Arbitrage vs +EV vs Promo Hacking: How to Guarantee Profit from Sportsbooks Using Math

Most people think sports betting is just gambling. And for most, it is.

They deposit $100, make a few bets based on gut feeling or loyalty to their favorite team, and hope for the best.

But smart bettors don’t gamble. They profit—by leveraging math, market inefficiencies, and promotions.

And thanks to tools like OddsJam, you don’t need to be a math genius or pro handicapper to do it. You just need a bankroll and a willingness to follow a system that’s mathematically guaranteed to win over time.

In this guide, we’ll break down the three most powerful sportsbook strategies:

  • Arbitrage Betting
  • +EV Betting (Positive Expected Value)
  • Promo Hacking

Let’s explore how they work, how they differ, and how OddsJam makes it all one-click simple.

Arbitrage Betting: Risk-Free Profit from Odds Discrepancies

Arbitrage betting (or “arbing”) is the practice of betting on all outcomes of a game using different sportsbooks—so no matter who wins, you lock in a profit.

Example:

  • FanDuel: Team A +110
  • DraftKings: Team B -105

Using OddsJam, you’d spot that this combo creates an “arb.” You bet the right amount on both sides, and you’re guaranteed to win slightly more than you wagered.

  • Risk-Free
  • Guaranteed Profit
  • Great for beginners

OddsJam scans every book and automatically shows these arbs in real time. Even better? With One-Click Bets, it opens the sportsbook tab for you and auto-loads the exact bet, calculating your ideal stake based on your bankroll. It’s plug-and-play arbitrage.

+EV Betting: Let the Math Work in Your Favor

+EV stands for positive expected value. It means the odds you’re getting are better than the true odds, giving you a long-term edge.

If you place hundreds of these +EV bets, your profit will grow even if you lose a bunch of them—because you’re betting like a casino.

🎯 Think of it like counting cards in blackjack.
You won’t win every hand—but you’ll win more than you lose, because the edge is yours.

How OddsJam Helps:

  • Calculates true no-vig odds for every game (removing the sportsbook’s hidden fee)
  • Flags bets where the odds offered are better than fair
  • Displays your expected ROI right next to the bet
  • One-Click Bets loads the book + bet for you
  • Tracks every wager for performance analysis

Example: If the fair (no-vig) odds of a team winning are +100, and a sportsbook offers +110, that’s a +EV bet. You’re betting $1 on something worth more than $1.

With OddsJam, you don’t have to calculate anything—it tells you when you have an edge and how much to bet.

Promo Hacking: Turn Free Bets into Real Cash

Sportsbooks are desperate for your business. That’s why they offer juicy promos:

  • “Bet $5, Get $150”
  • “$100 Risk-Free Bet”
  • “First Deposit Match”

What most people don’t know? These can be converted into real, guaranteed profit using a method called promo conversion.

How It Works:

  • Place one side of the promo bet on one sportsbook
  • Hedge the other side on a second sportsbook
  • No matter what happens, you extract 80–90% of the promo’s value in cash

OddsJam has a Promo Optimizer Tool that shows:

  • The most efficient way to use your bonus
  • The hedge bet needed
  • How much profit to expect
  • Perfect for new users
  • Zero risk
  • Works with nearly every sportsbook

One-Click Betting + Auto-Tracking = Effortless Execution

OddsJam isn’t just a search engine for smart bets—it’s an execution tool.

Once you find a +EV or arbitrage bet, you can:

  • Click once, and a new tab opens to the exact sportsbook
  • Your bet is pre-loaded with the right line and stake
  • OddsJam auto-calculates your ideal bet amount based on your bankroll
  • Once placed, it’s automatically tracked in your dashboard for performance monitoring

No spreadsheets, no mental math, no missed opportunities.

Isn’t This Gambling?

Let’s be clear:

  • You’re not “guessing” who will win
  • You’re not hoping for a hot streak

Instead, you’re using data to make bets where the math is in your favor.

If you love sports:

You’ll still have bets to root for—but instead of being the “degenerate gambler,” you’re the one running the system.
You’re the casino, not the customer.

If you just want a side hustle:

You can treat it like a math-based trading strategy. You don’t have to love sports—you just need to click smart buttons and let the edge work for you.
