What is a Betslip?: How to Fill in a Betting Slip

Betting can be the perfect way to ramp up the thrill you experience when watching sports unfold. However, filling in a betslip can be daunting for newcomers, and any mistakes could cost you money.
This guide will explain exactly how to fill in a betting slip like a seasoned pro.
What is a Betslip?
A betslip is the ticket or coupon on which you build your wager before placing it. You and your sportsbook use this betting slip to record and track sports wagers.
The betslip is part online shopping cart and part payout calculator: You fill it out with what you'd like to purchase, and it shows you what you get in return for the associated cost. In this case, you're paying for potentially higher winnings and the entertainment value of seeing if your predictions are right.
You can place multiple wagers in each betslip or submit multiple betslips—whatever you prefer. Online sportsbooks build their terms of use into the bet builder so you can feel secure knowing you're sticking within the book's parameters, like selecting the correct number of parlay legs.
Components of a Betslip: What Goes on a Betting Slip?
While the display will differ slightly based on which sportsbook you choose and the bet you place, the core elements of your betslip will look the same as you build your bet:
- Market: The outcome you are wagering on.
- Odds: The odds associated with that outcome happening.
- Stake: The amount of money you're betting on that outcome happening at those odds.
Based on these three factors, most betting apps will automatically calculate the total cost and payout if you win your bet.
How to Read Odds on a Betslip
Online betting platforms sometimes let you change the odds format displayed throughout your screen, though most U.S. sites default to American odds.
If the odds are positive, they represent the less likely outcome. The number associated tells you how much you would win on a $100 bet.
If the odds are negative, they represent the more likely outcome. The number associated tells you how much you'd have to wager to net $100 with a win.
It's important to remember that odds are dynamic; they change. When you submit your bet, you lock in the price as it is now, unless otherwise stated on the betslip.
Where to Find your Betslip
When you select a market to bet on, it will be automatically added to your betslip, which will stay active on your screen until you decide to submit it. That makes it easy to keep track of your betslip and the wagers within it.
Once you've submitted your betslip, you can find your pending and settled bets in your player account.
How to Fill Out an Online Sports Betslip
Placing a sports bet online is far easier than in person. It is a simple, efficient process, and you will quickly understand it, as the best sites are extremely intuitive and user-friendly.
- You simply search for the match or tournament you are interested in.
- You will be presented with a wide range of betting options laid out in a neat, easily accessible format. A physical coupon in-store will only offer a limited number of markets, whereas you can often find hundreds of intriguing bets on a single match at leading online bookmakers.
- You simply click on a bet that appeals to you, and a betting slip to the right of the screen automatically opens.
- You can enter the amount of money you wish to wager in a box next to your selection, and it will tell you how much profit you stand to earn.
- You can add as many bets as you like to the slip and remove any you are unhappy with before clicking “Place Bet.”
- The system will then give you a receipt and tell you your potential return.
How to Place Different Types of Bets within a Betslip
You can place moneyline bets, point spreads, over/unders, prop bets, and futures within your betslip, either as a standard single bet or as a parlay.
Betslips look and function relatively similarly across different bet types, but there are some important distinctions that you should consider.
Standard Bets
Search for a sporting event that interests you, find a bet that appeals to you, and tap on it. That selection will be added to the betting slip that appears to the right of the screen.
It’s as simple as that.

Online Parlays
For a parlay, find another bet you like the look of, tap on it, and it will appear underneath your initial selection. Keep doing this as many times as you like.
At the bottom of your slip, there will be the option for a parlay bet. If you have chosen five selections, it will read “Five-leg Parlay,” “5 Fold,” or something similar.
You add your stake in a white box in that section of the betting slip and then click “Place Bet.”
You will be given a receipt showing the payout you will receive if all your selections are correct.

Round Robins & Teasers
Round robins and teasers take parlays to the next level. A round robin bet is essentially a parlay made of parlays: You combine multiple parlays into a single betslip. Teasers are parlays made up solely of point spread wagers, where you can pay to adjust the lines in your favor. The trade-off usually involves some of your winnings being taken off the top.
When building your bet, you'll see a tab marked "Round Robin" or "Teaser" to adapt your parlay. You can enter different stake amounts for each parlay, and your potential payout will be calculated automatically.

Betslip Enhancements
Depending on the sportsbook, some extra features might be available within your betslip that allow you to alter or enhance your wagers.
Fixed Odds vs. Changing Odds
You can submit your betting slip at the current fixed odds or enable dynamic odds pricing, in which your potential winnings change as the odds change. Sporting event odds are not static; they change as the circumstances change before and during the event itself.
Parlay Builders
Most betting platforms have unique parlay builders available within betting menus. When selecting parlay legs, your bet builder will automatically start forming. All you need to do is agree to bet, and your betslip will be locked in.
Flexible Parlays
Some platforms allow you for flexible parlays in which not every leg needs to win. You'll be shown the payout scale based on the percentage of your parlay you get right.
Within the betslip, you can select the number of legs that need to hit within your parlay to collect some payout.
Bonus Bets
Many platforms' betslips will store your available bonus bets and allow you to add them to your bet before submitting. It acts like a discount coupon when checking out at an online retailer.
