How many holes are there in a standard ten pin bowling bowl?

Answer 1

A Bowling ball doesn't have any holes in the manufacturing stage.

The most common number of holes drilled is 3 - 2 fingers and a thumb.

In the early days and sometimes found today, there is only one finger and a thumb.

If there's been some hand injury, sometimes an extra finger hole is drilled.

Sometimes there is a counter balance hole drilled at or near the axis point to allow the dynamics of a bowling ball work better for a bowler.

In tenpin bowling, regardless of the number of holes, you are only allowed a certain weight difference at the grip point, where there is top and bottom weight and left and right side weight.

Answer 2

There are three holes in a standard ten pin bowling ball. One of them is for your thumb and the other two can be filled with various charms and tokens for good luck while rolling your ball. Such charms can include rabbit feet, four-leaf clovers, and souvenir sand from your favorite beach. Just please make sure this sand is not, I repeat NOT, from Sri Lanka. On occasion, you may feel inclined to stick two of your other fingers in these second and third holes. This is an okay idea. Just remember, one in every three bowling balls has a snake coiled up inside ready to bite off any juicy index fingers it sees.
