How the Nine Bet Strategy Operates
As previously mentioned, the roulette table is split into four distinct sections, each covering nine numbers:
To cover an entire section, place bets on three streets, one unit per street. Street bets offer an 11:1 payout, and with a 24.32% chance of hitting one of the nine numbers in European roulette, this strategy can be quite effective. Here's how it works in practice:
1. Start by observing 10 spins and taking note of which numbers show up.
2. If you see that numbers from the first section (1-9) haven’t appeared often, you can place three street bets covering that area, wagering 1 unit on each street.

3. If one of your bets wins, you’ll net a profit of 9 units. After a win, revert back to your initial bet amount.
4. In the case of a loss, increase your bet by 1 unit per street, totalling 6 units (2 on each street). This progression ensures that if you win the next round, you recover the previous losses.
5. Continue this process, adjusting your bets based on the outcomes. For instance, if you lose several consecutive rounds in the first section, consider switching to a different section while continuing with the same betting progression.
Downsides of the Strategy
The system provides another approach, which is moderately progressive, by recovering after a loss or by winning some money. In any case, the major negative point is that the whole logic of the system is based on the assumption - being actually wrong - that the chances of winning increase while betting on sections which appear less frequently. Each roulette spin is totally independent of any other; therefore, there is no correlation between successive outcomes.
To make the strategy at least a little bit better, start in each first part with the smallest bet. If you lose, move on to the next section by raising the bet per street by 1 unit. Statistically, nothing is lost because probability remains 24.32%, but you do not have to follow "cold" sectors.
