Casino Bonus Wagering Requirements

The most common limitation attached to casino bonus offers (especially welcome bonuses) is a wagering requirement. The wagering requirement, also called a rollover requirement or a playthrough requirement, dictates how many times you must wager your bonus funds. You can only withdraw your bonus wins after the requirements are met.


You get a new players online bonus of $100 from a casino that has a 30x rollover. Now you need to wager 30 x $100 = $3000 on real money games before cashing out.

This sounds like a large amount of money, but it’s less than you’d think. Since both winning and losing rounds, as well as playing with the winnings, counts towards the limit, betting $3000 is no big deal. It’s 3000 rounds of $1 slots spins for example. Those spins stack up in no time.

Wagering Requirements for different Casino Games

When you wager towards a rollover requirement, not all casino games are treated equally. Some online casino games contribute less than the full bet size towards the wagering requirement.

Each games wagering contribution towards playthrough requirements changes from casino to casino. Here are the contribution numbers from one US players accepting internet casino:

Game Contribution Percentage
Video Slots 100%
Progressive Jackpots 100%
Roulette 20%
Blackjack 20%
Other table games 20%
Video poker 20%
Scratch Cards 20%
Live Dealer Not allowed

Additionally, you may see contribution restrictions for selected slot games. At this casino couple of great NetEnt casino slots like Jack and the Beanstalk and Steam Tower only contribute 20% towards the wagering requirement. The casino may also impose a maximum bet on the wagering.

Best Games for Casino Bonuses

You need to consider three things before you choose how to use your sign-up bonus.

  1. Bonus Wagering Requirement
  2. Return to Player
  3. Available Bankroll

Table Games

Table games have high RTP (return-to-player) but do not really count towards wagering. Look out for bonuses with time limits, because you might need to grind day and night to actually claim bonus funds.

Online Slots

Online slots are the typical choice for casino players. They are fun, and light to play. The RTP is lower than table games, but they are a lot faster to play. You do run through your bankroll quicker.

Jackpot Slots

Jackpots are a type of online slot where the wins grow progressively, until someone hits the jackpot. If you want to use your bonus for life changing money, this is the game you play. Just check bonus terms and conditions, because some bonuses have a max payout cap. Often you need to use the max bet to win the jackpot.

Online Casino States

Currently, there are three states where you can legally gamble at online casinos, with one state at the verge of legalization.

  • New Jersey Online Casino
  • West Virginia Online Casino
  • PA Online Casino
  • Michigan Online Casinos

How to Choose the Best Legal US Casino Bonus?

Free Money No Deposit Bonus

Some casinos offer better bonuses than their competitors. Take your time and check all of them out. Choosing the best casino is easy with Bonusfinder.

  1. Decide on the amount that you’re willing to deposit and gamble with. Gamble Responsibly. Never play with money you can’t afford to lose. If you can’t lose any cash funds, take advantage of one of the free money bonuses.
  2. Based on what you’re going to deposit, select your bonus from the USA casino bonus list. We update our listing weekly with all the latest offers, and we only promote trustworthy, licensed casinos in the US.
  3. Either play slot machines or read the fine print. While it rarely matters to slot players, table game, live dealer, and video poker fans should check out the details: wagering requirements, wagering contribution, maximum bet amount, bonus expiration date and restricted games.
  4. You should educate yourself on the casino you choose. If you choose to play for example at 888 Casino, you should always read our 888 Casino review first. Reading our reviews is a sure-fire way of knowing the strengths and weaknesses of a casino.
  5. Now it’s time to play casino games. Sign up to a bonus casino from our green `PLAY WITH` button
  6. You should always check our reviews first to know who you’re getting involved with. For example, reading our Tropicana Online Casino review is a sure-fire way of knowing the strengths and weaknesses of a specific casino. And also important things like minimum deposit, deposit options, and the casino promo code.
  7. After winning real money, you need to meet the wagering requirements and then you can cash out.

Casino sites will often ask your personal details like age, social security number etc. when you create a casino account to ensure a safe gaming experience. They will also ask for credit cards for deposits and e-mail for sending you deposit casino bonus codes that can add bonus value to your casino gaming. However, legit online casinos will never ask your social media or other non-relevant details.

You can find the wagering requirement of the offer in the online casino’s Terms and Conditions, or just check our review of the casino. BonusFinder’s reviews are always the best source for choosing the best casino bonuses in the US.

Casino Bonuses Q&A

☑️ Are online casino bonuses worth it?

It depends what you are after. Casinos offer very generous casino promotions for new players and more often than not, you can gain some of the house edge back while using the bonuses. You also get more playing time on your favorite online casino games.

☑️ Can I really get free online casino money?

Yes, you can. For Americans, the free money offers are incredibly lucrative as the no-deposit bonuses come with very player-friendly terms & conditions. Some no deposit online casinos require only 1-10x playthrough on their free money offers. Advantage: American gambler.

See the top of this page and get the best free money offers in April your state on slots and live casino games like roulette and blackjack.

☑️ Can I play online casino games without a bonus?

Yes, you can. Casinos have different procedures for this, but in most cases contacting live chat and saying you don't want the bonus will do fine. People sometimes do this because they don't want to go through the playthrough requirements.

☑️ Do live casino players get bonuses?

Yes, they do. In some cases, you can use exactly the same welcome package as you'd get for slots, but not all online casino games are created equal to count towards the play-through requirements.

While slots contribution is almost always 100% towards the wagering requirements, in a live casino you're lucky to get a 20% contribution per bet. But you can get quality deposit bonuses and play live casino, it just takes a bit more time to play through the wagering requirements. For this reason, many live casino players simply decline the bonus and only play with real money, with no strings attached.

For more about live casino bonuses, see our full live casino bonus list where you may run into some rare live casino bonuses.

☑️ Does my banking choice matter when getting a casino bonuses?

It can matter. You don't have to worry if you're using, for example, a credit card, Pay by PayPal Casino or eChecks to deposit, but with e-wallets, you need to be careful. Many online casinos have excluded Neteller and Skrill as a deposit method from the bonuses, as the e-wallets charge too much for transactions. Some casinos also don't carry all deposit options.

☑️ Are casino bonuses available at mobile casino?

Yes, casino bonuses are available at mobile casinos. You can claim your bonus whether you're on the go with your iPhone or at home in your pj's preparing for football Sunday. You can get the casino and sportsbook bonuses easily through your mobile phone.

☑️ How quickly are the bonuses credited to my account?

Instantly. Just like your deposits, you'll see your extra cash added right on your account right after you've deposited.

If there's a lag, hold on for 2 minutes. If you're still not seeing the bonus money on your account, contact the casino's customer service, and they'll sort it for you.
