Sports Betting Guide — Understanding Juice and Chalk


Have you ever heard someone talk about the word “juice,” and the first thing that comes to your mind is apple or orange? What about “chalk?” If your first thought was a blackboard at school with your teacher writing names of presidents on it, don’t feel upset if you were close, but not quite there.

You’re not out of the loop if you don’t understand yet, because it can be hard to follow along in the sports betting world when people talk.

Here’s a closer look at what exactly juice and chalk mean in the sports betting world.

Understanding Juice

“Juice” in the betting world can also be known as the “vig.” Whether the term juice or vig is used, it refers to the edge the house gets in taking your bet, and it’s also what keeps bettors from being winners in the long run.

When you bet on a “point spread” game, you’ll notice that beside each team, there is likely a -110. This indicates that it will cost you $110 to win $100. So when both teams have a -110 beside them, the sportsbook is winning $10 every time they take a bet on each side of a matchup.

The bottom line is that the -110 says that you must pay a 10% fee no matter if you want one team or the other. So this is why it was stated that in the long run, most bettors can’t become winners, because on most games you are paying a 10% fee and the sportsbook is profiting off of that, making it more difficult for the bettor to win over time.

Understanding Chalk

Another common sports betting term is “chalk,” or “chalky.”

“Chalk” means someone is a heavy “favorite” in a matchup. The term originates from the time when sports betting was done on a chalkboard. The odds were written out on the board, just like in school. The name is still used today, despite the computerization of odds.

But in this case, the bookies took bets, and the favorites were bet more often, and things would get erased and updated and written over. It’s the favorites that took the most action, and had all the “chalk” on the chalkboard.

Now that you’ve learned a few more terms, you can place “units” on games and start keeping track of how you are doing. Thankfully, no chalk is required.

Bet Responsibility

Once you’ve figured out the “money line” and the “point spread” and are ready to bet, you should figure out an amount you are comfortable playing with. You’ve heard the saying to always gamble responsibly, which is no different here.

Always play within your means. So when figuring out how much you should wager on a game, you should always have an amount in your mind (or account) that you are ok if you lose. A “unit” compares your win amounts with other bettors while removing money entirely from the situation. Let’s be honest; each sports bettor has a different bankroll than the person beside them, so this way, you can track your results without a dollar amount attached to it.  So if you typically bet $100 a game, then $100 is one “unit” for you. If you bet $25 a game, then $25 is one “unit” for you.

This allows you to track your record without tracking dollar figures. It’s fair to say that most casual sports bettors don’t put aside a certain amount and say they will bet with it. They typically bet when they see fit, so it’s always good to pick a typical bet size and stick with that.
