An apparent good pocket hit that only knocks down 8 pins; typically the right handed players will leave the 4-7 spare and the left handed players the 6-10; usually the ball is a tad high when this happens.
A game played with wooden balls shaped like wheels of cheese. The balls are rolled down a dirt or synthetic alley towards a feather sticking out of the dirt at the other end. The object of the game is to get the ball as close to the feather as possible. Teams take turns rolling 12 balls and may knock their opponent's balls out of the way, similar to Bocce. The team with balls closest to the feather at the end of the game wins. The game has its origins in Belgium. The only place to play the game in the United States is the Cadieux Cafe in Detroit, Michigan; an imitation version, called "Belgian trough bowling" is also available at the Bath City Bistro in Mount Clemens, Michigan.
A grip in which the bowler inserts fingers to the first joint, with the combined total of angle of the two joint equals 90 , while placing the entire thumb in the ball.
Imbalance which effectively makes the side of the ball, divided by the midline, containing the finger holes heavier than the side containing the thumb.
A bowling variant which is popular in Canada, where many bowling alleys offer it, either alone or in combination with ten-pin bowling. It was devised in the early twentieth century to offer bowlers the chance to play a game during a half-hour lunch break. This goal was achieved by using smaller balls which travel faster than ten-pin balls and which can be thrown in rapid succession.
1) The bowling ball changing its axis of rotation during its path down the lane. The result is several different oil rings being visible around the ball.
2) The action of your arm or elbow when it goes away from your body in the armswing or during the release; generally not desirable.
A lane oiling pattern that places the same amount of oil across the entire width of the lane. Usually a very challenging condition as there is no block or crown; can be very low scoring if it deteriorates into a reverse block.
The normal gutter is shaped somewhat oval so that the ball can roll purely and cleanly to the pit area if it goes into the gutter early...the channel effect; however, at the end of the lanes by the pins, the gutters are flat, not ovaled. The height (from the pin deck to the bottom of the flat gutters) is regulated by the USBC as if the flat gutters are too high, they will allow much better pinfall as pins will deflect off the sideboards and bounce back onto the lane much easier resulting in more pin action.
The industry standard for measuring the maintenance performed on pinsetter machines. Most centers will track the number of frames before the machine needs human intervention to continue running, not including preventative maintenance. An adequate amount is 1,500 frames per stop. Machines that are extremely well taken care of will average upwards of 2,000 frames per stop.
