So weird... that's what they told me at the lanes when I went bowling in Amsterdam and the ball only had two finger holes. That was some rough bowling.

From this site:
http://www.topendsports.com/sport/tenpin/drilling.htm#holes
"The rules of tenpin bowling allow for a total of 12 holes in each ball.
You are allowed one for each finger and thumb for gripping purposes.
You are all allowed one small vent hole for each of the fingers and thumb holes, to prevent popping at the release point.
One hole for balance purposes, not to exceed 1 1/4" in diameter, to bring a ball into static weight tolerances.
The last is a "mill" hole for inspection purposes, not to exceed 5/8" in diameter and 1/8" in depth. This is used to check the hardness of the cover stock just below the actual surface of the ball. This is the hole seen on equipment used by members of the PWPA and PBA National Tours just above the finger holes."
So, just to emphasize the point, you're legally allowed five fingerholes (not a maximum of 4). Found that out in about 10 seconds of research. Real good job, Factropolis. Another gutter ball!
