# Systematic Bingo Profits

Bingo can be a myriad of betting numbers, game cards and luck, but if you adopt a systematic approach to the game you can give yourself a better than average chance of winning. While it’s never possible to say that you can guarantee a profit when you play, it is possible to use mathematics to uncover an interesting pattern present in every game of bingo.

Joseph E. Granville was the first person to spot a potential aspect of the game which a player could use to their advantage when choosing their game card. The crux of Granville’s theory centres on the population average of a game and the number of balls in play.

After using his mathematical savvy to assess the game of bingo, Granville discovered that the population (in this case the numbers shown on a game’s master board) usually has an average similar to half the number of balls in play. This assumption is based on L.H.C. Tippet‘s statement that, “As a random sample is increased in size, it gives a result that comes closer and closer to the population value.”

In the case of bingo, this means that the average of the population will move closer to a figure that represents half the total number of balls in play. Thus, if there are 70 balls in a game then the population average will gradually converge on 35. Similarly, if there are 90 balls in play then the average of the population will slowly move towards 45.

This information is significant because it suggests that if you can choose a game card where the average is close to 35 (70 ball game) or 45 (90 ball game), then you have more chance of winning free bingo without deposit. While many will assume that the balls appear at random, there is a discernible pattern that you can use to your advantage. Although this method won’t guarantee you a profit, it will give you a more systematic way of choosing your game cards. Moreover, this will give you a better than average chance of making money when you sit down to play bingo.
