Extra Balls
Almost all the bingo's are five ball games, and you have the option to try and get up to three extra balls by playing credits or depositing coins after the fifth ball is shot.
The likelyhood of getting extra balls decreases as the payout odds/feature levels increase, and getting successive extra balls is less likely than getting the first one.
In some games, it's actually impossible to get an extra ball 50% of the time if certain features are lit!
