In roulette, opposite numbers refer to pairs of numbers that are positioned directly across from each other on the roulette wheel. Understanding these opposite number pairs can be helpful for certain betting strategies and wheel tracking methods.
The standard European roulette wheel has 37 numbers （0-36） arranged in a specific pattern. Here is a complete list of opposite number pairs on a European roulette wheel: 
0-32, 26-15, 3-24, 35-12, 28-7, 19-4, 18-29, 21-2, 25-17, 34-6, 27-13, 36-11, 30-8, 23-10, 5-20, 16-33, 1-31, 14-22, 9-27
For American roulette wheels with 38 numbers （0, 00, 1-36）, the opposite number pairs are slightly different due to the additional double zero. The arrangement ensures that high and low numbers, as well as red and black numbers, are distributed as evenly as possible around the wheel.
Many experienced players use the concept of opposite numbers in their roulette strategies. Some believe that if a number hits, its opposite number has a higher probability of hitting next. However, it\“s important to remember that each spin in roulette is independent, and no betting system can overcome the house edge in the long run. |
