If you prefer a simple live roulette strategy, then a non-progressive system is the way to go. This strategy allows you to either wager a stable base amount, just as in the case of a flat system, or change your wager amounts as you deem fit. However, this sounds like something other than a betting strategy, as it basically allows you to do anything you please.
An example is Neighbour bets, whose concept is to split a bet across five consecutive numbers on the roulette wheel. If you miss your number, the ball has a higher chance of landing in one of the adjacent pockets.
Flat Betting Systems
Flat betting involves wagering a fixed amount each round, regardless of the outcome. This is a safer approach for most players since the odds are always against you, as reflected by the pocket “0” on the roulette wheel. Statistically, you are bound to lose if you continue to play at a roulette table. The only advantage there is that you can get an early win on an inside bet, which will give you a good profit.
An example is the James Bond strategy, where you cover half the numbers on the roulette table with bets. In doing this, you’re basically playing the odds of roulette, as there’s a 50% winning chance, not forgetting the “0” pocket.
