The rules for a “boo” sound to be played works like this. When the game plays either the organ or chant sounds, it takes precedent over the boo button. These sounds are played every 20 seconds, and each last between 6-10 seconds. This fills the game up with action but limits the opportunities to play the “boo” sounds.
The “boo” sound block is two sound blocks (Boo’s and Cheer’s). They are alternated throughout the game (boo then cheer) as each press is played, and to enhance the gameplay there are different sayings being played. The table of sounds is below.

The puck solenoid does not fire at every press but rather after ~3 seconds from the last press there is a new press then the solenoid will fire (you can press in between the solenoid firing). This was to eject a puck if the eject sensor failed or it fired when the puck wasn’t loaded to be fired.
