As we have said, bingo is the game of the pure luck, and all we can do is choose our lucky numbers and wait for the best outcome. But British statistician, Leonard Tippet did not think so. Namely, his Tippet theory is that if you play bingo that contains numbers from 1 to 90 in the quick draw, you should dial numbers 1 and 90. While if you play bingo whose draw lasts longer than 5 minutes, you choose numbers that are close to the middle number (in this case 45 because bingo is up to 1 to 90).
