Roulette looks complex because the table is covered in numbers, but every bet fits into two groups: inside bets and outside bets.

Inside bets cover specific numbers or small groups, pay more, and win less often. Outside bets cover large groups like red or black, pay less, and win more often.

The house edge comes from the zero, or zero and double zero on American wheels. European wheels, with a single zero, give players better odds.

No betting pattern changes the odds of the next spin. Choose bets you enjoy, keep stakes small, and set a session budget. Set limits and never bet what you cannot afford to lose.
