4Grinz Flash Casino

4Grinz Flash Casino is a Bitcoin-based gaming site that's been operating since 2015. You can tell that this is a Bitcoin casino thanks to the flying crypto-coin in the background.

4Grinz is licensed in Curacao, and the only country they restrict is the UK. This means that players from America and many other nations are free to play here. But should you bother playing at 4Grinz? Find out as we cover their bonus, promotions, games, and banking options.

4Grinz Casino Bonus

The 4Grinz Casino bonus is paid out over your first three deposits. The first deposit bonus (code WELCOME) is a 100% match up to 200 mBTC. The second bonus (code IMBACK) is a 50% match up to 200 mBTC. The third bonus (code RELOAD) is a 30% match up to 200 mBTC.

Note that you must meet wagering requirements of 45x the bonus before you can cash any deposit rewards out. Also keep in mind that you need to earn your bonus within the first 24 hours of playing. Many players will find this extremely restrictive, but it's what you must deal with here.

While we're not happy with the 24-hour window. However, 4Grinz partially makes up for this with daily promotions. One example includes Member Monday, where you can get a 50% deposit bonus. Another example is Wednesday Hump Day, where you receive a 75% deposit bonus.

Overall, we're really pleased with the amount of promos at 4Grinz. And the 45x wagering requirements are just slightly higher than the industry average.

4Grinz Casino Games

The best part about 4Grinz Flash casino is that you can enjoy lots of games from a wide variety of software providers. The providers include Amatic, Betsoft, Booming Games, SoftSwiss, Ezugi, Endorphina, and GameArt.

The fact that you can sample seven different providers allows you to experience different graphics and game styles from the slots and table games.

Some of the slots that you can play here include: 4 Seasons, A Christmas Carol, Admiral Nelson, Atlantis World, Big Panda, Blast Boom Bang, Blood Eternal, Chicago Nights, Cool Diamonds II, Eye of RA, Fa Fa Twins, Fire & Steel, Geisha, Heroes & Beasts, Jumbo Joker, Paddy's Pub, Satoshi's Secrets, Shaman, The Vampires, The Vikings, Under the Sea, and Wolf Moon.

You can play 4Grinz's casino games as long as you have the Flash program. This lets you enjoy gaming through your browser, no matter whether you're playing on a laptop, smartphone, or tablet.


The only banking option here is Bitcoin. That said, if you're not comfortable using BTC, then you shouldn't play at 4Grinz.

However, if you are interested in 4Grinz and haven't used Bitcoin, the process is fairly easy. All you need to do is set up a Bitcoin wallet and fund it through an exchange site. From here, you come back to 4Grinz Casino and make your deposit.

Customer Support

4Grinz customer service can be contacted through email and live chat. Also note that this casino offers 24/7 customer support, meaning you can always get a hold of reps.

Final Verdict on 4Grinz Flash Casino

Our favorite thing about 4Grinz Flash Casino is that you can sample several different gaming providers. We also appreciate how many different slots and table games are available.

This casino doesn't really have any major weaknesses, beyond the 24-hour window on earning deposit bonuses. Also, some players may find it cumbersome that they can only deposit with Bitcion. As long as you don't have a problem with this, then you should enjoy playing at 4Grinz.
