Over time odds and evens should come up with roughly the same frequency. However, by keeping track of a few hundred spins you can identify if there is a slight trend towards odds or evens. Simply make two columns and tally a check mark for each odd or even number the ball lands on. After 200-300 spins, if you have more tallies on one side then the other, it means the ball is currently favoring that category - odds or evens. Of course, the croupier should ensure an exactly fair and random bounce of the ball to keep the casino's edge. But minor short-term trends do sometimes appear. Keeping track for a reasonable sample can reveal these to you.
