Types of Casino Online Welcome Promotions
Casino sign-up bonuses come in various forms. Below, we’ll explore the different types of casino bonuses you’ll encounter at online casinos.
Matched Deposits
A matched deposit bonus is when a casino matches the amount you deposit by a certain percentage, generally capped at a maximum value. For example, in a 100% match deposit up to $3,000, you’ll receive $200 in bonus funds if you deposit $200. The maximum bonus you can receive is $3,000, even if you deposit more.
Free Spins
In this promotion, you are given a certain number of spins on a specific slot game. Free spins offers often form part of another promotion, such as a match deposit or a no deposit bonus.
This allows you to try the slots without risking much of your bankroll. You get to keep any real money payouts from the free spins.
No Deposit Bonuses
Online casino no deposit promotions reward players with bonus funds for free. However, they are normally of a low value and the terms can be rather stringent. The most common no deposit casino bonuses are free spins, credit for completing tasks, referral bonuses, or online casino birthday promotions.
Existing Customer Casino Promotions Online
Unlike welcome bonuses, existing customer promotions can be used multiple times. In the next section, we’ve outlined the types of online casino bonuses platforms use to thank you for your loyalty.
Reload Bonuses
Once you’ve used your casino sign-up bonus, you can unlock a reload bonus when you deposit funds into your account again. This type of casino bonus works similarly to match deposit bonuses. However, the percentage and amount offered are usually lower than those of casino welcome bonuses.
Happy Hour Free Spins
Happy Hour Free Spins are offered by some casinos as a perk for slot lovers. If you place a deposit at a specific time, you can earn a predetermined number of free spins on particular online slot machines.
VIP & Loyalty Casino Bonus Rewards
Loyalty schemes offer rewards, such as cash or additional benefits and perks, to keep you engaged. The general rule of VIP or loyalty programs is that the more you wager, the higher you move up the tier levels, leading to better payoffs and advantages.
Online Casino No Deposit Bonuses
The most popular kind of casino no deposit bonuses are those you get for introducing friends or performing simple tasks, such as verifying your email address. However, finding real money online casino no deposit bonus codes can be challenging. This especially holds true at credit card casinos that need to pay high processing fees.
As part of our guide, we’ve found the best online casino promotions that do not require a deposit at Wild Casino. This platform offers you three free entrance tickets daily to participate in its slots, blackjack, and roulette tournaments.
Referral Bonuses & Cashback
Referral bonuses and cashback provide additional perks, even if they are not the same as online casino no deposit bonuses. Such offers are available at Lucky Creek, Bovada, and Wild Casino.
With referral bonuses, you get an incentive when you recommend a friend who then opens an account and deposits funds. On the other hand, cashback offers give you a refund, which is usually a percentage of your net losses.
How to Claim an Online Casino Bonus in the US
To claim one of the best casino sign-up bonuses and start playing for real money, you need to register an account at the casino. Here’s a step-by-step guide using Wild Casino as an example. Many of the recommended gambling sites have a similar process.
Step 1: Visit the Casino’s Website
Open your web browser, go to Wild Casino’s main page, and click ‘Join Now.’ Fill in your details and click ‘Create Account’ when you’re ready. Sometimes, an online casino will ask for a promo code here, so be sure to enter one if we’ve provided it.
Step 2: Verify Your Email Address
Wild Casino will send you an automated welcome email, while some operators may send you a text. You’ll need to click a button to confirm your email address. This ensures you receive promotional materials, like new online casino no deposit bonus codes.
Step 3: Top Up Your Casino Account to Receive Your Casino Sign Up Bonus
To deposit funds, click ‘Cashier’ from the main menu. This will take you to the banking page, where you can see all available payment options along with their minimum and maximum limits. Select your deposit method, choose your bonus and enter a promo code we have provided if prompted, and follow the instructions to complete your payment.
Step 4: Play Real Money Online Games
Once the funds reach your account, usually instantly, you can start playing Wild Casino’s range of games. It’s a good idea to find games that contribute fully to the casino’s online promotions, like slots.
What Games Can You Use Online Casino Bonus Offers On?
Online casino offerings and bonuses generally have eligible games that qualify towards their wagering terms, which you’ll find in the T&Cs. To help you find one depending on the game you’ll be playing, we’ve gathered the best online casino promotions that you can use below.
Slots Casino Promotions
Slots are the best way to meet wagering requirements as they usually contribute 100%. Many offshore casinos offer bonuses specifically for slot enthusiasts, including match deposit bonuses, progressive jackpots, and free spins.
Blackjack Casino Promotions
Unlike slots, blackjack games do not contribute fully towards many match deposit bonuses’ rollover requirements. Tournaments, free table chips, and cashback are the most popular and best online casino promotions that you can find at the top online blackjack casinos. Everygame Casino has a dedicated tournament that you can join with a variety of rewards that a lucky winner could win.
Roulette Casino Bonuses
The best online casino promotions for roulette players are loyalty schemes, rebates, or cashback bonus offers. These are the most popular promos offered by the best roulette casinos in the US.
Because of its very low house edge, other top online casino bonuses for roulette are hard to find. Furthermore, they generally only offer a maximum rollover contribution of 5%.
Poker Casino Bonuses
Promotions for poker players can include free roll tickets or free entrance into poker games, similar to what you might find for blackjack. Gambling sites with dedicated poker platforms, such as Everygame and Bovada, also offer bonuses specifically for this platform. They also include tournaments that you can join to win high-value prizes.
Terms & Conditions for Online Casino Promotions
Reading the fine print of an online casino bonus is important as it outlines the wagering requirements, eligible games, and more. These elements work together and cannot be viewed independently.
If you do not follow these terms, you won’t be able to redeem or keep the reward. We’ve gathered a list of the main terminology here to help you become familiar with it.
Rollover Requirements
All online casino bonuses come with a wagering or rollover requirement. This represents the number of times you need to wager your bonus funds before you’ll be able to withdraw any winnings. For example, if the bonus is a 100% match with a 25x wagering requirement and you deposit $200, you must first wager $5,000 (25 x $200) to meet the requirement.
Time Limits
Along with the rollover requirement, the terms and conditions will specify an expiration period or time limit. This gives you the time frame in which you must fulfill your wagering terms. Casino sign-up bonuses usually have a 14 or 30-day expiration period, while promotions for existing customers generally have shorter ones.
Eligible Games
Although casinos feature thousands of games, they do not all contribute equally toward the wagering requirement. Slots are the best option as their contribution is 100%.
However, other games like table games and live-dealer games can have a low contribution rate or none at all. Other online casino bonuses, like free spins, tournaments, or ‘Games of the Week,’ are generally only valid with a pre-determined slot or slots by a particular slot developer.
Minimum Deposit & Win Limits
To qualify for an online casino promotion, you need to check the minimum deposit required and ensure you deposit this amount or more. Additionally, a match deposit bonus will specify the maximum amount it will give out. For instance, if a 100% match is capped at $2,000, even if you deposit $2,500, the casino will not provide any bonus money beyond $2,000.
Payment Method Restrictions
Another factor to look out for is the payment method that will activate the online casino bonus. Banking methods such as Skrill or Neteller are not generally accepted to trigger a bonus. On the other hand, crypto deposits can offer a higher-value reward and often require a lower minimum deposit.
Let’s take a look at the available payment methods and minimum deposits from some of our top online casino choices:
| Casino | Minimum Deposit | Available Payment Methods |
| Wild Casino | $20 ($75 to also get free spins) |
|
| Bovada | $10 |
|
| Lucky Creek | $20 |
|
| Black Lotus | $20 |
|
| Ignition | $10 |
|
| BetUS | $50 |
|
| Everygame | $20 |

Best Online Casino Promotions for Mobile
All of our recommended casinos rank among the best casino apps since their websites are mobile-friendly and fully responsive. While in most cases the bonuses are the same, some casinos offer promotions specifically for mobile users.
Top Tips for Using Casino Online Bonuses
To help you make the most out of your online casino promotion, we’ve listed five useful tips:
- Play slots – Slots are the best way to fulfill your rollover requirements as they contribute fully toward them. Other games, such as video poker and table games, generally have a significantly lower wagering contribution rate.
- Find slots with a high RTP – Although it’s not a guarantee, slots with a high Return to Player (RTP) give you an advantage. We invite you to read our guide about how to win at slots to learn other tips and strategies when playing this popular game.
- Choose bonuses with low wagering requirements – High rollover requirements mean you need to play more to meet them. Pick a bonus where you can afford to reach its requirements and gamble safely. Avoid higher-value bonuses if you cannot meet their wagering terms.
- Do not activate two bonuses at once – Many casinos will not count them as valid if you do.
- Practice responsible gambling – Walk away from your losses and take frequent breaks.
Conclusion
Wild Casino ranks as the number one casino with the best online promotions in the US. This online gambling site welcomes you with two separate bonuses, worth up to $5,000 for USD deposits or $9,000 for crypto users.
