Types of Online Betting Bonuses

  • Deposit bonus
  • Free money
  • Free bets
  • Risk free bets
  • Profit boosts
  • Promotions and contests

You’ll always get an sports betting bonus when you sign up at an online bookie where you’re not a customer yet. Betting bonuses come in different forms, with most of the real value in deposits bonuses.

Most of the time, they’ll give you a sign-up bonus, so whenever you sign up at online sports books, they’ll credit you with the promised bonus when you register as a new customer. The best online bookies like Unibet also offer you free bets and risk-free bets for significant events like the Super Bowl or World Series.

What are deposit bonuses?

Deposit bonus at an online bookie always matches your deposit with a pre-set percentage. If they’ve got a deposit bonus and will “match it 100% up to $100”, like at Action247 it means when you deposit a hundred bucks, you’ll get $200 in total to your betting account.

Deposit bonuses are typically the most value out of any US online betting bonuses.

Free money

No Deposit free money offers are hard to come by in online betting. Some sportsbooks, like Barstool Sportsbook, offer bettors no deposit free money. The best no deposit free money offers are around $25.

If you’re lucky, you may find a $5 free money without a need to deposit, but don’t count on it. Always be ready to make a small deposit to make the best of an online bookmaker’s welcome bonus offers.

What are free bets?

Free bets are bets that a bookie gives either on sign-up or when you’ve been their customer for some time. Typically an online bookie matches your wager with a free bet of the same size.

What are risk free bets?

You can find more information risk free bets on our free bets info page.

What are profit boosts?

Profit boosts give extra to your wins. If a bookie gives you a “100% profit boost up to $100”, they’ll match your win up to $100. So if you’d like to bet $100 to win $190, you’ll get the $90 doubled if your side wins. Profit boosts are available for most sports leagues.

As free bets and risk-free bets, profit boosts are also usually given to either a new customer or an existing customer when a big event like the national championship or Kentucky Derby is coming up.

You’ll find out all the best offers for US players from BonusFinder. We’ll let you know if there is a promo code needed.

no vig nfl betting

DraftKings ran a no-vig NFL promotion for Week 1 of the 2019 season. Bettors in New Jersey and Pennsylvania got +100 odds on both sides, instead of the regular -110.

Promotions and contests for existing customers

A bookmaker will get you something extra, even though you might have used all the welcome offers. In addition to monthly promotions, the added value can range from event promotions to contests. UFC or golf bettors can be the lucky ones that receive the added value when big events are coming up and bookies are looking through accounts for betting activity on the sport in question.

Wagering requirements

Every type of real money betting bonus comes with some strings attached. In the online gambling world, these strings are called wagering requirements (also referred to as play through and rollover requirements).

You can’t withdraw your winnings before you’ve met the playthrough requirements. This means that you have to play through your original deposit and the bonus a set number of times. So if you deposit $50 for a $50 bonus, with a wagering requirement of 3, you need to bet $50 + $50 = $100 x3. Therefore, you need to bet a total of $300 before you can withdraw your bonus money.

For betting, the rollover requirement is usually 3 to 6. Compare this 3-6 to online casino bonuses, which have a rollover requirement of 25 to 60. It’s a huge difference.

Live / In-play Betting

Live betting is one of the most popular ways of online betting. You don’t bet just the pre-match card anymore. You can place wagers mid-game on intermissions and halftimes.

Live betting is the #1 way to make money in betting, as Las Vegas does have the pre-match number pretty well down these days. Live betting is still much less of an exact science for real money online bookies, as live betting has only been around for years, while the pre-match market has been around for decades.

In live betting, it’s much easier to judge the teams against each other as you’ve seen them play today on the same field or the court. The tempo of the game, defense stacking against each offense, and the way superstars play each other. You can see all this happen live and then decide on what you’re going to bet, instead of trying to beat the online bookie in pre-match betting.

Mobile Betting Apps

mobile betting app usa

The DraftKings sportsbook app is clean, straightforward, and fun to use.

Newsflash: You don’t need real money sports betting app to place sports wagers on your phone. All the online betting sites are entirely compatible with your phone’s browser, no matter if you’re running an iOS, Android, Blackberry, or a Windows Phone.

Real money betting apps are never necessary, as online bookies work very well using your browser. Google Chrome, Firefox, Safari – no problem.

However, you can find betting apps if your state has legalized online gambling. For example, in New Jersey, FanDuel and DraftKings have their real money betting apps in Apple’s App Store and Google Play Store. But you don’t need them really, as the mobile betting bookies work just as well on your browser.

Currently, you can’t download a betting app if you’re a resident of a state that hasn’t yet allowed online gambling. What would be the point, as you can’t gamble online again anyway? Once states legalize online betting, you’ll see online betting apps appear in your app store as well.

Best sports betting sites in the US

Currently in February 2021, DraftKings Sportsbook gets the nod. DraftKings started as a fantasy sports site, but they have taken the lead in the US as the most prominent sports betting site. As online sports betting is becoming legal state by state, DraftKings’ foray into the betting world has been a successful one.

You can bet all the major sports online. You can also bet on college sports, as well as English Premier League and the Champions league if you’re into soccer. The odds are competitive, and they know what makes US bettors tick: Great bonuses with ongoing promotions that you’ll benefit from in the long run.

These offers are currently available legally for gamblers in New Jersey, Tennessee, Pennsylvania, Indiana, New Hampshire, Iowa, West Virginia, and Colorado. They are likely expanding to the rest of the country when other states open up with legal betting options.

Always remember that when betting, you should enjoy yourself. Betting, and gambling, are for entertainment purposes only. When the fun stops, you should stop, too.
