There has been quite a bit of discussion online about whether or not Bingo balls can be rigged. The short answer is that it is theoretically possible, but it is very difficult and would require a lot of effort.
In order to rig a Bingo ball, someone would need to get access to the ball before it is printed out and then alter it in some way. This could be done by adding extra numbers or by changing the shape of the ball.
It would also be necessary to get the ball into the hands of the person who is going to use it in a game, which is not easy to do.
There have been no reports of Bingo balls being rigged, and it is extremely unlikely that this would ever happen. However, it is possible, so anyone who is concerned should take precautions such as not leaving their ball unattended or making sure that it is always checked for tampering.
