A simple dot in
snooker
can be the difference between a victory and a defeat. Sometimes a colour (has to be the black pink or blue) is potted. Because there is no dot i do not know exactly where the ball is to be placed after potted. Sometimes the ball is put right in front of the cueball. This is because i thought the ball was going to be put a few centimetres to the left or right but wasn't. If there were dots to indicate where the ball is placed i would not have been snookered.
