Unlike jackpot and coinflip the results of roulette are predetermined, meaning we cannot change them or manipulate with them. This is an important distinguishment because in roulette you are playing against the site.

At the start of each day random.org generates a new secret for the day, this is then coupled with a round number, which is in ascending order, and with these two values we determine the roulette color for the round. The currents day secret is always hidden so that you cannot predict the game outcomes, it's shown only after a new secret is in use.
