If you’re feeling lucky, you might want to go for an inside bet. This refers to bets on specific numbers and sets of numbers on the inside of the roulette layout. Inside bets have a lower chance of winning, but payout more when they do. The house edge on inside bets is the same as on outside bets. Examples of inside bets include:
Straight-up - The payout will be 35 to 1 (with a percentage chance of 2.7% in European roulette and 2.6% in American roulette) as you are betting on one specific number out of 2.. Also called a single-number bet.
Split - The payout will be 17 to 1 (with a percentage chance of 5.4% in European roulette and 5.3% in American roulette) as you are betting on two adjacent numbers.
Street - The payout will be 11 to 1 (with a percentage chance of 8.1% in European roulette and 7.9% in American roulette) as you are betting on a row of three numbers (i.e. 19, 20, 21).
Corner - The payout will be 8 to 1 (with a percentage chance of 10.8% for European roulette and 10.5% for American roulette) as you are betting on four numbers by placing your chip in the corner that joins them all together (essentially the centre of four numbers). This is also called a square bet or quarter bet.
Basket - The payout will be 6 to 1 (with a percentage chance of 13.2% in American roulette, this bet is not found in European roulette) as you are betting on five numbers (i.e. 0, 00, 1, 2, 3).
Line - The payout will be 5 to 1 (with a percentage chance of 16.2% in European roulette and 15.8% in American roulette) as you are betting on two adjoining rows of numbers (six numbers in total). This is also called a line bet.
