Moneyline
A straight bet on who wins. No margins, no handicaps — just the winner.
This guide covers what you actually need before your first wager: how to read odds, what the main market types mean, how a payout is calculated, and where the sportsbook’s margin comes from. No jargon left unexplained.
Sports betting is staking money on the outcome of a sporting event at a price set by a sportsbook. If your prediction is correct, you receive your stake back plus a profit determined by that price. If it is wrong, you lose the stake.
The price — the odds — is the single most important thing on the screen. It tells you both what you stand to win and what the sportsbook thinks the chances are.

American odds are written with a plus or minus. A minus number is the amount you must stake to win $100: −150 means risk $150 to win $100. A plus number is what you win from a $100 stake: +200 means a $100 stake returns $200 profit. Minus is the favourite, plus is the underdog.
Decimal odds are simpler: multiply your stake by the number to get the total return, stake included. 2.50 on a $100 bet returns $250, of which $150 is profit.
Fractional odds, common in horse racing, show profit relative to stake. 5/1 means $5 profit for every $1 staked.

| American | Decimal | Fractional | Implied chance | Return on $100 |
|---|---|---|---|---|
| −200 | 1.50 | 1/2 | 66.7% | $150 |
| −110 | 1.91 | 10/11 | 52.4% | $191 |
| +100 | 2.00 | 1/1 | 50.0% | $200 |
| +150 | 2.50 | 3/2 | 40.0% | $250 |
| +300 | 4.00 | 3/1 | 25.0% | $400 |
Add up the implied chances on both sides of a market and you get more than 100%. That excess is the sportsbook’s margin — the vig, or juice. It is why a coin-flip market is priced at −110 on both sides rather than +100.
A straight bet on who wins. No margins, no handicaps — just the winner.
The favourite gives points and the underdog receives them. A −6.5 favourite must win by 7 or more for the bet to cash.
A bet on the combined score of both teams being above or below a posted number.
A bet on something specific within the game — a player’s statistics, the first scorer, whether there is overtime.
Several selections combined into one ticket. Odds multiply, but every leg must win.
A long-term bet on an outcome decided at the end of a season, such as a championship winner.
Betting is entertainment with a negative expected value built into the price. There is no system that changes that. What you can control is how you play.
In American odds, a minus number shows how much you must stake to win $100 and marks the favourite; a plus number shows the profit from a $100 stake and marks the underdog. In decimal odds, multiply your stake by the number for the total return including your stake.
The vig is the sportsbook’s built-in margin. It is why both sides of an even market are priced at −110 rather than +100 — you risk $110 to win $100, and the difference is the house’s edge.
A point spread handicaps the favourite by a number of points so that both sides of the bet are roughly equally likely. A −6.5 favourite must win by 7 or more; a +6.5 underdog can lose by 6 and still cash.
A push is a tie against the number — for example a −7 favourite winning by exactly 7. The bet is void and your stake is returned.
A common approach is a fixed unit of 1–2% of your total bankroll per wager. The right amount is whatever you are comfortable losing entirely.
No, and you should not plan to. The odds include a margin that makes betting negative expected value over time for the overwhelming majority of bettors. Treat it as paid entertainment.
Wagers on cancelled or postponed events are normally voided and stakes returned, subject to the timeframes in the betting rules.
You must be at least 18 years old to open an account and place a wager.
