There are various types of bets you can make in Roulette, including inside bets (betting on specific numbers) and outside bets (betting on groups of numbers). Inside bets include straight-up bets (betting on a single number), split bets (betting on two numbers), street bets (betting on a row of numbers), and corner bets (betting on four numbers). Outside bets include column bets (betting on a column of numbers), dozen bets (betting on a group of 12 numbers), and even/odd or red/black bets (betting on the color or odd/evenness of the numbers).
