The Best Sportsbook Bonuses For 18 And Over Players

A sportsbook promo usually awards members with bonus cash that is a percentage of the deposit. For example, a member can accept a sportsbook bonus that matches 75% on a $1,000 deposit up to $750. The bonus cash can be adjusted based on the total transaction, as long as the minimum is exceeded.

There are often terms that members need to complete to earn the right to withdraw the money. This always involves betting the money in the sportsbook a certain number of times and can be referred to as rollover or playthrough. Cryptocurrency deposits with Bitcoin are often eligible for larger bonus cash awards.

Gamblers can keep track of their payback conditions for any sportsbook bonus cash in their account. These bonuses can be accepted by entering a sportsbook promo code that can be found on their website, or by selecting the promo in the deposit window.

Common Types Of Sportsbook Promo Codes

Sports Betting Welcome Bonuses

Attracting new customers is a big deal to 18 and over sportsbooks, which is why they offer the largest cash bonuses to members signing up for the first time. Every online sportsbook that we recommend offers a sports betting signup bonus, and many of them can be repeated for follow-up deposits.

Cryptocurrency Sportsbook Bonuses

When you use Bitcoin or other cryptocurrencies to deposit into your sportsbook account, there are often bonuses available that include larger cash promos than when using USD. This is because 18+ sports betting sites prefer crypto over all other banking options and encourage its use with large promo cash offers.

Sportsbook Reload Bonuses For Future Deposits

While not as common as welcome promos, re-up bonuses are often offered at eighteen-friendly sports betting sites. These bonuses usually award less than what the signup promo promises, but the repayment terms are also typically easier to complete. The type of payment you use can also dictate the terms of the bonus in some cases.

Sportsbook Referral Bonuses

Refer-a-friend bonuses are offered at most over 18 sportsbooks that can earn you promo cash every time someone you know signs up for an account and deposits money. These offers are usually unlimited and can be claimed as often as you like. Most books allow players to create a code that can be sent to associates so they can complete the account creation process. As soon as money hits their account, bonus cash is added to yours.

Exclusive Membership Bonuses

Some online sportsbooks allow members to become either VIP level or rewards members by opting in on the program, or through automatic enrolling upon account activation. As players collect rewards points through their regular gambling activity, they rise to new levels where unique bonus cash offers, and other incentives are made available.

How To Claim A Sportsbook Bonus

18 Plus AcceptedTaking part in an online sportsbook bonus cash offer requires 18 and older members to do one of two things, either enter a promo code or select the bonus from a dropdown menu when making a deposit.

Sportsbook promo codes can be found on a promo page at each online sportsbook. This page can be accessed either by clicking a promo button in the overhead menu or via a dropdown menu. Here is where you’ll find the spelled-out terms and conditions of completion.

You can control the amount of their bonus depending on how much you deposit, as long as it is above the minimum requirement. The bonus cash will be added to accounts at the same time the deposit transaction completes.

How To Complete The Terms Of A Sportsbook Promo

When looking through the conditions of paying back sports betting promos, you’ll notice rollover or playthrough terms. For example, a 25X rollover requirement may be attached to a bonus that needs to be completed before requesting a withdrawal.

In this case, the 25X playthrough requires you to wager the bonus money in the sportsbook 25 times through. This process can be tracked in your account profile where promo cash and withdrawable dollars are contained in separate accounts.

Some books include conditions where certain types of wagers are repaid at differing percentages, so be aware of that before accepting a bonus. If the terms seem too difficult to complete, you can consider making a smaller deposit and accepting less promo cash. Smaller bonuses take less time to fulfill.

Rewards Programs And VIP Memberships

Many of our favorite 18+ sportsbooks feature rewards programs where members can collect points each time they place a bet. These points accumulate based on your betting activity and how much you spend. The accumulation ratios differ at each site. Some sportsbooks ask you to sign up while others enroll new players automatically.

Bovada Rewards – Any member of Bovada can opt into their rewards program by signing up for it at their website. Points can be earned every time you place a bet on sports. These points can be traded in for bonus cash once you have enough to trade in for at least $1. Parlays, teasers, and round robin bets award at higher values than singles. As point thresholds are crossed, members start earning more perks per wager as they enter higher Rewards tiers. Moving up the tier ladder also lets members cash in points for dollars earlier.

BetUS Loyalty Program – Just by creating an account at BetUS, members are automatically registered to take part in their rewards program. When you make bets at BetUS, rewards points are added to your account. The further along you advance in the loyalty program, more perks will be unlocked. These extras include cost-free payouts, larger sportsbook bonus offers, $500 in free play money when you cross each rewards tier, a custom toll-free number for VIP members, and occasional invites to exclusive casino tournaments.

BookMaker EU – The BookMaker rewards program operates similarly to others in that points are collected based on betting activity that can be used to exchange for bonus cash. There is no signup required because points begin collecting as soon as you create a BookMakerEU account. Free play bets, moneyline wagers, and live casino games do not count toward the collection of points. Members can redeem their BetPoints by clicking the Promotions tab and selecting “Use my BetPoints.”

BetOnline VIP Rewards – Members begin at the VIP Rewards level of Bronze and can move up 14 levels to Black III by betting on sports and collecting points. As you cross into new levels, new benefits are unlocked such as weekly cash boosts, priority withdrawals, a reduction of any applicable deposit fees, higher bet limits, and exclusive bonuses. Once you cross the million-dollar threshold, you become a diamond member which grants you access to a dedicated VIP team to assist you with any needs.

Cryptocurrency Memberships

Bitcoin coinBovada Premium Crypto-Exclusive Membership – Cryptocurrency depositors at BovadaLV can become a Crypto-Exclusive member by signing up for the promotion. By taking part, players gain access to a weekly 50% match bonus that can add up to $200 to your account. Bovada currently accepts Bitcoin, Ethereum, Tether, Litecoin, Bitcoin SV, Ethereum sportsbook deposits, and Bitcoin Cash sportsbook deposits.

Reduced Juice Sportsbooks

BookMaker EU – For certain sports betting markets, BookMaker EU will offer reduced juice so that you can take home more cash each time you place a winning wager. For instance, juice on a given bet is typically set at -110, but reduced juice at BM can drop to -108 if the odds are included in the promotion. That means you’ll get more money per winning a wager than usual because they are taking a smaller cut off the top. BM will highlight these reduced juice betting lines in their sportsbook, and they will be made available to all account holders.

BetOnline – For the entire 2024 NHL Stanley Cup Playoffs, BetOnline is offering reduced juice on select games that can be wagered on by any active member. This applies to NHL over/under betting and moneyline odds for game winners. Vigor rates as low as -106 can be exploited that place more money into your pocket per each winning Stanley Cup bet than other popular NHL sportsbooks. This is an offer you don’t want to miss if you plan on betting on the NHL Playoffs.

18+ Sportsbook Bonus FAQs

FAQ'sWhere Can I Find Sportsbook Promo Codes?

There is a sports betting promo page at each of the 18-friendly sites we recommend that spells out the terms of the bonus and lists the code to enter if applicable. Some sportsbook deposit bonuses can be activated in the checkout window and do not require a promo code.

Are These Bonus Cash Sports Betting Offers Legit?

Yes, but we can only vouch for the ones offered at the 18+ sports betting sites we recommend. You need to become familiar with the terms of completion for sportsbooks promos which are supplied on their respective websites. Complete the terms and withdraw the cash. It is that simple.

What Is The Best Signup Bonus Sports Betting Sites Offer?

The best sports betting promos are in the eye of the beholder. The best sportsbook bonus is unique to you and should be entirely dependent on whether the terms can be completed before the deadline. To some, the best sportsbook signup bonus may be the one offering the most cash. If that describes you, just pick the one offering the highest dollar amount and largest matching percentage. To others, the offer with the most favorable wagering requirements is the best bonus, which in this case would be Bovada.  Their bonus is not always the highest dollar amount, but their rollover terms are the most generous.

Are There Any Sports Betting Apps Promos?

We’ve occasionally seen sports betting app promos but they are not common. The reason is that the sites we recommend port their mobile sportsbooks over the web using browser apps like Chrome and Safari – the the bonus offers remain the same regardless of what device you’re using.

Are Sportsbook Bonuses Taxable?

Not exactly. While the federal government and some US states impose a tax on all income, gambling earnings included, a sportsbook bonus does not necessarily become a tax burden, however, the winnings associated with a bonus can qualify for tax reporting. No taxes need to be reported unless real cash has been won and withdrawn based on bets made with bonus cash.

Are There Bitcoin Sportsbook Deposit Bonuses?

Yes, many sportsbooks offer either Bitcoin bonuses or promos that can be activated using any of their supported cryptocurrencies. BTC is often preferable to online sportsbooks over traditional options such as credit and debit cards, so Bitcoin bonuses are not uncommon and often award higher totals. Bovada takes it a step further and offers a Bitcoin exclusive membership with even more enhanced promotions and additional perks.

What About Sportsbook Super Bowl Promos?

Betting on NFL games is a big attraction at online 18 and over sportsbooks, and there are often promotional offers made available at the beginning of each season. There are also several promos for betting on the Super Bowl each February as well as contests that deliver heaps of bonus cash.
