Roaring 21 is another USA-friendly online casino that caught the eye of the CasinoWhizz team. We decided to see what’s cutting with this site because we dig its theme.

It’s quite a new online casino since it opened its virtual door for business in 2018. They accept cryptos for fast withdrawals, USD, and CAD.

The theme harks back to the Roaring 1920s when life was simpler and when bootleggers reigned supreme. We cover Roaring 21 Casino’s RTG games, bonuses, promos, support, and banking options.

Moreover, by the time you’ve read through this review, you’ll know whether the site is worth your time or not.

What Does Trustpilot Say About Roaring 21 Casino?

trust iconAt the time of writing the review of Roaring 21 Casino, there were no player comments at Trustpilot.

Naturally, we snooped around to see what other top gambling sites had to say about it.

One gambling guide’s player comments stood out for us. They gave it an average rating of 8.9/10 which is exceptional.

That makes Roaring 21 one of the best casinos online where Americans can play legally.

Non-payments, tight games that seldom pay, verification delays, and their bonuses have steep WR.

Other than those few complaints, players said that they enjoyed their games and quick payouts through Bitcoin.

By the way, one player said that he won $900 with a deposit of $36. That clearly shows that it’s possible to win a lot of money even with a small deposit.

The casino also has a representative at the site to help with any player issues. How do I ensure that I won’t have any payment delays at Roaring 21 casino online?

Verify your account with them after you signed up. The good news is that their verification process is faster than most US online casinos.

Before we forget. A player won $18,000 with a cashback bonus; they only paid her $350. Now, there is a reason for that in case you think the site cheated her.

The terms and conditions attached to their cashback bonuses have a max cashout rule. The bottom line is if you want to win plenty of money at the casino play with your own money.

And if you do play with a bonus, read their terms and conditions carefully.

How Does Roaring 21 Compare?

comparisonIn terms of overall reputation, Roaring 21 Casino competes with the best. That’s to say it holds its own against sites like BetOnline, MYB Casino, and Super Slots.

No online casino is perfect, and the aforementioned sites do a few things better than Roaring 21. For example, BetOnline allows you to bet on your favorite US sports, and it has a live casino.

Super Slots Casino has a higher withdrawal limit, and MYB Casino has more games as well as a VIP program.

Casino Games Catalog

games lobby

Each online casino game is compatible with mobile phones which makes them perfect for players on the go.

RealTime Gaming’s portfolio of games gives players a download and a browser option. The library of games includes slots, table games, video poker, progressive jackpot, and specialty types.

Online Slots

online slots lobby

The online casino only lists the games from one software provider and that’s RealTime Gaming. If you’re looking for a US casino online with more brands check out Cafe Casino.

Of particular interest are their Rival slots and the Hot Drop Jackpots. Once you sign up at Roaring 21 casino online you can pick and choose from old-time classics and new slots.

Our favorite online slot machines are Cash Bandits 3, Bubble Bubble 2, and Warrior Conquest. The latter slot has a unique game engine as it expands with each win. Line up three bonus symbols on the reels you’ll score plenty of free spins.

Blackjack & Table Games

table games

Roaring 21 Casino dishes up the usual blackjack variants and table game options. US players can pick and choose from blackjack, European and American roulette, Pai Gow, Three Card Poker, and many more.

You can only play the electronic versions of the games since they don’t have a live dealer casino. We believe that’s an oversight from RTG casino at the moment.

Blackjack Caribbean Stud Poker
Pai Gow Poker Perfect Pairs
Tri Card Poker Let'Em Ride
Red Dog

Although the house edges of the electronic versions are sharper. Our blackjack cheat sheet will help you when you play blackjack for real money online.

Video Poker

video poker lobby

The Casinowhizz team is passionate about video poker. If we’re not playing slots online, we’re playing video poker like Jacks or Better or Deuces Wild.

Since Roaring 21 Casino is a typical RTG casino there’s no shortage of video poker at its site. They offer big jackpots, RTPs higher than 98% and they’re easy to play.

If we can give you a pro tip, always bet the maximum 5 credits when you play video poker.

Aces & Eights Bonus Poker Deluxe Double Jackpot Poker
All American Poker Jacks or Better Double Double Jackpot Poker
Bonus Deuces Deuces Wild Sevens Wild
Bonus Poker Double Bonus Poker Loose Deuces

Progressive Slots

progressive slots games

We have no idea about the hit ratio of the RTG progressives. Word on the street is each of their 6 jackpot games pays out more than once a year.

Whether it’s the top cash prize or a minor jackpot. The crowd favorites are Aztec Millions, Caribbean Stud Poker, Megasaur, and Let’Em Ride.

Aztec’s Millions and Spirit of the Inca offer life-changing payouts of up to $1 million.

Specialty Games

specialty games

Fish Catch is a shooting game while Banana Jones is a board game like shutes and ladders. We also find it odd that European Roulette is on the specialty menu and not under table games.

  • Keno
  • Fish Catch

How Do Their Most Popular Real Money Slots Check Out?

Fortunes of Olympus – RTG

fortunes of olympus slot gameplay

Fortunes of Olympus by RTG immerses you in the world of Greek mythology. You’ll see legendary gods and mythical creatures as reel symbols.

The game’s 95% RTP is a drawback, but the 50,000x max jackpot paired with medium volatility offers a decent payoff.

The flexible betting range is from $0.50 to $50. Moreover, the layout has 3 rows, 5 reels, and 50 paylines.

The wild can appear on all reels and substitutes for other symbols, except the Scatter. Get at least 3 Scatters to activate the free spins.

During the shifting reels, the reels shift down one position. That reveals new symbols on top, and this sequence continues as long as you keep on winning.

Each spin adds 3-5 extra Wild symbols to the reels. Throughout the 12 Free Spins, enjoy multipliers ranging from 2x to 6x on each spin.

Mermaid Royale – RealTime Gaming

mermaid royale slot gameplay

Mermaid Royale from RTG delivers a captivating underwater theme with a jackpot of 2,000x your stake. The game features 5 reels, 3 rows, and 25 paylines.

Betting options range from $0.25 to $125 per spin. We love the Expanding Wild feature and the free spins that include up to three random boosters.

A stacked wild with a 2x multiplier makes its appearance on the 5th reel. The game also spices things up with a bonus row for re-spins with oversized 3×3 symbols on the middle reels.

Icy Hot Multi-Game – RTG

icy hot multi game slot gameplay

Hot Multi-Game flips the script on traditional slots by offering two sets of 3×3 reels with 10 paylines. The game appeals to budget-conscious and high-rollers alike, with bets ranging from $0.10 to $10.

The stakes are high, too, with a top prize of 5,000x your bet. The game splits the screen, showcasing its dual theme.

On the left, you’ll find the icy set of reels featuring light blue symbols. On the right, things heat up. Step up to the Bonus Wheel to snatch up various cash prizes.

If the Free Games logos align, 3 scatters trigger 12 free spins. Feeling lucky? Land the scatters on both reels and you’re in for 24 free spins.

Big Cat Links – RealTime Gaming

big cat links slot gameplay

Big Cat Links from RTG offers multiple jackpots: Mini, Minor, Major, Grand, and Super Grand. The game features 50 paylines on a 5-reel, 3-row grid.

Aim for the jackpot with a 50,000x payout. Payouts occur less frequently because it’s a high-variance slot machine.

In both base and bonus games, Lion and Lioness symbols can show up in big 2×2 or 3×3 formats. Score 10, 15, or 20 free spins by landing 3, 4, or 5 Scatters in one spin.

More free spins? You bet. Hit 3 or more Scatters during free spins and get an extra 5. Unlock the Fortune Link Mechanic by landing 6 or more Coins symbols.

This mechanic amplifies your chances to snag one of those coveted jackpots.

Our Review of Roaring 21

Almost everything about Roaring 21 online casino pumps. Back in the day, young women were into jazz and alcohol was against the law in the US.

Stuff We Like

With a diverse selection of RTG games, bonuses, quick deposits, and withdrawals, for the most part, it’s an okay site. The are a few areas the site can sharpen up though.

Stuff to Work On

We’re not too fond of the low weekly withdrawal limits. Despite the fact that the bonuses are massive their wagering requirements spoil the fun.

More games from other online casino software will give it more flexibility too. Admittedly, Roaring 21 is somewhat repetitive and shallow.

Verdict: Roaring 21 Casino Let the Good Times Roll!

legal iconRoaring 21 Casino celebrates the high-live of the roaring twenties like no other casino online. On the face of things, we’ve seen better.

The site’s decadent start-up bonus worth $12,100 for new players is huge. Capitalize on that and you’ll be as good as rain but be aware of the WR. It’s not all about bonuses and extravagant rewards.

The USA casino online treats players well, their games are safe and of course fair. Moreover, the casino pays its winners with Bitcoin in no time!

Americans will find oodles of entertainment far away from the corporate mainstream. To reach that next level.

The casino can increase its withdrawal limit, reduce the WR of the bonuses, and add more games. Other than those minor blips we give Roaring 21 Casino the nod.
