Roulette Wheel Numbers
The black numbers on a roulette wheel are 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33 and 35. The red numbers are 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34 and 36.
The sum of all the black numbers is 334 and the sum of the red numbers is 332. There are 10 even black numbers and 8 even red numbers. Naturally there are 8 odd black and 10 odd red.
There are 5 black prime numbers which are 11, 13, 17, 29, 31 and 5 red prime numbers are which are 1, 3, 5, 7, 23.
These number combinations are quite strange. They are not balanced and they do not give the impression of being random though of course they could be. In fact if numbers were sequential and ran from 1 to 36 with alternating black and red colours, or if all the red numbers were even and all the black were odd, it would not be possible to state categorically that these were not random.
The point of all this is that any sequence of numbers from 0 to 36 that are generated in a random manner is just as likely as any other sequence. In the National Lottery you are just as likely to win with the numbers 1, 2, 3, 4, 5, 6 as you are with any other sequence. This is a fact that everybody knows but very few people actually believe.
It does matter if a string of numbers generated by an online casino hosting a game of roulette is or is not truly random. If the numbers are other than random the casino might be accused of cheating.
Alternatively a gambler might detect a pattern in a string of numbers that they could exploit in order to increase their chances of winning.
So how do you test is the numbers generated in an online roulette game are random? This is very difficult to do.
One way is to look for any patterns within the numbers. An excellent way of doing this is to produce a bitmap of the numbers and use human beings to physically look at the bitmap to see it there are emergent patterns. This is surprisingly effective. There are many format statistical methods that can also examine data for non-random patterns and casino random number generators are frequently audited and must pass these tests.
