What Casumo Casino does well

After signing up at Casumo, we were awarded a casino welcome bonus of 50% up to £100 on our first deposit.

The online casino offers reliable customer support via live chat and email, and there's also a comprehensive FAQ section answering common issues you might face while on the site. For deposits and withdrawals, acceptable payment methods include Visa, Skrill, Mastercard, Neteller, and Paysafe.

We liked how swiftly payments were processed and that we could use Mastercard on our first deposit.

Where Casumo Casino should improve

Casumo could consider increasing the welcome offer validity period, which is currently seven days. Some online casinos we’ve signed up at also offer a loyalty programme with perks like dedicated account support, more bonuses, and cashbacks.

Casumo could also add a VIP programme for active players. We'd also like to see Casumo make the process of finding games more personalized by showing recently played games, similar titles, and recommendations based on previous activities.

What are Casumo's sister sites?

In this context, sister sites refer to online casinos that are owned by the same operator. Unfortunately, we didn’t find any Casumo sister sites. Our recommended alternatives all share different operators. We've chosen these sites because they, in their own way, provide similar features to those of Casumo.

Top 5 alternatives to Casumo Casino

Here’s our experience playing at sites similar to Casumo:

Mega Casino – Features a dedicated mobile app

Mega Casino immediately caught our attention thanks to its welcome offer. New UK players can make a first deposit of at least £10 and receive a 100% deposit match up to £25. We were also surprised that the welcome offer came with 50 free spins.

All you need to do is register, select the welcome offer, and make the qualifying deposit. We like the £10 minimum because it means you don't need to deposit a large amount to receive this offer. Mega Casino also features a gaming library with categories such as slots, jackpots, slingo, scratch cards, video poker, and table games.

Want to play on the go? You can check out the Mega Casino mobile app available on both the Google Play Store and the Apple App Store.

bet365 – Best casino welcome bonus with up to 500 bonus spins

We've included bet365 because it's a good option for players seeking an exciting online casino experience. You can sign up to claim up to 500 bonus spins when you make a deposit of £10. We were surprised that the online casino also offered a welcome package for new poker players.

The package offered up to £365 in rewards and required an opt-in. Before claiming any offer at bet365, read the terms and conditions first.

bet365 also features a decent game lobby where we found slots, table games, poker, jackpots, a live casino, bingo, and exclusive titles. Our recommended titles include Eruption Blaze Chasingo, Super Spin Roulette, Blackjack First Person, 8 Immortals, Space Odyssey, and Gates of bet365.

Megaways Casino – Features a VIP programme

We signed up at Megaways to see if we could find any other games aside from what was available at Casumo Casino. The site features hundreds of slots, table games, a live casino, and jackpots, all from popular game developers.

Our favourite titles to play were Viking Runecraft 1000, Thor: The Trials of Asgard, Ice Fishing, Monopoly Live, and Fortune Roulette. We were also quite impressed with the site's selection of live game shows. Megaways rewarded us with 100 free spins on Fishing Frenzy Big Catch Megaways after we signed up and made our first deposit of £10.

We like how the offer is simple to understand: make a deposit, receive your spins, and use them on the selected game. Megaways also features a VIP programme where you can enjoy exclusive perks such as tailored rewards and dedicated account support.

MoGoBet – Offers multiple existing player promotions

Another alternative on our list is MoGoBet Casino. The site offered us a 100% deposit bonus up to £50 and 20 free spins on Book of Dead. We also made a deposit of £10 to claim this offer. Deposits using Skrill or Neteller don’t qualify for the bonus.

Another reason why we added MoGoBet to our alternative sites list was thanks to the multiple casino promotions available. These promos gave us extra spins to use on selected games.

Participating is easy, as you'll only need to opt in. For example, with the Weekend Wheel of Spins offer, we received up to 500 free spins by spinning a wheel daily after making a deposit of £20 or more and using the appropriate promo code. We recommend checking out the banners on this page to visit the official site and see what offers are available.

Star Sports Casino – Offers secure payment methods

The first thing we noticed after signing up at Star Sports Casino is that there’s no dedicated welcome offer for new players. However, the site does offer two promotions that both new and existing players living in the UK can claim, which you'll find at the top of the page.

Deposits and withdrawals at Star Sports Casino can be made using Mastercard, Visa, Maestro, and bank transfer. We verified our identity before we were allowed to process payments. Verification on the site included submitting a government-issued ID, proof of funds, and proof of address.

We liked how Star Sports gave us the option to set daily, weekly, and monthly deposit limits before signing up. There was also an option to turn on the reality check. Check out the site's Safer Gambling page for more information.

Here's a table showing how these sister sites compare for welcome offers:

Factors to consider when checking out the best Casumo alternatives

Searching for the best online casinos like Casumo Casino isn't just about finding the one with the best welcome bonus. Just like when we compiled our list for the top QuickBet Casino sister sites, we took lots of factors into consideration.

Here are some of them:

UK Gambling Commission licence

This is actually one of the first things we check. An online casino accepting UK players needs to have the appropriate UK Gambling Commission license. We don't just rely on the logo displayed on the website alone. Instead, we check the site license information thoroughly.

Game selection

One thing we encourage players to check first is whether the site they're signing up on actually offers the games they like. If you're the type to play mainly slots, then look for providers and game types you recognize. For live casino enthusiasts like us, we usually check for the number of live tables available.

Payment methods

Unfortunately, an online casino can have the best game collection and still not be the right fit if the site doesn't offer your preferred payment method. We usually go for sites that offer secure and reliable options.

Before making deposits and withdrawals, we emphasize the need to confirm minimum and maximum transaction limits for each payment option. We also check to see if a particular payment method has any restrictions attached.

Payment methods we normally look for include Visa, Mastercard, and Apple Pay. Most of the time, these online casinos display available options at the bottom of the page.

Mobile experience

To be honest, we don't really want to be tied to a desktop computer to play casino games. A good Casumo Casino sister site should load properly and make the lobby easy to access. The site should also allow us to easily manage deposits, withdrawals, and even account settings from the comfort of our mobile devices.

Most of the time, it's a lot better when the site features a dedicated mobile app, like Mega Casino, for example.

Promotions for existing players

The welcome bonus at an online casino isn't everything. When we compiled our list of similar sites like Casumo Casino, we wanted to make sure that the sites also offered promotions for existing players in the UK.

If you check our article on Hollywoodbets Casino sister sites, you'll notice how we also considered the kinds of bonuses new and existing players could claim. We wanted players who signed up to have multiple bonus options.

Customer support

Signing up at an online casino that offers great customer support can end up saving you lots of stress. We always consider whether support is available through email, live chat, or even an FAQ section.

Responsible gambling tools

Finally, we'd say responsible gambling tools deserve just as much attention as the bonuses you'll find at these online casinos. We recommend checking for tools like deposit limits, time-outs, self-exclusion, and any other tools that let you stay in control.

The main essence is to have options that can help you step back when your time on the site stops being enjoyable.

What games can you play at sites like Casumo Casino?

When reviewing our recommended alternatives, we suggest checking out the game lobby first. The exact titles might differ depending on the casino, but you'll find that they all offer similar categories.

Let's take a look at what you might find:

Slots

We don't think there's any online casino you'll sign up at that doesn't offer slots. Even when we searched for NRG Casino sister sites, we were very intentional about which slots were available. You might find simple three-reel games, modern video slots with cascading reels, bonus rounds, multipliers, progressive jackpots, and other features.

Also, check the number of games available from top software providers rather than only looking at the number of slots. Since these similar sites are available to players in the UK, there are certain rules you'll need to note for slots.

There's a £5 maximum stake per game cycle for players 25 and over, while a £2 maximum stake per game cycle applies to players aged 18 to 24. Just so you don't get confused, game cycle here means the period from the game starting until all the money wagered is lost or all winnings are available.

Table games

Some of our Casumo Casino substitutes also feature table games like blackjack, roulette, and baccarat. The important thing here is variety. You can scroll around the site's page to see what exact variations are available. From our research, you might even find exclusive titles available.

Live casino

The live casino is another category you might find at our similar sites. Instead of playing against an automated game, you'll be able to play with real dealers. Depending on the sister site you sign up at, you might find live blackjack, roulette, baccarat, and even game shows.

Jackpots and specialty games

Some of our Casumo Casino-like sites also offer jackpot and crash-style games.

Conclusion – Casumo Casino has some interesting alternatives

After checking out Casumo and the other online casinos on our list, the bottom line is that you don't have to stick to one site just because you like all of its offerings. We found that each of these alternatives has something different to offer.

Starting with Mega Casino’s dedicated mobile app, which makes gaming on the go a lot easier. Megaways also had us looking at its slots and VIP programme, which offer exclusive rewards. We also like the selection of existing-player promotions at MoGoBet, while the bet365 welcome offer made us head straight to the game lobby.

If you're still a bit unsure about which alternative is right for you, we recommend comparing the current bonuses, games, payment methods, and even terms before signing up. Offers can change, so check the site frequently to see what's available to you.
