of the object balls have been potted, the black is used as a tiebreaker. Some additional secondary tours have been contested over the years. Breaks of 100 points or more are referred to as a century break, and are recorded over the career of a professional player. 195 officially confirmed maximum breaks achieved in professional competition. A maximum break in snooker is achieved by potting all reds with blacks, then potting all six colours, yielding 147 points; this is often known as a "147" or a "maximum". At the start of each player's turn, the objective is to first pot a red ball, unless all reds are off the table, or the player has been awarded a free ball, which allows them to nominate another object ball instead of a red. The responsibilities of the referee include announcing the points scored during a break, determining when a foul has been committed and awarding penalty points and free balls accordingly, replacing colours onto their designated spots after they are potted, restoring the balls to their previous positions after the "miss" rule has been invoked (see Scoring), and cleaning the cue ball or any object ball upon request by the striker.
