Roulette is primarily a game of luck, as the outcome depends on the random spin of the wheel and where the ball lands. Players cannot influence the result, and each spin is independent, with no patterns or strategies that can reliably predict or alter the outcome. While players can manage their bets and use different betting systems, these strategies do not change the house edge, making skill less relevant than in games like poker or blackjack. The randomness of each spin is the key factor in Roulette.
