A roulette bet placed on specific numbers within the main grid of the betting layout. These bets are considered higher-risk due to their lower probability of winning but offer higher payouts compared to outside bets. There are also different types of inside bets, including:
- Straight-Up Bet: A bet on a single number, offering the highest payout of 35 to 1.
- Split Bet: A bet on two adjacent numbers, paying out at 17 to 1.
- Street Bet: Covers three consecutive numbers in a row, paying out at 11 to 1.
- Corner Bet: A bet on four numbers that intersect, paying out at 8 to 1.
- Line Bet: Covers six numbers across two adjacent rows, paying out at 5 to 1.
- Five Bet (in American Roulette): A bet on 0, 00, 1, 2, and 3, which is not commonly used in European Roulette.
Inside bets tend to offer higher payouts compared to outside bets, but they are also riskier due to the lower probability of winning on an individual number or a small group of numbers.
