What is an Inside and Outside Bet in Roulette?

Published on January 3rd, 2009 8:58 pm EST


If you have been spending any time at an online casino recently, then you have probably come across the terms "inside bet" and "outside bet" during your play. If you don't have any clue what these two terms mean, then don't worry - the Roulette King has your back, and will walk you through the explanations.

"Outside bets" have better odds of winning, but will give you a lower payout.

"Inside bets" are the exact opposite - you have a much smaller chance of winning, but the payout is much larger if you do win.

There are six different types of "inside bets", including:

Straight-up, Street, Split, Corner, Six Line and Trio

The "inside bet" with the longest shot of winning is the "Straight-up". This is exactly how it sounds - you are betting on one number. For instance, you might put your money down on Black 29 - if the ball lands in Black 29, then you win.

The "Split" is up next. With a "split" bet, you are placing a bet on two adjoining numbers - for instance, 32 and 33.

The "Street" and "Trio" bets are next up. With a "street" bet, you are betting on all three numbers in a single horizontal line, such as 10/11/12 or 22/23/24. With a "trio" bet, you are placing a bet on either 0/1/2 or 00/2/3. These are the only combinations in which the "trio" bet applies.

After that, you have the "corner" bet (this is also called the square bet). With this bet, you are betting on four different numbers that are in a square layout - such as, 25/26/28/29.

Lastly you have the "Six Line" bet. Think of this as two Street bets combined into one. In a "six line", you might bet on 16/17/18/19/20/21.

These are the "inside bets". Now, the "outside bets".

There are also six different types of "outside bets". They are:

1. 1 to 18. You are betting on the numbers 1 through 18.

2. 19 to 36. You are betting on the numbers 19 through 36.

3. Red or Black. You are betting on either black or red showing when the roulette ball has found its new home.

4. Even or Odd. You are betting on the number being either even or odd.

5. Dozen Bets. You are betting on one of the three possibilities: 1-12, 13-24 or 25-36.

6. Column Bets. Similar to a vertical bet, except this includes all of the numbers down a vertical line on the roulette board. For instance, 1/4/7/10/13/16/19/22/25/28/31/34.

There you go - inside and outside bets explained. Best of luck at the tables!
