A Complete Guide to Roulette Betting

Online Roulette Betting

If you're thinking of playing roulette online, however big or small the stakes, you'll need to get up to speed on how roulette betting works. Blindly putting wagers down without having a grasp of the basics can lead to a serious dent in your bankroll. Learn which bets offer the best odds to win and have the highest payouts at any Canadian online casino.

Your Main Bet Options

Roulette bets are divided into two main types: inside or outside. While each offers different odds and payouts, both are subject to the same house edge. American roulette tables have a 5.26% edge and European tables offer a 2.70% edge. Even-money bets placed at European tables with French rules are only subject to a 1.35% house edge.

Inside Roulette Bets

These are the bet spaces located inside the table. Although the inside bets might have higher payouts, they are much less likely to win on any given spin. That said, there's nothing that matches the thrill of hitting a single number for a 35/1 payday!

Bet Name Bet Description Payout American European
Straight Up A wager on a single number: 1-36. 35/1 5.26% 2.70%
Split A wager on the line between two numbers 17/1 5.26% 2.70%
Street Also called a 'row' bet, this is a wager on three connected numbers such as 6, 5, 4. 11/1 5.26% 2.70%
Trio A wager on a corner connecting three numbers such as 0, 2, 3. 11/1 5.26% 2.70%
Corner Also called a 'quad' bet, this is a wager on the corner connecting four numbers such as 2, 5, 1, 4. 8/1 5.26% 2.70%
Double Street Also called a 'line' bet, this is a wager on the line between intersecting rows covering six numbers. 5/1 5.26% 2.70%
Basket A wager on 0, 00, 1, 2, and 3. 6/1 7.89% n/a

Outside Roulette Bets

Outside bets are the best choice for beginners. Particularly, even-money bets including even/odd, black/red and high18/low18. These pay out 1/1 but provide a nearly 50-50 chance to win.

Bet Name Bet Description Payout American European French
Even/Odd A wager on eighteen even or odd numbers. 1/1 5.26% 2.70% 1.35%
Black/Red A wager on eighteen black or red numbers. 1/1 5.26% 2.70% 1.35%

Low 18 This wager covers numbers 1-18. 1/1 5.26% 2.70% 1.35%
Column A wager on twelve,non-sequential numbers in a column. 2/1 5.26% 2.70% n/a
Dozens A wager on twelve sequential numbers in a row. 2/1 5.26% 2.70% n/a

A Closer Look at Roulette Bets

Inside Bets

The inside bets in roulette are, quite simply, found on the 'inside' of the table. They offer the lowest chance to win and the highest payouts. The different types of inside bets are explained below.

Straight Up


The straight up bet is one of the simplest wagers you can make in roulette. These are bets on what the number of the very next spin will be.You can either place bets on multiple single numbers at a time or combine them with outside bets.


Hitting a single number is obviously pretty hard with only a 2.63% – 2.70% chance to win. However, when you win with a straight up bet, you can take advantage of the game's highest payout: 35/1. In other words, for a straight up bet of 1 chip, you would receive 35 chips plus your original chip back on a win.

Play Free Games



The split bet is a double straight up bet. You just have to put your chip stack between the two numbers you want to bet on. If either number is shown, you win.


Split bets have the second highest pay out: 17/1. There is only a 5.26% – 5.40% chance that this type of inside bet will win each spin.



Taking inside bets to the next level, the street bet allows you to bet on a row of three numbers. Put your chips on the far line of a row, and you'll have marked this bet. See the top row of our sample layout.


Now we start to see just a little bit of action as this kind of bet wins 7.89% – 8.11% of the time. It pays out 11/1.



This bet also covers three numbers at a time when chips are placed at intersections connecting numbers on the table.


Like the street bet, the trio also has the potential to win 7.89% – 8.11% of the time and pays out 11/1.



To make a corner bet, put your chip stack at the intersection (or corner) where four numbers meet on the layout.


This type of bet offers a 10.53% – 10.81% chance to win with an 8/1 payout. So, if you bet 1 chip on a corner bet space and the next spin results in a win, then you will receive 8 chips plus your original chip back.

"Many casual gamblers think roulette betting is rather black and red, but nothing could be further from the truth. From inside to outside bets, straights and corners, streets and splits, online roulette has an abundance of betting options."

Double Street


The double street is just what its name implies - a bet on two 'streets' or rows. You place chips on the far side directly between the two numbers at the end of their respective streets.


Covering six numbers under a single wager gives a double street bet the odds to win of about 15.78% – 16.22% of the time. It pays out 5/1.

Basket / First Five


The basket bet is a wager on 0, 00, 1, 2 and 3. Since it relies on the 00 pocket, it can only be used with American wheels.


TThis bet has a 13.16% – 13.51% chance to win and pays out 6/1. However, with a house edge of 7.89%, it sticks out like a sore thumb as the single worst bet in roulette.

Outside Bets

Unlike inside bets, o, outside bets cover larger portions of the wheel. This is where you will find even-money bets which pay the lowest but give the highest chance to win. The next highest chance bets include columns and dozens. Both cover about a third of the numbers and payout 2/1.

Even / Odd


These bets are very simple to make. Just look for the spaces on the layout labeled 'Even' and 'Odd.' Put your chip stack on whichever space you'd like, sit back and watch the wheel spin. There, told you it was easy, didn't we?

Put your chip stack on whichever space you'd like, sit back, and relax. This bet has the standard 5.26 percent house edge.


Because nearly half of the numbers are even and nearly half are odd, one of the bet spaces is going to win almost every spin. 0 and 00 aren't included in this bet giving the casino its edge. So, this type of bet has a 47.37% – 48.65% chance to win but only pays out 1/1.

Red or Black


This bet is also an even-money wager that covers eighteen numbers at once. Placing a stack on red will cover all the red pockets on the wheel. Placing a stack on black will cover all black pockets. 0 and 00 are green and give the house its edge.


Since most pockets are either red or black, , one of these spaces will win most of the time. Each bet has a 47.37% – 48.65% chance of winning and pays 1/1.

Betting on red or black is one of the most basic roulette bets making it perfect for beginners. Below, you can see what color each numbered pocket is.

Red 1 3 5 7 9 12 14 16 18 19 21 23 25 27 30 32 34 36
Black 2 4 6 8 10 11 13 15 17 20 22 24 26 28 29 31 33 35

High 18


If you bet on high 18, you are wagering that the following spin will result in a pocket numbered 19-36.


Like any even-money bet, the chances of winning are the best of any other bet option, and the payout is the lowest at 1/1. This is another great choice for new Canada players taking online roulette for a spin.

Low 18


As the name suggests, low 18 is the opposite of high 18. It wins when the ball lands in a pocket numbered 1-18.


Because this covers nearly half of the wheel-head,it will win around half of the time and pay out 1/1.



The column bet is like the street bet, but it covers twelve numbers in a column instead of three in a row. There are three columns to choose from. Have a look at the numbers each choice covers below.

Column 1 1 4 7 10 13 16 19 22 25 28 31 34
Column 2 2 5 8 11 14 17 20 23 26 29 32 35
Column 3 3 6 9 12 15 18 21 24 27 30 33 36


Betting on a column covers nearly one-third of the wheel for a 31.58% – 32.43% chance to win and pay out of 2/1. Since it should win around once every three spins, this outside bet offers much less risk than any of the inside bets.



The dozens bet, as the name implies, lets you bet on twelve numbers at a time. However, instead of betting on numbers that lie in the same column on the table, you bet on a dozen numbers in sequential order.

These numbers are broken up into three separate dozens:

First Dozen 1-12
Second Dozen 13-24
Third Dozen 25-36


Just like column bets, these have a nearly 1 in 3 chance to win and pay 2/1.

Picking the Right Bet for You

You now have all the information you need to choose which bet suits your strategy best. Inside bets are best for Canadian players that enjoy a high risk, high reward gaming experience with infrequent, big-money wins. Outside bets are low risk, low reward and work best for players that enjoy more frequent, small wins.
