If you watch a few tables in the casino you may pick up a dealer only spinning numbers from a particular part of the wheel (lets say a certain half of the wheel)
Before the dealers next spin you can quickly cover half the wheel with this simple and easy to understand betting technique without looking at the free roulette guide card on the table.
The first 18 numbers (1-18) RED and the second 18 numbers (19-36) BLACK are all neighbours and vice versa.
We also bet the two border line numbers i.e.: 10 and 32 or 0 and 32
This way you can bet 20 numbers quickly before the dealer shouts "No More Bets Please"

Good Luck!
