Inside Bet

Roulette

A category of roulette wagers placed on the numbered grid portion of the betting layout, as opposed to the “outside” perimeter where the broader category bets are located. Inside bets include straight-up (single number), split (two numbers), street (three numbers), corner/four numbers, six-line (six numbers), and trio (0-1-2 or 0-2-3) bets. Inside bets generally offer higher payouts but lower probability of winning compared to outside bets. The maximum bet limits for inside bets are typically lower than outside bet limits, as a single winning inside bet can result in a substantial payout liability for the casino.

In practice

Surveillance should monitor inside bet patterns, as players attempting to exploit wheel biases often concentrate their wagers on specific sectors of numbers rather than spreading bets randomly.
