However, if said snooker is achieved by having the free ball obstructing the ball on, then the strike is a foul and a penalty of the value of the ball on is awarded to the opponent. The following fouls award seven points to the opponent when committed:[1]. Snooker is a cue sport that is played on a baize-covered table with pockets in each of the four corners and in the middle of each of the long side cushions. In both cases, the free ball will be re-spotted and the actual ball(s) on will remain off the table. This order is often remembered using the mnemonic God Bless You, the first letter of each word being the first letter of the three colours (Green, Brown, Yellow).

A common strategy for this shot involves placing the cue ball on the baulk line, between the brown ball and either the green or yellow ball. The colour will then be respotted, the player will nominate a colour to be on for the next shot, and normal play will resume. . The player must still put sufficient strength into the shot so that the cue ball would be able to reach its target if it were not obstructed, and attempt a shot that could succeed if the obstruction were not present. Depending on the situation, these balls will either remain off the table; be returned to their original spots; or be replaced in the positions they occupied before the foul shot, along with any other balls that were moved during the shot. The player could then pot the chosen colour as if it were a red for one point. To achieve it, the player must pot all 15 reds, with the black after every red, followed by potting all six colours. Touching any ball before all balls have come to a complete stop. It is sometimes erroneously believed that potting two or more balls in one shot is an automatic foul. A match ends when one player has won enough frames to make it impossible for the other player to catch up. After all six colours have been potted, the player with the higher score wins the frame (but see below for end-of-frame scenarios). As missing due to avoiding a direct shot on a ball is usually a tactical, rather than skill-related, outcome, this rule is rarely invoked, as a player will simply hit the ball directly on the third shot. If a free ball has been granted (see below), a colour may be legally potted in the same shot as a red or another colour, depending on the circumstances. The penalty for a foul is thus no lower than four points and no higher than seven. Players and former players, professional and amateur referees from all over the world as well as referee examiners and tutors have worked relentlessly over the past two years to produce a revised Rulebook for the games of Snooker and English Billiards and we are confident that we have created a Rulebook to suit the need of our ever developing worldwide sport.”. Similarly, in order to cut out carelessness, if balls move because a player dropped an implement on the table, or brushed a ball with their clothes, the offending player will have to replace the balls to the satisfaction of the referee and their  opponent.
