A line bet in roulette, also known as a "six line bet" or "double street bet," is a wager placed on two adjacent rows of numbers, covering a total of six numbers. Players make this bet by placing their chips at the outer edge of the two rows on the betting layout. For example, a line bet can cover the numbers 1, 2, 3, 4, 5, and 6 or any other combination of two adjacent rows. This type of bet offers a payout of 5 to 1, providing players with a way to cover multiple numbers while still having a decent potential return.
