Welcome to the foundational guide for understanding sports betting terminology. Navigating matched betting successfully requires a clear grasp of key concepts. This section cuts through the jargon to give you the bare minimum you need to know, along with some extra insights to help you get started. From understanding different types of bets to deciphering odds and knowing how sportsbooks make their money, this guide is designed to equip you with the essential foundational knowledge for applying matched betting strategies. Individual results will vary and are never guaranteed.

Key Terminology

SmartStake has kept this section short. The bare minimum you need to know:

• Odds: The "price" of your bet, reflecting the probability an event is expected to occur. Odds determine your potential payout.
• Payout: The total amount of money you receive when your bet settles. This includes your initial stake plus any winnings.
• Stake: The initial amount of money that you bet. Also called "wager."
• Winnings: The "profit" from your bet. This is the total payout minus the initial stake amount.

How to Read Odds

There are two popular ways to display the odds of an event: American and Decimal. SmartStake uses American odds as the default. Choose the format that makes the most sense to you, and set the odds to that format on SmartStake and all of your sportsbooks. Keeping the format consistent across your accounts can save you time and reduce the chance of errors.

The odds of a bet reflect the "price" of an event, or the probability that your bet will win. If an event has a 50/50 chance of occurring, then the odds are even. Sportsbooks will display even odds as +100. A coin flip would be an example where the odds are even - we would expect sportsbooks to offer a bet on a coin flip at +100 odds.

The less likely something is to occur, the higher the odds. If a sportsbook is offering a bet at +300 odds, that means the underlying event is less likely to occur, but the potential payout for a win is much higher.

The more likely something is to occur, the lower the odds. If a sportsbook was offering odds for the sun to come up tomorrow, we would expect to see very negative odds, such as -10000, because the event is almost certain to happen, resulting in a very small profit relative to your stake.

At the most basic level:

• Higher odds → "This bet is not likely to win, but if it does, then my winnings will be higher since I'm taking on more risk."
• Lower odds → "This bet is probably going to win, but my winnings will be lower since I'm not risking much."

Understanding American Odds

• Positive Odds (e.g., +150): When odds are positive, the number indicates how much profit you would make on a $100 bet. So, +150 means a $100 bet would win you $150 profit, for a total payout of $250.
• Negative Odds (e.g., -150): When odds are negative, the number indicates how much you need to bet to win $100 profit. So, -150 means you would need to bet $150 to win $100 profit, for a total payout of $250.

Decimal Odds (Briefly)

Decimal odds are simpler for calculating total payouts, as they represent the total return for every $1 staked. For example, odds of 2.50 mean a $10 bet would return $25 ($10 stake + $15 profit). 1.50 means a $10 bet returns $15 ($10 stake + $5 profit).

How Sportsbooks Make Money

Sportsbooks make money by setting the odds for an event, and adding a profit percentage for themselves (called "vig" or "juice"). The sportsbooks want to balance the amount of money wagered on either side of an event, so that regardless of who wins, they keep the "juice" on the entirety of the money wagered. This is how they ensure profitability.

Let's go back to our example of a sportsbook offering odds on a coin flip. We know that the "fair" price of a coin flip is +100, since there is a 50% chance that it lands heads or tails. If there is a 50% chance that I lose my money, I should expect my money to double if I win. The fair payout on a coin flip that wins would be $200 ($100 stake + $100 in winnings).

However, you would never see a sportsbook price a coin flip at +100. You would likely see the odds priced like this:

• Heads: -110
• Tails: -110

Let's take the scenario above and pretend that you bet $100 on heads and someone else bets $100 on tails. The sportsbook has collected a total of $200 in bets. There will only be one winner — heads or tails — and the winner will be paid out $190.91 ($100 stake + $90.91 winnings). The sportsbook collected $200 and only paid out $190.91 — they get to keep $9.09 for themselves. This small margin, when applied to millions of dollars in wagers across many games every day, generates significant revenue for sportsbooks. Understanding this "vig" is important for matched betting, as it explains why a break-even scenario without a promotion is difficult to achieve.

Common Betting Markets

Understanding the different types of bets you can place is fundamental. Here are the most common betting markets:

Moneyline

• Also called: "Winner", "2-way"

The moneyline means you are betting on which team will win the game outright. The moneyline market does NOT include ties - there has to be a winner and a loser. If a game ends in a tie after regulation in sports where ties are possible (like soccer, though less common in US major sports for moneyline), the bet might be voided or settled based on specific sportsbook rules (e.g., including overtime).

Point Spread

• Also called: "Handicap", "Run line" (for baseball), "Puck Line" (for hockey)

The point spread means you are betting on a team to win or lose the game by a certain number of points (or runs, or goals). People bet the spread when there is a clear favorite to win the game outright, as it offers more competitive odds than a simple moneyline on a heavily favored team. The spread creates a handicap that theoretically evens the playing field between two teams. For your bet to win, the team you chose must cover the spread. For example, if a team is -7.5 points, they must win by 8 points or more. If they are +7.5 points, they can lose by 7 points or less, or win outright.

Total Points

• Also called: "Totals", "Total Goals" (for soccer and hockey), "Total Runs" (for baseball)

Total points means you are betting on the combined score of both teams in a given game to be over or under a specific number set by the sportsbook. By default, this usually includes overtime unless otherwise specified. Always "Watch out for sportsbooks that offer total points (regular time) separately from total points (match)," as this can significantly impact your bet's outcome if the game goes into overtime. This market is popular because you don't need to pick a winner; you just need to predict the scoring pace of the game.
