The Number 21 is one of the red roulette wheel numbers
The number 21 is a pretty special number in blackjack. But what about on the wheel? Does it hold any special significance as a number on a roulette wheel?
Twenty-One is one of the red roulette wheel numbers that sits between black 4 and black 2 on a European wheel (single-zero) and between black 6 and the number 33 on a double zero roulette wheel (American).
21 is a Fibonacci number, which will be of interest to you if you play the Fibonacci System. Interestingly, the numbers it contains are both Fibonacci numbers (1,2) and the sum of those (3) is a Fibonacci number. You could say that 21 is a Fibonacci Max number!
21 is also a triangular number (the number of objects that can be used to form an equilateral triangle -think of a rack of balls on a snooker table) and an octagonal number. Other triangular numbers include 2, 6, 10 and 15.
If you add up the first 6 natural numbers (1 + 2 + 3 + 4 + 5 + 6) you get 21. These are all the numbers on a die, so you could say it has some significance in craps and sic-too.
Also, did you know that there are 21 letters in the Italian alphabet?
What´s So Great About 21?

21 in the World´s Religions
Twenty-one is seen as a pretty wicked number in many religions- in Judaism in particular. When the children of Israel left Egypt they held 21 big rebellious events as they travelled and wandered through the wilderness. In fact, 21 is up there with 13. The apostle Paul wrote about 21 sins which good people should strive to avoid including blaspheming and disobeying your parents.
Having said that, 21 is also seen as a number of perfection being the product of 2 other important numbers: 3 x 7. You can spin this number both ways, in other words- it´s either very wicked, or very holy. One group of numbers that is talked about is 13 (unlucky in the west), 8 (lucky in the east) and 21 (the sum of both). Of course, we are talking of properties that people have assigned to these numbers over the years- they have no basis in scientific fact, but we always fine it interesting to dig out these relationships.
