If the players reach a stalemate situation, as determined by either their own indication or the referee's judgment, they may choose to discard the scores from the current frame and restart it.

Other plastics and resins such as polyester (similar to those used for bowling balls) and clear acrylic are also used.The main purpose of the rack line and it's markings is to best ensure that all rack setups are equally and consistently for both players or teams, regardless of who is setting them up.

If the cue ball is just a tad bit bigger, the table redirects it to an exit instead of holding onto it like it does the object balls. If any reds remain unpotted at the end of a break, the remaining red balls are "on" for the opponent's first shot.

Example: Striker pots a red, cue ball comes to rest touching the green, and the striker declares that ball as on. Points are scored for potting balls legally, in accordance with the rules described below, or in the event of a foul committed by the opponent. If they are not, and the break goes ahead, then everyone involved with the frame has accepted the rack for what it was, and the frame simply continues as normal without any further actions.

A common defensive tactic is to play a shot that leaves the opponent unable to hit a ball "on" directly.There has often been some confusion regarding which end of the table is the 'top' and which end is the 'bottom'. Sometimes in sports commentary on the TV, the ends may be swapped over, because that's how they appear on the television from the usual camera angle facing up the screen towards baulk. In the realm of carom billiards games, three balls are used to play most games on pocketless billiards tables.
