Roulette Calculator calculates probability of the next spin in Roulette. So it is a kind off roulette prediction (not roulette cheating). And you do not need to remember if you have long series of Color, Pair, Column, Twelve or Eighteen.

This is a first version, new features will be added.

How it works: Each number means the probability that in next spin you'll got that Color, Pair, Column, Twelve or Eighteen.

Black or Red ?
Probability that you'll got Black Color in 5 consequent spins (series of 5 Black):
18/37 power(5) = (18/37) * (18/37) * (18/37) * (18/37) * (18/37) = 2,7249 %

First Column ?
Probability that you'll got First Column in 4 consequent spins (series of 4 same Columns):
12/37 power(4) = (12/37) * (12/37) * (12/37)* (12/37) = 1,1064 %

Be careful, you'll get series of 11 consequent BLACK or RED colors in each Casino nearly every day. Sometimes even longer series :)

Roulette is a good game for fun and sometimes also to win money :-), but..
