Key:
 Blue bets = outside bets. These are the bets that cover large, fixed sections of the table. These probability of winning with these bets is greater, but they have lower payouts.
 Green bets = inside bets. These bets cover specific numbers on the table depending on where you place your chips. The payout for inside bets is bigger, but the probability of hitting is lower.
Below is a quick overview of all the different types of bets and odds that can be made in roulette.
There is also a small image accompanying each bet to highlight how to place each of the bets at the table. Some of these bets you may well have previously overlooked, so pay attention!
The following list is ordered by the payout of each roulette bet, starting with the lowest payouts and moving to the bigger payouts as you scroll down.
 Payout is in orange.
 Probability of each bet winning is in blue (assuming a singlezero European table is used).
Outside bets
Outside bets refer to bets made on types of numbers on the roulette wheel or large sections of the roulette table.
These bets have the lowest payouts, but the highest probabilities of success.
Red / Black  1:1 (48.65%)
Color bet
Payout  1:1 

European Probability  48.65% 
American Probability  47.37% 
Total Numbers  18 
Numbers Covered  Black = 2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35 Red = 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36 
A color bet is a very popular bet, and gives odds of 1:1. So lets say for example you bet $5 on red, and after spinning the wheel the ball lands on red. You will get your $5 back, as well as an additional $5 in winnings, returning $10 in total.
Even / Odd  1:1 (48.65%)
Payout  1:1 

European Probability  48.65% 
American Probability  47.37% 
Total Numbers  18 
Numbers Covered  Even = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36
Odd = 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35 
Similar to the color bet, the even or odd boxes offer the same payouts with equal odds for hitting even or odd as there are for hitting red or black. Unfortunately, the green 0 does not count as either even or odd.
Low (118) / High (1936)  1:1 (48.65%)
Payout  1:1 

European Probability  48.65% 
American Probability  47.37%

Numbers Covered  Low = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18
High = 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36 
These bets split the table in half, with one bet allowing you to bet on all of the lower half of the numbers (118) and the other half allowing you to bet on all of the higher numbers (1936). Also known as the low bet and high bet.
Dozen  2:1 (32.43%)
Payout  2:1 

European Probability  32.43% 
American Probability  31.58% 
Total Numbers  12 
Numbers Covered  1st Dozen = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 2nd Dozen = 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 3rd Dozen = 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36 
The dozen bet allows players to bet on 3 different sections containing 12 numbers, which are; 112, 1327 and 2836. This bet offers slightly higher odds (2:1) than an even money bet, but the chances of winning on one spin are a little lower.
Column  2:1 (32.43%)
Payout  2:1 

European Probability  32.43% 
American Probability  31.58% 
Total Numbers  12 
Numbers Covered  1st Column = 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34 2nd Column = 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35 3rd Column = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36 
The column bet is very similar to the dozen bet, but instead splits the table into 3 sections lengthways rather than sideways. Each of these bets also offer odds of 2:1, just as with the dozen bets.
Inside bets
Inside bets refer to bets made on specific numbers or small groups of numbers on the roulette wheel.
These bets have the highest payouts, but the lowest probabilities of success.
6 Number  5:1 (16.22%)
Six line bet, Double street bet
Payout  5:1 

European Probability  16.22% 
American Probability  15.79% 
Total Numbers  6 
Numbers Covered  e.g. 10, 11, 12, 13, 14, 15 
This particular bet is not always available at online casinos, but can still be played at the majority of them. Often overlooked by many novice players, this bet allows you to bet on 6 numbers at a time via a bet split between two adjacent rows.
5 Number  6:1 (13.16%)
Note: This bet can only be placed on American roulette tables (ones with the green 00).
Five number bet, Top line bet, Basket bet, The worst possible bet you can make on any roulette table
Payout  6:1 

European Probability  n/a 
American Probability  13.16% 
Total Numbers  5 
Numbers Covered  0, 00, 1, 2, 3 
The five number bet holds the title for the worst bet in roulette. The house edge for this bet is 7.89%, and it's the only bet to have a bigger (worse) house edge than any other. Every other bet on a doublezero roulette has a house edge of 5.26%.
If you're playing American roulette (which you shouldn't be anyway), avoid this bet.
4 Number  8:1 (10.81%)
Corner bet, Square bet
Payout  8:1 

European Probability  10.81% 
American Probability  10.53% 
Total Numbers  4 
Numbers Covered  e.g. 11, 12, 14, 15 
Also known as a square bet or corner bet. The 4 number bet allows you to bet on 4 adjoined numbers at a time. The chances of hitting any of these numbers is relatively low, but there is a decent payout for when you get lucky.
3 Number  11:1 (8.11%)
Street bet, Line bet
Payout  11:1 

European Probability  8.11% 
American Probability  7.89% 
Total Numbers  3 
Numbers Covered  e.g. 16, 17, 18 
This bet involves similar placement to that of the 6 number bet, except for the chip is placed on the edge of one row, rather than spread across two. This bet is also known as the street bet or stream bet.
Alternative 3 number bets.
You can also place 3number bets at the top of the table using the green zero(s). These can be placed in both singlezero and doublezero roulette, although you have an extra 3number bet in doublezero roulette courtesy of that extra 00 number.
The payouts and probability for this bet are the same for the respective roulette tables as the street bet above.
2 Number  17:1 (5.41%)
Split bet
Payout  17:1 

European Probability  5.41% 
American Probability  5.26% 
Total Numbers  2 
Numbers Covered  e.g. 22, 23 
This is where the odds start to get pretty big. A 2 number bet or split bet allows you to bet on two adjacent numbers, offering you some pretty attractive odds of 17:1 — the second biggest payout available at a roulette table.
You can place a split bet across two numbers vertically or horizontally (if that makes any sense). In the screenshot above for example, you could just as easily bet on 22&25 or 22&19 instead of 22&23.
Single Number  35:1 (2.70%)
Straight bet
Payout  35:1 

European Probability  2.70% 
American Probability  2.63% 
Total Numbers  1 (no prizes, sorry) 
Numbers Covered  e.g. 32 
The single number bet or straight bet is the big one, offering the greatest payouts at the roulette table of 35:1. Simply place your bet on one number and hope to get lucky.
Final thoughts.
So those are all of the different bets and odds of each of the bets when playing roulette online (or live for that matter). There is no restriction to how many different bets you can place at the roulette table, so go wild and see how it turns out. Just remember to enjoy yourself!
