Today, in order to bet on sports, there is no need to stand in line at a bookmaker and fill out lines. Thanks to the internet, players today can track bets and the projected winnings at several bookmakers at once. All bookmakers monitor each other's odds and use the same methodology for constructing them. However, despite this, there are still periodically discrepancies in their quotes. "How can this be used?" you will ask. Next we will look at how to earn from sports betting using the difference in bookmakers' odds.


An arb is a series of bets at separate bookmakers. The bets are selected in such a way that a loss at one bookmaker is fully covered by a loss at another.

There are two types of arbs.
A simple arb involves a bet on the same sporting event, but with the opposite outcome.
A complex one.
Bets on sporting events are placed at different bookmakers. The bets are placed on three or more outcomes of one event.

A distinctive feature of an arb is its lifespan. As a rule, a player has from 10 to 15 minutes to catch an arb and place a bet. Bookmakers themselves are not too fond of arbs, since this type of betting has no risk. Usually bookmakers lower the odds, after which the leverage of the bet decreases and the profit tends toward zero.
The main risks when using arbs
Changes in odds.
The odds at bookmakers change all the time. Because of this, seasoned players recommend working with those arbs where the odds do not change often for a match or score.
Account limiting.
Small bookmakers, upon detecting a player using an arb, may limit the account. The reason is the unwillingness to incur losses.
Personal mistakes.
Given that arbing requires making decisions in the shortest possible time, mistakes are simply inevitable. The best way to reduce the number of such mistakes is to analyze the quotes, choose interesting matches in advance, and analyze the odds at an early stage.
Cancellation of bets.
Since the odds are set by employees, the human factor cannot be avoided. For this reason, bets may be canceled. However, it is worth considering that decent bookmakers do not cancel bets. If you encounter a canceled bet - that is a reason to choose another bookmaker.
