Granville System
The Granville System is a strategy often used in bingo, developed by Joseph E. Granville, a financial writer known for his work on stock market prediction theories. He proposed applying similar principles to bingo and developed a system based on probability theory.
The Granville System is reliant on three main principles:
The Balance Rule: This rule is based on the assumption that, in bingo, there will be an equal number of numbers ending in 0-9 drawn throughout the course of the game. Therefore, he advises picking bingo cards that have as much number variety as possible.
The Parity Rule: This rule suggests that at any point during the game, the chances of even and odd numbers being drawn are roughly equal. This means you should have approximately an equal amount of even and odd numbers on your bingo cards.
The High and Low Numbers Rule: This rule is based on the idea that, in a game of bingo, the likelihood of high and low numbers being drawn is roughly equal. Therefore, your bingo cards should have approximately an equal number of high and low numbers.
It's important to note that while the Granville System may increase your chances of success in bingo, it doesn't guarantee a win as bingo is a game of chance.
