If you get more than 2 winning patterns, it will continue to red spin until all patterns/payouts have been awarded. For example, if you get a red spin after getting mixed bars, the red spin will be something equal to or greater than the mixed bar payout. The spins are awarded from lowest to highest. Red spins occur when you have more than one winning bingo pattern on your card. They don't realize it's just 'advertising' so to speak. I've seen people under the assumption that they have to 'wait' or 'pick' a pattern to go for lol. You can watch the screen before playing it will cycle through all the winning bingo patterns and what they pay on each bet.
I still get pleasantly surprised, but it doesn't happen often anymore.
To be honest, it does take a little of the fun away knowing how the bingo numbers and patterns work, and once you learn a certain game's patterns and payouts, you often have a good idea what's gonna come up when the machine red spins.
I've been playing these pretty heavily since early summer, and I think I've finally got them figured out. My favorites are the Lucky Ducky, Crazy Bill's and the other 3 reel slots with the red spin features. Being in west Arkansas, the closest casinos we have are eastern Oklahoma Indian casinos, which are known for the Class II bingo slot machines.
