Bonus Details

BetOnline is one of the longest-running sportsbooks on the market. This experience means this bookie knows what its players want from their sports betting promos.

When you sign up at BetOnline you’ll get 50% of your first deposit back up to a maximum of $250. This means that if you make a first deposit of $500, you’ll unlock the full $250 sports betting bonus and take your opening bankroll up to $750.

While this isn’t as generous as some of the other offers, the BetOnline promo has a huge advantage: there’s no rollover, meaning your bonus bets are paid out instantly in cash.

There are a few restrictions on using your free betting bonus, but they’re nothing to worry about. Most markets only allow you to use your bonus balance on single legs with max odds of +150, but as all winning free bets are paid out in cash these are the kinds of bets you’ll want to target anyway.

Pros

  • No rollover for your bonus
  • Huge choice of banking options
  • High betting limits
  • VIP Rewards program

Cons

  • Limits on how free bets can be used
  • Low total bonus amount

Sportsbook Bonuses Explained

All of the best sports betting sites will offer you sportsbook promos and bonuses to boost your account balance. But as you may have guessed, different sites will have different sports betting promos, with each one having its own particular strengths – more on that later.

First, let’s see how the best sports betting bonuses work.

What are Sportsbook Promos?

Sportsbook promos are bonuses and rewards that a sportsbook will give you to help boost your account balance. The biggest bonus you can expect to receive is when you sign up for a new account, where you can get additional credit on your first deposit as a sports betting bonus.

Remember that you can join as many sportsbooks as you want to grab all those bonuses but can only have one account per site.

There are also plenty of sports betting promotions available once you’re signed up and playing. These can be reload bonuses, where you get a boost when you add more money to your account, along with free bets and even free slots spins if the site also has a casino.

What are Sportsbook Promo Codes?

When you join new betting sites, you may need to enter a special promo code to unlock your welcome bonus. You’ll be prompted to do this when you register for an account, and don’t need to worry about missing out as the codes are readily available.

Sometimes you don’t need a code to unlock your sports betting bonus, and you’ll get it just for signing up and making a qualifying deposit. You’re not getting any less of a sportsbook bonus when you don’t need to use a code, some sites simply don’t require it.

Sportsbook Promos Terms and Conditions

Each sportsbook will have its own terms and conditions for receiving a betting bonus when you sign up, and you should always make sure to understand them before signing up.

The one you really need to pay close attention to, though, is the sportsbook bonus rollover.

Sportsbook bonus rollover

Once you’ve figured out if the rollover is something you can manage, take a little time to check out the following terms.

  • Minimum Deposit – There will be a minimum first deposit you’ll need to make in order to activate your sports betting bonus after you sign up. This amount is usually slightly higher than the minimum deposit that the site accepts, so make sure your first deposit is enough to trigger your bonus.
  • Promotion Window – No sportsbook bonus will last forever. You will have a window to activate a bonus and to complete your rollover requirements. This is typically either 14 or 30 days. It’s also worth keeping in mind that only bets settled in this window count towards a rollover, so it’s not a good idea to use bonus funds to place futures.
  • Minimum Odds – Some sportsbooks will set minimum odds for markets that you can use your bonus on. These are still highly competitive, typically around -150, but will stop you from reaching your rollover by only backing heavy favorites.
  • Maximum Win – Some sites will have a maximum amount that you can win while using sports betting bonus. The limit is usually quite high, though, so this typically only affects very high stakes players.

Types of Sportsbook Promos

There are a few different kinds of sports betting promos that you can expect to see when signing up at a new sportsbook. Here are some of the most common.

Deposit Bonus

The most common sportsbook promo you’ll come across is a deposit bonus. These bonuses give you a percentage of your first deposit as free play credits.

For example, if you deposited $100 with a 100% deposit bonus, your starting balance would be $200. Remember, you’ll need to hit any rollover requirements before these bonus funds are paid out in cash.

Repeat Deposit Bonus

These are exactly the same as above, except you can use them on multiple deposits. This could see your second or even third deposit also snag you a nice big sportsbook bonus.

Reload Bonus

Some sportsbooks offer a reload bonus that you can use on future deposits. These work exactly the same as a deposit bonus, although offer a smaller amount. Typically, a reload bonus will give you around a 25% boost.

Crypto Bonus

Cryptocurrencies are rapidly becoming the preferred deposit method for some sportsbooks. You can often find special sports betting bonuses for using crypto. With these, you’ll get a deposit bonus of around 20% when you use crypto to deposit funds into your account.

Free Bets

One of the best sports betting promotions — a free bet is exactly what it sounds like. You’ll be given a credit to put on an event, and if it hits then you get the winnings. If it misses, then there’s no damage to your bankroll.

Reduced Juice

The “juice” at a sportsbook to the commission that is built into the odds you get. When betting sites promotions include ‘Reduced Juice’, it means that you are getting better odds because the sportsbook is lowering or skipping out on its commission.

Odds Boosts

When a sportsbook offers Odds Boosts, it means it has improved the odds to way above the normal market level. For example, a bet might normally have odds of +200, but with an odds boost applied the sportsbook improves it to +300.

These kinds of betting promos are heavily promoted if they are available, so it’s very unlikely that you’ll miss any odds boost offers.

Risk-Free Bets

With a risk-free bet, you’ll get your stake returned to you as a free betting credit if your cash bet loses. Sometimes the bonus credit will be subject to a rollover, but even if it is, these are still some of the best sportsbook bonuses for allowing you to stay in the game if one of your wagers misses.

Parlay Insurance

A parlay is a kind of bet where you combine multiple wagers into a single bet for massively improved odds. In order for the bet to win, all the legs have to hit. With Parlay Insurance, you’ll get your stake returned – usually as a free betting credit, but sometimes as cash – if you miss with just one of your legs.

How to Choose the Best Sportsbook Promos

There are a few things to keep in mind that can help you find the best sports betting promotions.

One-Off or Repeating Bonus

One of the biggest things to consider when picking the best sportsbook bonus for you is whether the bonus comes all at once with the first deposit or is spread out between the first several.

For example, if you were looking to place a lot of wagers in a short amount of time, like during March Madness or the World Series, then having the bonus all at once would be best. If you wanted to play more long term, for instance throughout the NFL regular season, then it may be better to take a bonus that is released gradually.

Do You Want a Casino Bonus Too?

Some sportsbooks also offer casino bonuses alongside sports betting. If you enjoy casino play then these may be worth considering, but if you’re a pure sports bettor then make sure that you can use all of your bonus on the sportsbook.

Rollover is Crucial

Generally speaking, the bigger sports betting promos have bigger rollovers, which mean you have to place more bets in order to meet the bonus requirements.

If you are a frequent bettor then this shouldn’t be an issue, but if you tend to place fewer wagers then think about if it’s better to take a smaller bonus with a lower, or no, rollover requirement in order to maximize your chances of hitting it.

Make Sure You Can Back Your Favorites

Check that the markets you want to use your sportsbook bonus on are available. All the sportsbooks here carry major national and international sports, but if you enjoy betting on a particular market then make sure it’s on offer. No bonus is worth missing out on backing your favorite team.

Check Out the Ongoing Sportsbook Promotions

Although the biggest sports betting promo you’ll get is the one when you open your new account, there are also regular sportsbooks promos for existing customers. As we mentioned above, these can range from reload bonuses, to bonuses awarded for making future deposits in crypto. It’s worth keeping an eye on these, as they can reward you in the long run.

Sports Betting Promo Payouts

There are a few ways you can withdraw your winnings from your sportsbook account.

Returning your money directly onto a debit or credit card is rare outside of state-licensed operators, and so there are plenty of alternatives to pick from at offshore sportsbooks.

Some of the most common are money orders, wire transfers and cashier checks, along with using services such as Person to Person.

By far the best and most popular option, though, is crypto. All the sportsbooks featured here allow you to deposit and withdraw funds in major cryptocurrencies, such as Bitcoin, Ethereum, Litecoin, Solana, Tether, and more. In fact, this is the preferred banking option for the fastest payout sportsbooks and instant withdrawal online casinos.

Sports Betting Promo Red Flags & Mistakes to Avoid

We all ignore Ts and Cs and inevitably make the odd mistake here and there. But when it comes to sports betting promos, you really don’t have to. Just follow these tips.

Watch the Rollover

Watch out for sportsbooks that have a high rollover before your bonus is paid out in cash, or that require you to rollover both your deposit and bonus. These restrictions can make it hard to hit your rollover requirement.

Check the Eligibility Window

It can take time to use the best sportsbook promotions, so make sure the offer you are considering gives you enough to take full advantage of it.

It’s also worth thinking about the timing of when you open an account. For example, if you enjoy betting on league soccer, a 14-day expiry window can make hitting a rollover tough if there is an international break in the middle of it.

Look Out for Bet Limits

Some sportsbooks put limits on the odds you can bet on with your bonus. While these typically are still generous and around -200, it’s something to keep in mind, especially if your preferred markets carry low odds.

Research Customer Service

One of the most important things is to review the customer service offered by your sportsbook. Sometimes issues can arise no matter where you bet, so it is important that you know that any problems will be dealt with quickly and fairly.

Best Sportsbook Promos Recap

You can get the very best sports betting promotions when you open an account with a new online sportsbook. Many sportsbooks offer huge deposit bonuses along with other perks such as free bets and odds boosts.

All sportsbooks offer these promos, so make sure that you pick both a site and an offer that’s best for you and how you enjoy playing. Check that the markets you want to bet on are available, look at what extra bonuses are available once you’ve used your welcome offer, and enjoy the action.

If you’re looking for a trusted site with straightforward sportsbook promos and no rollover requirements, BetOnline is the perfect place to start. Remember, you can sign up with as many different sportsbooks as you like to get as much free credit as possible.
