4Grinz Casino Review: A Bitcoin Casino You Can Trust?

4Grinz Casino has been providing Bitcoin casino players with more privacy, more freedom, and more rewards since 2015. This Costa Rica-licensed casino has the tagline—“Changing minds. Building trust.”—which reflects its aim to give its players top-notch security and service. Other than providing high-quality casino games and bonuses, 4Grinz goes beyond by teaching gamers why gambling with crypto is easy and fun.

You may be suspicious of this casino at first glance as it does not indicate its license and operator on the website. But with SoftSwiss as its platform provider and with names like Amatic, Betsoft, and Endorphina as its game developers, the gaming portal assures you it works with trusted brands. On top of that, it has an iTech Labs certification, so the games available are provably fair.

Since it is a Bitcoin casino, 4Grinz does not have any country restrictions, so you can play no matter where you are in the world. Signing up is also easy. All you have to do is provide an email address, a username, and a password before you can start playing.

Bonuses and Promotions

4Grinz boasts that it has every kind of bonus for every kind of player. Here are the rewards you can receive as a player in this casino.

Welcome Package: 100% Welcome Bonus

The casino offers a welcome bonus up to 200 mBTC on each of your first three deposits after signing up. Each of the deposits should be at least 1 mBTC. After you have funded your account, you must meet the 45x play-through requirement on non-progressive slots. Each of the deposit bonuses is valid for only 24 hours after activation, so make sure you play right away.

Grinz Points

4Grinz calls its comp points Grinz Points that you can earn when you play any of the games with Bitcoin. The casino has two types of Grinz Points: redeemable points and status points. The redeemable points are the ones you can exchange for bonuses, tournament entries, coupons, free spins, and rewards. The status points, meanwhile, determine your player status.

Player Levels

The more you play, the higher your ranking will be in the casino. You can reach the following statuses when you earn a certain amount of Grinz Points and meet certain requirements.

  • Free Premium Membership

You will become a Premium member when you earn at least five Grinz Points. When you reach this level, you will have the chance to earn free spins and giveaways, to join tournaments, and more.

  • Joy Luck Club

Join 1,500 Grinz Points in order to be promoted to a Joy Luck Club member. JLC members retain their Premium benefits and get additional rewards.

  • VIP Red, Gold, Platinum

You will achieve the first of three VIP levels when you collect 2,000 Grinz Points. Other than keeping JLC member benefits and additional rewards, you can trade your points for Bitcoin.

The good thing about playing on 4Grinz is that you do not need to deposit huge amounts to become a VIP. Just play any of the games in the casino more frequently, use the bonuses wisely, claim more wins, and wait until you reach the VIP status.

Daily Bonuses

4Grinz does not run out of bonuses as it gives you a chance to win something every day of the week. Here are the rewards that you can earn daily.

  • Member Monday – Premium members and above qualify for a 50% deposit bonus.
  • Twitter Tuesday – Tweet what you love about the casino to earn 10 free spins.
  • Wednesday Hump Day – Get a 75% bonus when you type a given code.
  • JLC Thursday – Joy Luck Club and VIP members get 10% bonus back on the value of their first deposit for that day.
  • Free Spin Friday – Premium members and above get 10 free spins on certain games when they deposit 3 mBTC into their accounts.
  • Chip Up Saturday – Join in any weekday deposit bonus and get a free 5 mBTC chip on this day.
  • All Bonus Sunday – Use the given code to get 30% unlimited bonuses on all minimum deposits up to 200 mBTC for that day.

With the casino offering lots of Bitcoin free spins and deposit bonuses, you will certainly have to play every day to earn as many rewards as you can. And because you do not have to make deposits to level up your status, it is easy to become a VIP member.

Games and Software

It might disappoint you that 4Grinz has only less than 300 games in its portfolio. Despite the short list, you will find games from trusted developers, so you know that you will enjoy high-quality gameplay.

You will not find all the popular slot titles, but you can spin the reels of enjoyable games like Eye of Ra, Casanova, and Diamond Vapor. The table game selections, on the other hand, are fewer but have reasonable variants of roulette, baccarat, poker, and blackjack. Unfortunately, Bitcoin dice games, keno, and live games are not available in this casino.

On the bright side, 4Grinz allows you to play any of its games for free. If a title interests you but you are not sure if you want to wager on it yet, you can use the Play for Fun option. Just remember that you are not qualified to get any bonuses and to earn Grinz Points while you are playing the free version.

Banking Methods

The only payment option available in 4Grinz is Bitcoin. If you are a fiat currency holder, you will need to have your money converted to the digital currency first. If you are new to Bitcoin, you can check the helpful FAQs that the casino has compiled for first-time crypto gamers.

To start playing, you must deposit at least 1 mBTC. The gaming hub allows you to deposit as many bitcoins as you want into your account. After you make a deposit, the amount will be credited to your gaming fund balance instantly.

If you want to withdraw your winnings, you can cash out at least 2 mBTC. 4Grinz promises your withdrawal request will be verified in an instant, and you will get your money right away. But if you are withdrawing 5 mBTC or more, 4Grinz will pay you out the amount in up to 10 equal installments. Do not worry because the casino cares about the security of your money. That is why it implements a strict security procedure.

Should You Play in This Casino?

If you look beyond the lack of information on licenses and operators, 4Grinz Casino looks credible. It runs on a recognized platform and it houses games developed by familiar providers. But so that more players can trust the casino, it should consider being more transparent with important background information.

When it comes to games, 4Grinz offers a moderate amount in its collection. Still, it should consider adding popular titles in order to attract gamers who would like to play something familiar. The casino should also think of adding live games so that players can experience betting as if they are in a brick-and-mortar casino.

Despite these issues, 4Grinz has proven to be a great casino choice for Bitcoin bettors. For one, it provides excellent service through helpful customer support. It understands the players’ need for security, and it makes sure it follows the strictest procedures without sacrificing the hassle-free transactions. And if you are after rewards, this casino has different bonuses in store for you every day. Maybe 4Grinz is not yet the most trustworthy casino out there, but the service and the incentives might encourage you to sign up anyway.


Navigating a casino for the first time is not easy, and 4Grinz make sure you will get all the help you need through its 24/7 live chat option. Just type your question and expect a friendly staff to address your concerns within seconds or minutes. You can also leave a message through the Contact Us form on the website, or you can email the casino directly.

To become more available to players, 4Grinz has established a visible presence on social media. You can follow the casino on Facebook, Instagram, or Twitter to get the latest news and updates on promos. This online casino also has a YouTube account that posts videos for players who are new to Bitcoin gaming.
