Secret Casino Bonus

Can you keep a secret? Yes? Ok great, did you know that many online casinos partner with websites like Gamble-USA to provide secret casino bonus codes? It’s true!

Forget about the standard promos you see on casino websites – what you really want is exclusive promos that offer a little more value and are incredibly easy to obtain once you know what they are and how to get them.

In this guide, I explain the premise behind affiliate promos or secret bonus codes as they are sometimes known, how they work, and where you can use them.

Top US Online Casinos With Secret Bonus Codes

Not all legal US online casinos offer these secret codes but we work with a range of top-rated platforms to bring you exclusive welcome offers when you register a new account with the platform. You don’t need a secret code as such, but you can find either a unique sign-up link or a special promo code on our site for these online casinos:

What are Secret Casino Bonus Codes?

Ok, so I’ve given you a comprehensive list of casinos that have secret promo codes, but you might still be wondering what they are.

Secret casino bonuses are those not available directly on an online casino website or not immediately visible until you complete a certain action.

They are exclusive and are typically given to affiliate companies like us, or require you to have done something extra like make a set number of deposits, or signed up for an email newsletter.

Types of Secret Casino Bonuses

Most secret casino bonus codes are for new players, but there is some variance and I have listed the most common types below.

Affiliate codes or links

The list I created above was for affiliate codes and links. These are simple – the casino gives platforms like GUSA exclusive codes or links that are not available on their website. We share the links with you and everyone is a winner!

Email promotions

Some casinos have email newsletters you can sign up too and they will periodically send emails with casino updates and things like new game releases. However, they may sometimes give exclusive promos via their emails too.

Promo after X deposits

Some promos don’t trigger until you have made a set number of deposits or spent a set amount with a casino. For example, you might have to make 3 deposits, and for your 4th deposit, you then get a matched deposit bonus or free spins. To spice things up, the match rate value and bonus cap might be hidden or secret until you unlock it.

High roller or VIP promos

It’s relatively common for casinos to give additional perks and bonuses to VIP players or high rollers who are spending a huge bankroll compared to most general players like me or you. Typically, these secret bonuses are available on request only.

How to Use Secret Casino Bonus Codes

Secret bonus codes typically come as either a unique link that takes you to a modified sign-up page, or a promo code that you enter during the registration process. These are the typical steps you have to take:

  1. Click on the unique link or copy the exclusive promo code.
  2. Click on the sign-up, create a new account, or register button.
  3. Complete the registration form and enter the promo code if applicable.
  4. Verify your registration (typically done by clicking an email link).
  5. Make a deposit if the promo is a deposit bonus.
  6. Use your bonus cash and have fun!

To make sure that you do things properly, I advise always reading the terms and conditions fully beforehand so you know what to do and how to claim the offer, but in most instances, it’s done via the registration process.

Some offers may appear when you do certain actions and these are more difficult to describe. You just have to stay vigilant and look for notifications and check your emails regularly to see if any secret bonuses are activated.

Things to Watch Out For

These offers are fantastic, but there are things you need to be aware of and I can’t stress enough the importance of reading the terms and conditions fully for any promotion.

Wagering Requirements

Most cash bonuses have wagering requirements. This is a set multiplier you must spend before you can withdraw the bonus amount. For example, most secret no-deposit bonus codes have a 1x wagering requirement so if you got $20 in bonus funds, you would need to spend $20 before withdrawing it.

Legal US States

Promotions aren’t always the same for each state version of an online casino! For example, we have exclusive secret codes for Caesars Casino but they are different for New Jersey, Michigan, and Pennsylvania – PA and MI new players get a no-deposit bonus, whereas NJ players get free spins.

Tip: Since online casinos are not as widely accessible as we would like them to be, weโ€™ve also secured a sweepstakes casino secret bonus code to use in 48 states. Tap on Fortune Coins below and follow the verification steps to get $12 free play. Then, our exclusive link ensures that if you buy the $10 coin bundle, youโ€™ll get a MASSIVE 400% match! Thatโ€™s $62 for $10!

Expiry Periods

Oftentimes bonus cash or free spins also have an expiry period and you have to use them and meet any wagering requirements within a set period. For no deposit bonuses, it’s typically 3-7 days, but matched deposit bonuses usually give you longer up to 30 days or more. If you don’t spend the bonus within this period, it expires and is taken from your account.

Game Selection

Secret promos may limit which games you can use your bonus funds or free spins on too. Sometimes, particularly game categories are excluded from promos (usually the ones with the highest RTP!) and free spins may be tied to one specific video slot.

As you can see, these deposit bonus codes aren’t readily available and you typically can’t find them on online casino websites. So how do you get them and keep track of the latest exclusive offers? I love a good deal so have a range of methods and research options detailed below.

Bookmark GUSA

Gamble USA has a wealth of casino deal information for new players and we work with a wide range of legal US online casinos. Our team is continually researching the best promos for you and forging partnerships with the biggest brands in US iGaming.

The simplest thing you can do, therefore, is bookmark our website in your web browser favorites. This takes just a few clicks and you then have instant access to our site. You can then check our various bonus code guides and casino reviews to keep up to date with new secret promotions we have access to.

Contact the Customer Support Team

Sometimes it is possible to approach the online casino directly and speak to their customer support team. The best way to do this is via a live chat or telephone line as then you can speak to someone directly as opposed to waiting for an email reply.

There is certainly no harm in asking customer support if they have any other promotions not listed on their website – the worse they can say is no! And who knows, they could give you better promotions compared to the standard welcome offer for example.

Checkout Gambling Forums on Reddit

I will readily admit that I’ve spent hours trawling through Reddit and while it can be a black hole of nothingness, it also can yield results for casino research. There are sub Reddits and general online forums dedicated to online gambling and many of these discuss promo codes or post details of secret slots casino offers. I advise you to treat any info on Reddit with caution though and you may end up spending time on fruitless promo codes that have expired or don’t work.

Summary

Just because an online casino only shows a handful of promotions on its website, this doesn’t mean it’s the only bonuses you can get! Secret bonus codes are real and they are often better than the standard promo codes on display – you just have to know how to get them.

Our website is your best source for these deposit bonus codes and exclusive welcome offers so why not browse through our promo guides and casino reviews to see what you can find? The online casinos I listed above like BetMGM, Caesars Casino, and Borgata are a great starting point and all have exclusive promos.
