Rio de Oro Sister Sites 2025

If you look at the register of Internet Gaming Licenses in Anjouan, you’ll find Rio de Oro Casino listed under the name of CZM Invest Limidata, which is a Costa Rica-based company. You’ll also note that there are no other entries on the register, which means no Rio de Oro sister sites. We’re not totally convinced by that. We’ve noticed strong similarities between Rio de Oro Casino and other casinos based in Costa Rica and licensed in Anjouan, not least HotSpins Casino. Either this company works under multiple names, or there are casino network companies in Costa Rica sharing software. For now, though, we’ll take the operator’s word that this is a standalone brand. This page will be updated if that changes.

Rio de Oro Casino Review 2025

Let’s deal with this casino’s name before we get into anything else. It’s Spanish, and it translates into English as “gold river.” It’s also the name of a small region of the Western Sahara and a town in Colombia, but given the impression of a winding golden river in the casino’s logo, we think the intended meaning is obvious. It launched in mid-2025 as the debut brand of its operator (with the caveats we explained in the first paragraph of this page), and it looks clean and modern. Is there gold to be found in this casino, or will it leave you feeling like you’ve gone downstream without a paddle?

Rio de Oro Casino Welcome Bonuses

If there’s one thing that a new online casino absolutely shouldn’t do in any circumstances, it’s tell a lie on its homepage. Unfortunately, Rio de Oro Casino has done precisely that. The first banner you see on its landing page promises new players a 225% first deposit bonus with a maximum value of £3000, and “first deposit bonus” is precisely how the offer is worded. When you click through to the Promotions page, though, you’ll see that this isn’t the first deposit offer at all.

There is a first deposit promotion at Rio de Oro, but it’s 100% up to £1000 on deposits of £20 or more. That’s followed by 50% up to £1000 on deposit two and 75% up to £1000 on deposit three. You can claim the full £3000 that the homepage advertises, but it absolutely isn’t all attached to the first deposit. That’s a needless mistake for the casino to make and potentially a costly one when it comes to winning trust. Wagering requirements are x35 across the board.

Other Promotions

There’s only one other general bonus at Rio de Oro Casino, and it’s likely to be out of reach of the average player. If you fancy yourself as a high-roller, you can trigger a one-off 75% match up to £3000 the first time you make a one-off deposit of £1000 or more. If you’re able to do that, you also get the benefit of a lower x25 wagering requirement while you play through the bonus.

Rio de Oro Tiers Program

Rio de Oro Casino’s Tiers Program is a loyalty scheme that moves players up through a series of ranks based on how much they play. It starts with Iron (0–250 XP) and climbs through Bronze, Silver, Gold, Ruby, Diamond, and finally Infinite, which requires over two million XP. The benefits improve gradually with each tier. From the start, players earn shop points at a rate of 1 point per £100 spent, but the real perks begin at Bronze II, with 4% cashback on net losses. Cashback rates slowly increase, reaching 15% at Infinite, and discounts in the shop start at Silver I, improving to 12% for top-tier members. While this setup rewards high rollers, the pace is glacial; even mid-level tiers require eye-watering amounts of spending. There’s also no improvement in how points are earned, so even top players still grind at the same rate as newcomers.

Beyond cashback and shop discounts, the programme claims to offer “exclusive bonuses,” improved withdrawal limits, and quicker support, though these aren’t broken down in any meaningful way. The lack of clarity about how non-casino activities contribute or what actual bonuses are unlocked makes it hard to judge whether the system genuinely adds value. Most of the benefits only become noticeable once you’re deep into the Ruby or Diamond levels, meaning casual players will likely miss out. It rewards consistent, heavy spending more than anything else, and there’s no mention of loyalty counting for anything other than your transaction history. Overall, while the rewards are there, they’re skewed heavily towards whales, and the journey up the tiers feels more like a financial commitment than a celebration of loyalty.

What are the Pros and Cons of Rio de Oro Casino?

Pros: Rio de Oro Casino might be a decent place to play if you’re a big spender. You get an enhanced welcome bonus, and you also get the pick of the peak rewards in its tier-based loyalty reward system. The shop contains physical items like tech gadgets as well as rewards that can be used in the casino.

Cons: The advert for the welcome bonus on the casino’s homepage is misleading, implying that players can claim a big first-deposit bonus rather than three separate smaller ones. You’ll never get anything worth having from the loyalty program unless you’re spending millions. Rio de Oro doesn’t provide live customer support, fails to declare the terms of its withdrawal process, and has no relevant license to operate in the UK.

Top Slots and Games

Rio de Oro Casino offers a quirky, fast-paced library of games built around instant action and casual fun. Crash games like JetX, Balloon, and Zeppelin dominate the “Most Popular” section, joined by a swarm of Plinko variants from multiple providers, including GameArt, SmartSoft, and Funky Games. These are rounded out by instant win titles like Mines, Color Game, and Money Tree Dozer, creating an arcade-style atmosphere with low-friction gameplay and rapid results. While slot fans will find well-known titles like Wanted: Dead or a Wild, Zeus the Thunderer, and Koi Gate, the overall slot library is compact and a little random.

Where Rio de Oro really stretches out is in its live gaming selection, which is surprisingly broad. Players can dive into blackjack, baccarat, roulette, and poker tables powered by Vivo, LuckyStreak, and TVBet, with multiple language and style variants. Quirkier live options like Live Joker’s Wheel, Wheelbet, and 1Bet give the casino a bit of a game show vibe, ideal for players who like spinning wheels as much as spinning reels. It’s not your standard casino experience; instead, it leans hard into the fast-bet, quick-thrill ethos, with a strong live dealer backbone and plenty of offbeat charm.

Withdrawal Processing and Support

We’ve read the terms and conditions of Rio de Oro in full (someone had to), and they talk about the possibility of making withdrawals using either crypto or fiat currency. They don’t specify which cryptocurrencies, though, and they don’t also specify which fiat currency methods are supported. There aren’t any payment provider logos on the website to help us, either. To make matters worse, the terms say nothing about the speed of the withdrawal process. When withdrawals are fast, casinos tend to shout about it, so we’re suspicious for that reason.

Customer Support and Licensing

There isn’t any live customer support available at Rio de Oro Casino, and that’s pretty close to being unforgivable in this day and age. The casino doesn’t even list an email address. Instead, your only option is to create a ticket on the “Contact Us” page and hope that the casino means it when it says that someone will get back to you “shortly.”

CZM Invest Limidata, which operates Rio de Oro Casino, holds an Internet Gaming Licence in the State of Anjouan. The regulator there seems to us to be only too happy to hand out licenses to casinos regardless of how they operate, and the licence isn’t officially recognised in many places. The UK doesn’t recognise it at all, and the casino is illegal in the UK because of it. Nevertheless, the licence could still be extended to cover any Rio de Oro sister sites that pop up in the future.

Rio de Oro Casino – The Verdict

How do you feel about the prospect of playing at an online casino that misrepresents its welcome promotion, doesn’t have any live customer support, and can’t tell you how long you might have to wait for a withdrawal to be processed? If your answer to that question is anything other than “not good,” it might be time to step away from gambling for a while. There are just too many things wrong at Rio de Oro Casino for us to feel like we can say it’s an OK place to play regardless of where you live and no matter whether its limited licence would cover you or not. Rather than being a gold river casino, we fear it might be a river of something altogether less pleasant.
