Sector targeting can be a viable strategy on certain roulette wheels, as it involves focusing bets on specific areas of the wheel, such as groups of numbers or particular sectors. This approach takes advantage of the physical characteristics of the wheel and the distribution of outcomes, potentially increasing the chances of hitting a winning number within the targeted areas. Successful sector targeting relies on careful observation and an understanding of the wheel's mechanics, as well as considering factors like biases or patterns that may develop over time.
