The roulette wheel is divided with two colors, black and red both have their own 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 total of all the black numbers is 334 and the sum of the red numbers is 332. These numbers consist of odd and even, with 10 even black numbers and 8 even red numbers. Naturally there are 8 odd black and 10 odd red.
Numbers like 11, 13, 17, 29, 31 and 5 are the 5 black prime numbers and numbers like 1, 3, 5, 7, 23 are the 5 red prime.
The combinations of these numbers are quite strange because they are not balanced and they dont show it they are random but they could be. If numbers were ran from 1 to 36 with alternating black and red colors, or if all the red numbers were even and all the black were odd, it is not possible to tell if these were random or not.
The point is that any sequence of numbers from 0 to 36 that are generated randomly is just like any other sequence. In the National Lottery you are more likely to win with the numbers 1, 2, 3, 4, 5, 6 as you are with any other sequence. Everybody knows about this but very few beleive it works.
It has a big impact is a string of numbers generated by an online casino which is hosting a roulette games is random or not. The casino might be accused of cheating when the numbers are other than random.
There might be a pattern that a player can use to increase the chances of winning. However, testing if the numbers generated in an online roulette game is random is never easy.
One way is to look for any patterns within the numbers by producing a bitmap of the numbers and use look at the bitmap to see if there are emergent patterns. This has proven to be effective, with many format statistical methods that can examine data for non-random patterns and casino random number generators that are frequently audited and must pass these tests.
