I've been keeping an eye on Roaring 21 for a few years now, and I'll admit the site has gradually moved in the right direction. It launched in 2018 and runs on an Anjouan licence (ALSI-192407055-FI3), so treat it as an offshore brand rather than a UK-licensed one.
What stands out is the coupon-based bonus system — 450% on crypto deposits, 400% plus free spins for slots — an RTG-powered games collection and a set of network progressive jackpots. That mix is exactly what regulars come for. That said, the caveats are just as concrete: no live dealer section, no regular tournaments and a $4,000 cap on weekly withdrawals.
The official site looks stylish enough. Some players may find the design a little dated and too plain, but that is a matter of taste. Either way, the interface is easy to use and the colour scheme is easy on the eyes.
The top menu has these tabs:
The footer links to the terms and conditions, the About Us page, the responsible gambling policy, the FAQ and other pages with information players need.
Roaring 21 does not provide any working mirror sites. If you cannot reach the site, there are two possible reasons:
In the first case you can try other routes, but you would be breaking the law. In the second, do not bother trying to get in — you are not allowed to use its services anyway.
Roaring 21 is an international online casino operated by Entertainment Software Group N.V., with Entsoft Group Ltd (registration number 000042028) named as the brand owner in the corporate documents. The company behind the brand runs several other gambling sites. The brand launched in 2018 and cites Anjouan licence ALSI-192407055-FI3; the full details of the owner and the licence are in the terms and conditions.
Players can download a free desktop client to install on a computer, or simply play in the browser. Both routes give access to every game, bonus, jackpot and service. The Roaring 21 mobile casino is covered further down the review.
Roaring 21 is certified by Technical Systems Testing. This well-known third-party auditor has tested the random number generator used in the RTG games, and every month the company checks the casino's slots to confirm they are fair and that results are unpredictable.
The casino is part of the Central Dispute System, an intermediary that handles disputes between operators and customers. Roaring 21 is approved by several respected gambling publications, including Casinomeister and CasinoGuru, and holds a 7.6 rating and accreditation at Casinomeister. Their seals of approval are displayed at the bottom of the screen.
You cannot play at the casino, or even register, unless you are at least 21 years old. Verification is mandatory: the casino asks for a government ID, proof of address and copies of any cards you use, and may request a selfie or a short video call.
The site does not accept residents of a long list of countries, including the United Kingdom, France, Poland, Russia, Ukraine, Israel, Curaçao, Costa Rica and Nigeria. The operator is licensed in Anjouan. Availability and legality vary by jurisdiction — check your local laws.
Americans are allowed to open accounts and bet real money at Roaring 21.
The casino follows a responsible gambling policy and has strict rules in place to keep things safe. It offers customers the following tools:
The site is English-only, with no versions in other languages.
To start playing at Roaring 21, you need to register first. The procedure is about as simple as it gets.
After that you can log in, make a deposit in the cashier, claim a bonus and start playing. New customers only. Deposit required. Identity verification (KYC) required.
Roaring 21 has a solid games library. Most titles are slots, including classic three-reel machines. There are also table and card games, video poker, progressive jackpots and a handful of titles from other genres.
The lobby is organised so you can filter games by category and other criteria:
Any group can be sorted by release date, alphabetically or by other parameters. There is also a search bar for titles.
Anyone can try the games for free, and demo play doesn't even require registration.
With an account, every title is open to you, and there are no country-based game restrictions.
Slots are the core of this casino: they sit at the top of the lobby and almost every bonus is built around them. They run on Real Time Gaming (RTG) software. Each spin is determined by a random number generator, so there's no way to influence the outcome.
In the Games section there is a menu on the left. Slots are split by the number of reels:
Beyond slots, the menu has New Games, Progressives, Specialty, Casual Games, Table Games and Video Poker.
You can search by title and sort the list. The default is "Latest", so the newest games come first.
The themes vary widely:
There are brand-new releases here alongside familiar machines such as Buffalo Mania and Coyote Cash 2.
Before playing for real money you can open any slot in demo mode. It is free and helps you learn the rules, the bonus rounds and the bet sizes.
The site's terms mention live dealer games from Visionary iGaming, but I couldn't find a dedicated section in the public lobby — not before registration, and not after logging in.
New customers don't get a no-deposit bonus for signing up, although the terms and conditions do mention free bonuses. That suggests no-deposit credits can be awarded to existing players for certain achievements or simply at the operator's discretion.
Separate restrictions apply to them:
As you can see, the free bonus rules are anything but simple.
Bonuses are everywhere, with offers almost every day. The percentages are high, but the conditions are strict — you're better off knowing them before your first deposit.
How to claim a bonus
Bonuses are never credited automatically. Here's the sequence.
The code has to be activated before the deposit, not after. Only one code can be applied at a time. If you activate a bonus by mistake, you can remove it in the cashier or ask support to do it for you.
Welcome offers
The starting bonuses come in several versions.
Bonuses for regular players
Existing players aren't left out either.
For every regular bonus, crypto works out better: 5% more bonus and a lower minimum deposit ($10 against $35).
Shadow Gods offers
There are three separate bonuses for the new game:
All three carry 40x wagering and a win cap: you can withdraw no more than 40 times your deposit. With a $50 deposit, for example, the maximum is $2,000. The other deposit bonuses have no cap unless one is stated separately.
Key rules to know
All bonus deadlines are calculated in US Eastern Time (EST).
What counts as a breach
The casino can refuse a payout and void winnings if it suspects bonus abuse. Breaches include:
The rules in this part are worded broadly. Keep your bets simple and don't try to work around the conditions. T&Cs apply. New customers only. 21+.
Free spins come in two forms here: as part of a deposit bonus and as a standalone offer. Either way, you only get them by activating a coupon in the cashier.
Where to get free spins
There are several options.
How to claim them
The spins are added automatically. The code must be activated before the deposit. If the spins do not appear, message support before you start playing so support can sort it out right away.
Sometimes the casino hands out free spins without a deposit. Ask support about those. The rules for them are usually different, so read them carefully.
Crypto isn't a side option here — it's the main payment method. The minimum deposit is lower, the limits are higher, and some bonuses are open only to players who pay in crypto.
According to the Banking section, you can fund your account using:
Bitcoin is the only withdrawal route: timeframe: 1–2 days after the request is approved; casino fee: none; limits: from $30 to $4,000 per week. For comparison, a bank transfer costs $25 and takes 3–5 days, while a cheque costs $50 and also takes 3–5 days. That makes Bitcoin the fastest and cheapest route.
Keep in mind that the 1–2 days start after verification. The casino reviews a request within 3 business days once the account is fully verified, so in practice the money can arrive in 4–5 business days.
Here's how to play at Roaring 21 with crypto.
If you already know your way around crypto, none of this will be a problem.
Loyal customers who play at Roaring 21 regularly can expect a range of perks. They receive special bonuses, take part in events, use cashback and collect comp points earned on bets. Those points can be exchanged for cash, and VIPs may get exclusive bonuses and privileges. No tier table is published, so the program works more as an informal set of perks than a structured ladder.
Dreaming of a huge payout? Try your luck on RTG games with progressive jackpots. They can pay out substantial sums. The titles are:
All jackpot games are collected in a separate lobby section. You do have to bet real money for a chance to win.
If you're chasing jackpots, keep two casino rules in mind. First, network progressive games cannot be used to wager no-deposit bonuses. Second, they do not fall under the $4,000 weekly withdrawal limit, but the final payout is capped by what the payment partners can handle.
Gambling in mobile online casinos is as popular as ever, and Roaring 21 offers a mobile version that works on every modern platform and device. I opened it in the browser on my phone and on a tablet: the interface is adapted for touchscreens and nothing felt cramped. There is no dedicated app — everything runs in the browser, on Android, iOS and Windows alike. Slots, jackpots, bonuses, free spins and promotions are always within easy reach.
Transactions at Roaring 21 are processed in US dollars, Canadian dollars and euros, as well as in bitcoin and several altcoins. New players choose the account currency while filling in the registration form.
Deposits can be made with bank cards (Visa, Mastercard, American Express, Diners Club, JCB), bank transfers, Interac, bitcoin and some altcoins. The minimum for fiat methods is $35; crypto starts at $10. Payouts are made by bank transfer, cheque and bitcoin.
If you request a withdrawal by transfer or cheque, you pay $25 or $50 in fees respectively. Crypto payouts carry no fee.
To verify the account you need to send the casino copies of documents proving your identity, your postal address and the authenticity of the bank cards you intend to use.
Verification only counts as complete after the first successful deposit.
The terms and conditions cover all of these points in detail.
You can only use Roaring 21 after registering and logging into your account. Follow the link from Casinoz to the casino site. Fill in the registration form, sign in, and complete any remaining required details. After that head to the cashier and make a deposit — cards, bank transfer, Interac and crypto are all on the list.
Once the payment clears, you can claim your starting bonus and start playing.
Support is available by email and live chat, which the casino says is available 24/7. The FAQ section answers most routine questions, and the terms and conditions are worth reading before you deposit.
If you run into a problem with the operator that you cannot resolve directly, write to CDS. Its logo is in the footer.
Remember that Casinoz also accepts complaints about online casinos.
Roaring 21 is a genuinely solid online casino. Newcomers and regulars alike get a varied set of bonuses, take part in promotions, collect free spins and cashback, and earn comp points on their bets. Slots and other games are all available, jackpots included.
That said, Roaring 21 isn't perfect. There is no live casino and no regular tournaments, payment options are limited, and withdrawals are capped at $4,000 a week.
Before you register and top up your balance, weigh the strengths against the weaknesses. Casinoz experts consider Roaring 21 a solid pick for slot players who are comfortable with an Anjouan licence and the operator's 21+ age limit, and we'd suggest reading real player reviews first. Gamble responsibly. 18+. If you or someone you know has a gambling problem, seek help.
It is licensed by the government regulator of Anjouan, under licence ALSI-192407055-FI3, so it operates legally within that regime. The software is tested by independent auditors and the site is accredited by several gambling publications.
The portfolio includes slots, a range of card and table games, video poker, jackpot titles and more.
New players get a welcome bonus package. To claim it you need to register and make a first deposit.
You can play in US and Canadian dollars and in euros, as well as in popular cryptocurrencies including Bitcoin.
