Theory of chances in Keno
In Keno each round (called a race) has nothing to do with the previous one as the balls fall in a random order and have no clear sequence. In theory, every ball can be drawn an unlimited number of times in unlimited number of rounds. But even in this scenario, some players notice some patterns. If you believe in this theory, you need to choose the numbers that weren’t drawn during several previous rounds. There is a strong probability that they will be selected. However, you never know.
Instead of betting on numbers that were selected long ago, other players choose to bet on numbers selected more often. Other players claim that the “lucky numbers” are the consecutive numbers i.e. if the number 50 was selected, then the lucky number should be 51 etc.
There is a very interesting technique called “bet on the outcome of reciprocal event”. This theory is based on the assumption that “You can’t step into the same river twice” i.e. identical events cannot occur several times in a row. The followers of this strategy are of the opinion that in order to win, you need to analyze the statistics of all previous rounds. Based on this analysis players should bet on those numbers that haven’t been selected yet.
