River Monster Review: Is River Monster Legit or Scam?

Last Updated on 07/06/2024
Fact checked by: Josh Schwartz

New sweepstakes operators are launching all the time across the US, and here at Captain Gambling we make sure we take a look at every single one. And that includes the River Monster Casino.

Unlike the majority of free-to-play casinos that we check out, River Monster keeps its cards close to its chest - and that’s never a good look for any gaming site. But we believe in giving every sweepstakes site a chance, so we took a closer look under the hood at River Monster.

About River Monster Casino

One of the first tasks we undertake when reviewing any gaming platform is to check out its licenses and security protocols. But of course, since River Monster Casino is a sweepstakes site, no license is required - after all, no real money wagering ever takes place.

Even so, we still expect every sweepstakes operator to proudly display its company registration details, and at the very least its registered address. River Monster seems to be curiously unwilling to part with even this most basic information, which instantly puts us on alert. We’re not saying that River Monster isn’t a safe and reliable platform - but we are saying we couldn’t find any firm evidence to show that it is - and that’s a real red flag as far as we’re concerned.


The River Monster user experience

Although you can complete the River Monster Casino registration process from the website landing page, you’ll need to download the app to start playing games. We took a look at the signup details required, and were pretty concerned by what we found. You’ll need to agree to an unspecified ‘subscription agreement’, while the terms and conditions are some of the vaguest we’ve come across.

As we made our way through the introductory text on the landing page, we were struck by the fact that it doesn’t read particularly well. In fact, it felt as though it had been poorly translated from another language, which again, doesn’t bode well in terms of the overall player experience. Any self-respecting operator would want to make sure that explanatory text is as clear and helpful as possible.

Original games at River Monster

The main attraction at River Monster is the collection of fish table games. They’re becoming increasingly popular among gaming fans, but so far only a very limited number of sweepstakes platforms offer the chance to play them.

River Monster also has a small library of original slot games, all with an aquatic theme, such as Baby Octopus, Crocodile Adventure, Ocean Monster and Fish Chopper. We took a look at a few of them, but to be honest, we think it’s the fish table games that will be of more interest to players. Slot features appeared basic at best, so if spinning reels is something you particularly enjoy, we think you’ll likely be disappointed by this collection.

No information about River Monster payments

Of course, we wouldn’t expect to come across any River Monster Casino deposit options, as this is a free-to-play sweepstake casino platform. And we were only able to track down limited information about River Monster bonus codes - although we did find a few details about an offer worth $5 in free play for everyone who registers for a new player account.

A lack of River Monster sweepstakes information

There’s absolutely no information provided about the free-to-play sweepstakes model or rules, let alone any details about how to claim Coins, or even what type of Coins are available. If real life prizes are available, we certainly couldn’t find an indication on how to action River Monster Casino withdrawals.

The owner of the brand - FlamingoSeven - seems to be more intent on selling its software and sweepstakes casino platform than it is on attracting players. And possibly one of the most telling pieces of information we managed to learn is that by offering your email address to River Monster, you’re allowing the operator to pass it on to third parties. If you’re determined to explore the fish table games we suggest you factor that in before deciding whether to go ahead and sign up.

There’s no Help Center that we could find, and no live chat. If you want to get in touch with River Monster Casino you’ll need to send an email or message them on Telegram. The operator is on Facebook and Instagram too, but doesn’t appear to be particularly active on either platform.

Conclusion of our River Monster Casino review

It’s all about the facts here at Captain Gambling, and sometimes that means telling a few harsh truths. Having explored everything that River Monster has to offer, we have to admit to finding too many red flags to ignore. We’d expect even the most modest of startup sweepstakes casinos to provide some basic information, along with detailed terms and conditions. Without giving us the ability to perform any detailed background checks on the brand, or its owners, we simply can’t recommend River Monster as a reputable sweepstakes casino platform.

That’s not to say that River Monster  isn’t legitimate, of course. And it seems very early days for the operator, so it’s possible it’s still putting the finishing touches to its platform - and we’ll keep an eye out for updates. But with so many reputable sweepstakes sites available, we know what we’d do. And we’ve got the full details of all of them right here, as well as the latest information about Luckyland promo codes, for example. After all - safe and entertaining gameplay is what Captain Gambling is all about!
