WinBig21 Casino Review

WinBig21 Casino is certainly Big when it comes to promotions. The ‘Home of The BIG’ as it bills itself on the home page, has been accepting customers since way back in 2012, much longer than the average online casinos. The site has a very simple blue colour theme and offers a ‘play now’ as well as a download option – however if you like to play online casino games, WinBig21Casino has you covered. Big Bonuses, Big Friends, Big Fun and Always Big are the catchwords of this site and they pride themselves on offering a Big Experience to all.


  • Android/IOS App
  • Crypto accepted
  • Biggest welcome offer


  • Very slow payment processing

Basic Information

WinBig21 Casino has been around for over 10 years and in this day and age, that is an impressive statistic. They are licensed in Curacao which is one of the most reputable places for a casino to obtain a license and ensures that all players are covered and games are fair. SSL encryption technology protects all user data too. As with most good casino sites, WinBig21 uses an RNG which is regularly audited to ensure outcomes of games are fair to both parties.

The mobile version of WinBig21 Casino has all the features of the web version allowing you to play all games, deposit and cashout funds, contact live support and anything else you need to do on your account. All games are optimised for the main mobile devices and although there is no App you can download from the App store, if you visit the website you can download software onto your mobile device and play that way.

The game selection isn’t the best and is perhaps the area the site is weakest. That isn’t to say they don’t have games including table games, slots and live casino games. They use providers such as Rival Powered, and live casino games from Fresh Deck studios. Life changing progressive jackpot slots can be played with your own cash and the navigation of games is very easy due to the layout of the site.

Bonuses are where the site comes into its own, on top of the welcome package as opposed to a one-off welcome bonus, there are regular reloads, cash back and ad-hoc bonuses available on almost every deposit if that is what you want.

WinBig21 Casino offers a decent range of deposit and cashout options such as cards, bank transfer and a number of the biggest crypto currencies including Bitcoin, Ethereum, Litecoin and more – There are even extra bonuses for players that use Bitcoin when they deposit!

How to Register

To access the full suite of games on offer at WinBig21 Casino for real money, you will need to create an account. Below is a simple step-by-step guide on how you can do exactly that:

  • Visit the site and click ‘Play Now’ from the top of the page.
  • At the bottom of the next page, you have the option ‘Don’t have an account? Register!’ with a Register button below.
  • You will now need to enter a username, email address and password.
  • The next page requests your title, first name, last name, date of birth and mobile phone number along with country code.
  • The final step is to enter your address including country, currency which can be USD, EUR, GBP, ZAR or AUD and a secret question and answer for extra security.

After you accept the terms and conditions and verify your email, you will be ready to deposit and start playing!

Providers and Available Games

The site is powered by Rival Gaming and as a result, many of the casino games from this provider. You have a choice from a wide range of slots and table games, which is fairly standard across any good online casino. Games are easy to find as they are displayed in 12 different categories: Featured, New, Hot, Slots, Rival 3-Reel Slots, Rival I-Slots, Rival Progressive Slots, Rival Video Slots, Speciality Games, Scratch and Win, Table Games and Video Poker. Bonus funds can be played on most of the slots but not table games.

Each section also includes a small icon which displays further information on each game such as the number of reels, winlines and often a brief description of the game itself. Many games can be tried using free play before you use your own funds giving you a taster of what each is like. Reviews are available on most which you can add to if you wish, giving real player opinions on each game is a great way to choose which ones are best for you.

A lot of the games have the option of playing an enhanced or a lite option which is a good choice if your internet connection isn’t the strongest – the lite version removes a lot of sounds and music leaving just the basic gameplay.

Live casino games are available via the table games section. You will see an option for Fresh Deck Studios which will open a new lobby with many games available to play as if you were actually in a casino.

Bonuses and Promotions

The Biggest plus to WinBig21 Casino is undoubtedly the promotion side. As soon as you open an account, a welcome package as opposed to a one-off bonus is available and from there onwards large bonuses always seem to be available on every deposit.

On your 1st deposit, you can get 650% up to $3,250. Then, there is a 640% bonus on your 2nd deposit up to $3,200, a 3rd deposit bonus of 630% up to $3,150 and a 4th deposit bonus of 620% up to $3,100. To round off the welcome package, a 610% deposit bonus is available on your 5th deposit, up to $3,050.

We don’t blame you if you think that would be it, but if so you’d be wrong. Players are entitled to 20% weekly cashback each and every Monday, WinBig Reload Bonuses, a Bitcoin Deposit Bonus, a Big Midweek Bonanza, Comp Points which can be converted to cash and a Refer a Friend Bonus.

These may be the Bonuses advertised on the promotions page, but that isn’t all there is on offer. Most times when you log into your account you will have more ad-hoc bonuses on offer  and if you can’t find a Bonus that suits you try asking the live chat support which is available 24 hours a day, as they will often have more to offer as well.

Customer Support

Overall, we feel WinBig21 Casino is a great casino to play at if you like to use bonuses. We have not come across many other casinos that can compete with them either on the size of deposit bonuses on offer or the sheer number available. There are casinos that have a larger range of games available, that is the one downside we found, but other than that it is a very solid and reputable place to play.


Is WinBig21 Casino safe?

They have been around for over 10 years and that would not be the case if they weren’t a safe site. SSL encryption technology is used for every transaction and games are tested regularly on the RNGs so you can relax when playing knowing you will get a fair game.

Does the casino offer bonuses?

This is easily the best part of the casino, a crazy range of bonuses is available on almost every deposit if you want one!

What payment methods can I use?

WinBig21 has a good variety of deposit and cashout options including card, bank transfer and a number of crypto currencies.

Can I play at WinBig21 on mobile?

You can, there is no app available but all games have been optimised for use on the main mobile devices and you can download casino software from the website and play using that if you prefer.

Does the casino have good customer support?

Live chat is available 24 hours a day or email if you prefer, we found the agents we spoke to were very helpful and knew what they were talking about.
