What makes a casino bonus rare?

A casino bonus is considered rare when it offers unique benefits that aren’t normally on offer.

Examples include promos with exceptionally high match percentages, low wagering requirements, exclusive access to VIP players, or special promotions tied to limited-time events. No-deposit bonuses also tend to fall into the rare category.

Overall, these bonuses stand out by offering greater value or unique rewards that go beyond standard offers.

As the name suggests, these rare bonuses are hardly ever available, and finding them is akin to catching a needle in a haystack.

However, it’s not 100% impossible if you know where to look…

How to find rare casino bonuses

Rare bonuses appear once in a blue moon. So, to take advantage of them, you need to know where to look.

Here are the five best strategies for finding extra valuable casino bonuses.

1. Bonus websites

If you want a one-stop shop, dedicated bonus aggregator websites, like casinobonusdeals.io ( site for 🇳🇱 players ), specialise in curating the latest and most exclusive casino offers.

👉 These platforms regularly update their listings, often featuring rare bonuses not found on casino sites. How? Well, they often have experts who trawl for the latest bonuses and some even work directly with casino brands to ensure fresh news.

When you keep an eye on these sites, you gain access to limited-time deals, hidden promotions, and exclusive codes that can significantly enhance your bankroll.

Bookmark and monitor your favourites to stay ahead. Or begin now with the latest bonuses and promotions on Roger.

2. Reviews & forums

Next up: reviews, forums, and online casino communities.

🤓 These player-led spaces are goldmines for discovering rare bonuses. Fellow players often share insider information, invite-only codes, or promotional links that aren’t advertised publicly.

Following, or even better, engaging in these discussions, allows you to learn from experienced gamblers and uncover deals through word of mouth.

3. Casino newsletters

Did you know some casinos have newsletters?

📫 Even if you usually dislike email marketing, signing up for casino newsletters is a smart way to get early access to exclusive or rare bonus offers.

Casinos often reward loyal players with special promotions via email that aren’t available to the general public. These may include:

• Free spins
• No-deposit bonuses
• Cashback deals
• Extra loyalty rewards

Stay subscribed and check your inbox regularly so you don’t miss out on time-sensitive or high-value promotions tailored just for you.

4. Seasonal promotions

As mentioned in the strategy above, some bonuses are time-sensitive—and very easy to miss.

🎅 Many casinos launch special bonuses during holidays or major events, such as Christmas, New Year's, or major sports tournaments.

These limited-time offers often feature unique perks such as boosted match bonuses, themed free spins, or prize draws. Lots of juicy prizes for those on the ball.

Since most releases follow big calendar events, you should check the promotions page near public holidays or during tournaments. This way, you’ll be more likely to snag the funds.

5. New casinos

Lastly, don’t discount the newbies!

New online casinos often offer generous bonuses to attract players and build their reputation. These introductory offers may include no-deposit bonuses, low-wagering free spins, or oversized welcome packages.

🥇 Regularly scouting new casino launches gives you a first-mover advantage to grab rare deals before they become widely known or change.

But get them while they’re hot. These are usually limited-time deals, and the casino bosses revoke them once the website has enough players.

You should also ensure the new casinos are safe and legitimate, which brings us to the casino bonus red flags.

Casino bonus red flags

Don’t get caught up in finding the best deal at any cost. Sometimes, bonuses come with red flags that signal unsafe or scam offers.

A major warning sign is the absence of a valid gambling license from reputable authorities, such as the UKGC or MGA. Technically, Brits can use offshore sites, but these tend to have dodgy payment methods and lack player support.

You should also look for clear T&Cs. Vague or hidden terms, especially those related to wagering requirements, can be intentionally misleading. You redeem the funds and don’t realise you have to wager them 50 times until it’s too late.

🚨 Just remember that bonuses that seem too good to be true often are.

The takeaway

Finding rare bonuses takes a little more effort than using regular ones, but it’s worth it when you have extra funds in your account.

However, make sure you bonus hunt responsibly and look for signs of untrustworthy casinos to keep yourself safe.

Similarly, play responsibly and remember gambling is entertainment only, not a source of income.
