It could be argued that over the course of 37 spins you are very unlikely to see all 37 numbers, meaning that some numbers should in theory show a few times and other won’t show at all.
To use this roulette system you will first spin the wheel, see what number you get, If for example number it landed on nuber 19, on the next spin you would bet on number 19.
If on the second spin you get number 9 you would bet on 19 and 9, and so on, this can be repeated for all 37 spins.
The catch is that if all 37 numbers show you will have bet 666 and won nothing.
Hope is the aim of the fame with this system as you are waiting for a lot of repeats because this will mean more winnings and less numbers to bet on.
