One so-called "system" after another purports to tell players how to clean up in Bingo for cash games time after time, just by knowing which cards to reject and which to buy. One game after another demonstrates that these systems seem sound in theory but almost always crumble in practice with a narrow few exceptions.
In fact, there's only one even somewhat-solid modus operandi for picking Bingo for cash cards. Even that proven edge is a very slim one, and rarely enough to really "take" the house in one of the purest games of chance.
● Granville & Tippett
Two otherwise remarkable statisticians and analysts can lay claim to the most widely - and mistakenly - accepted theories of finding order in a Bingo for cash draw's chaos. …show more content…
Granville theorizes in How To Win At Bingo (currently out of print, but with reviews littered here and there online) that an equal distribution of odd and even numbers of both low and high totals afford the greatest chances to win. On the other hand, "extreme" distributions that lean toward low, high, even or odd integers puts too many eggs in one "basket" to keep probabilities of drawing your numbers high.
L.H.C. Tippett is a more curious case. Respected despite being so obscure that many sources referencing him misspell his name, he believes the secret to a Bingo for cash winning streak is more akin to the secret to raising a big family: it's all in the balls. His theory holds that the closer the average of a card's numbers is to 38 in a 75-ball Bingo game or 45 in a 90-ball game, the greater the chances of winning in a drawn-out game with a great many numbers being called. Of course, he also posits that totals far off that average tend to perform better in expected shorter games.
