Quoted from CarShark:
Are those machines from the same Belgian company that Nick Baldridge mentioned or C2C?
Nope! Good question, though. These are not real bingos. These are oddball 1/2 to 1/4 size bingo-esque games. The post placement and ball size is odd. Are those ping pong balls? A Bally or United bingo is truly a game of skill when you don't consider the multi-coin aspect (which I'm not trying to white-wash over, believe me - gambling is gambling). These, I'm not so sure the gameplay holds up... that said, I don't understand what the buttons do. Nor do they have real advancing odds? Again, not sure what the backglass is telling us.
Perhaps someone can explain the gameplay?
As to the Belgian bingos, those games (not these) are almost 100% carbon copies of Bally's playfield design. 25 holes and a ball return. The backglass or gameplay is either a 6 card-style, a miss America style, or some interesting looking LCD choose-your-own bingo affair.
Would be interested to know more about these pictured games, but they don't appear to hold a candle to bingo pinball.
