What Does -110 Mean?

The magic number in sports betting is -110 because it defines the amount required by a sportsbook to earn $100 on either side of most wagers. A bettor must lay $110 to win $100 when wagering on point spreads, which are set by oddsmakers with hopes of getting equal action on both sides.

Confused yet? Don’t be, as it’s really not that hard to understand once you get the basics of sports betting down between book and bettor.


How Live Betting Works

Live betting is the latest and greatest wagering option available at many sportsbooks now. Those books that still do not have live betting simply do not have the resources or technology capable of handling the constant updating of numbers required to keep up with the fast pace of the different sporting events covered.


Best Live Sports Betting Strategies

As live betting continues to become a much bigger phenomenon in the United States featuring more and more American sports after Europeans made it popular with soccer, the interest in handicapping and profiting from it also continue to grow exponentially.


Best Sports Betting Strategies

If you talk to any bettor at a sportsbook, they will have their own wagering tips that they use to win money. Sometimes they work, sometimes they don’t.

But the most important sports betting strategy of all is staying true to whatever system you use over the long term and not abandoning it at the first sign of a losing streak. The most successful sports bettors realize this and continue using their strategies year after year without ever questioning their logic.


Sports Betting Databases

Football bettors, office poolies, and pick'em game contestants have plenty of stats and resources at their fingertips - but how many of those stats or trends are their own? OddsShark has a huge archive of 30 years of NFL point spread data, baseball boxscore material, and much more that do-it-yourself handicappers can use for free right now.


Zig-Zag Theory

The Zig-Zag Theory is a betting system many handicappers follow that applies to all NHL and NBA best-of-seven playoff series that use the 2-2-1-1-1 format.

It is named the ‘Zig-Zag Theory’ for its propensity of momentum shifting between the home and road teams based on how each performed in the previous game. The idea is that each game in a playoff series is affected by the result of the game that preceded it.


Why the Line Moves

In the long run, sportsbooks make their money with the juice or ‘vig’ they charge for betting on each and every sporting event. When you choose a side against the spread and wager 11 to win 10, the book is essentially making a bet of 10 to win 11 on the other side. You can see how that would be a profitable model over time.


Who Sets The Line?

Understanding how point spreads work is essential in order to be a successful bettor. But thinking like an oddsmaker and setting your own lines before the opening odds are released can help you greatly and allow you to find the most value on the betting board.


What Line Moves Can Tell Us

After oddsmakers release their opening lines at sportsbooks, the betting public almost immediately reveals which side of the number they like more and moves them accordingly. But while these early line moves may show where the public money is initially going, it does not obviously tell the whole story until we can see where the closing odds end up.
