When someone bets on sports, there is normally one factor that can make or break the bet: the score. However, there is more than one type of betting, and many people don’t know the differences. Here we are going to discuss the differences between the types of odds, examine when to use them, and help you become a smarter sports bettor.

## The Spread

The first type of betting is known as “point-spread” or “line-spread” betting. This is where the odds of one or more teams winning or losing a game are given. The spread can be calculated by subtracting the betting line for the game from 100 points. For example, a betting line of +200 might mean a 200-point advantage for the home team in a given game. If a football team is a 7-point favorite, the spread would be calculated as follows:

- 7 points x 2 = 14
- 100 – 14 = 86
- 86 ÷ 2 = 43.5
- 43.5 x 2 = 87.5
- 87.5 – 100 = -97.5
- -97.5 x 2 = -194.5
- 194.5 – 200 = -96.5
- -96.5 x 2 = -191.5
- 191.5 – 7 = 184.5
- 184.5 x 2 = 368.5

In the above case, the “line” would be (+7/-200). The “point” would be the 100-point line for the game, which in this case is the betting line.

## The Reverse Line-Spread

Another type of betting is known as the “reverse line-spread” or “short-point-spread” betting. This is where you put money on the opposite of what you think will happen. For example, if you were aware that a team was a big favorite to win a particular game, you could bet on the underdog or co-favorite to win. This would be a form of short-point-spread betting. The calculation would be the same as the point-spread, except you would add the point spread to the betting line instead of subtracting it.

## Fractional Odds

Another type of odds is known as “fractional odds.” These are where the odds of an event are not whole numbers but rather a fractional amount. For example, if you are betting on the Superbowl and you know that the Patriots have a 20% chance of winning, your fractional odds would be 20/1 or 2-to-1. This is a popular form of odds with American sportsbooks. Fractional odds are often useful for NBA and NHL games, where you can’t place an exact bet. For example, if you were to bet $100 on the Toronto Maple Leafs versus Boston Bruins, you might receive $20 worth of commission, but you would also have to pay $80 worth of bets, because the odds of the Maple Leafs winning are 1.2. This is why you would use fractional odds instead of an even or odd number to represent the probability of an event.

## Odds Or Evens

The last type of odds we will discuss is known as “odds” or “evens.” This is where you get either odd or even numbers to represent the probability of an event. These are the most popular types of odds. If you are a fan of NBA games and you want to make sure you get the best odds available for the given game, you would use even odds. Some sportsbooks even provide a mobile app where you can access odds for virtually any sporting event, making them easily accessible anywhere.

## Odds Vs Evens

Using odds and evens to represent betting probabilities creates a major problem for people who like to keep track of their odds. Odds and evens are often used together in sets of two, with one being twice as likely as the other. One easy way to keep track of them is using a fraction bar. So if you have an odds column and an evens column next to each other, and you want to change the odds to fractions, you would do so in the following manner:

- 1.5 or ¾
- 1/2
- 1
- 2
- 3/2
- 3/1
- 1.33
- 5/2
- 5/1
- 4/1
- 7/1
- 9/1
- 11/1
- 13/1
- 15/1
- 17/1
- 19/1
- 21/1
- 23/1
- 25/1
- 27/1
- 29/1
- 31/1
- 33/1
- 35/1
- 37/1
- 39/1
- 41/1
- 43/1
- 45/1
- 47/1
- 49/1
- 51/1
- 53/1
- 55/1
- 57/1
- 59/1
- 61/1
- 63/1
- 65/1
- 67/1
- 69/1
- 71/1
- 73/1
- 75/1
- 77/1
- 79/1
- 81/1
- 83/1
- 85/1
- 87/1
- 89/1
- 91/1
- 93/1
- 95/1
- 97/1
- 99/1

As you can see, this notation can get rather messy. Fraction bars also make it harder to do fractions in sets, because it is hard to keep track of what is a fraction and what is an entire number. Odds and evens are often used together in sets of two, which makes the notation even more complicated. Instead of using fraction bars, many people just write out the fraction, separating it with a comma or a “⅓” of a bar.

The odds column shows what you are paying to win the game. For example, if you bet $100 on the Oakland Raiders and you win, your $100 would be refunded, and you would keep the $50 you put down, resulting in a profit of $50. The evens column shows what you are receiving in return for your bet. For example, if you bet $100 on the New England Patriots, and they win, you would receive $200, and your original $100 would be refunded, giving you a profit of $200.

When someone bets on sports, there is normally one factor that can make or break the bet: the score. However, there is more than one type of betting, and many people don’t know the differences.
