The Online Casino Review

Last updated: 05 September 2025 Published by on 06 August 2025

With such a straightforward name, The Online Casino is the brainchild of ProgressPlay Limited, a reputable iGaming brand, and the platform was established in 2018. With multiple licences from strict regulatory authorities like the UKGC (UK Gambling Commission) and MGA (Malta Gaming Authority), The Online Casino is a legitimate and credible online gambling platform.

Legality aside, the online gambling site is known for its casino games and promotions. We were disappointed when we didn’t find a The Online Casino no deposit bonus or no deposit spins. However, the platform makes up for it by featuring several promotions, including multiple welcome offers registered UK gamblers can choose from. Besides that, the platform stands out for its extensive game collection, as you can find 1,000’s of The Online Casino real money slots, tables, bingo, and live dealer games.

The Online Casino Bonus

When it comes to promotions, few online betting sites can match The Online Casino’s bonuses. Though we didn’t find any no deposit bonus, we saw a noteworthy selection of promotions across its casino, sportsbook, and live casino sections. For example, newly registered and verified UK gamblers can choose between 3 welcome offers.

The Online Casino UK offers newly registered and verified users a warm welcome thanks to its casino welcome promo. When you create an account and opt in for this promo, you get a 100% up to £100 + 20 Spins on Book of Dead by Play’n GO on your first deposit of at least £10. Notably, while The Online Casino welcome bonus funds are valid for 30 days after being credited, the casino bonus spins have a 7-day validity period. Furthermore, deposits via Skrill and Neteller don’t qualify for the welcome offer.

Unlike most brand new casinos with single welcome offers, long-standing sites like The Online Casino feature multiple welcome bonuses. For example, the operator has a different welcome offer for UK sports bettors. When you choose this bonus and deposit £10 or more, you get a £10 bonus bet. However, to claim The Online Casino sports bonus, registered punters need to deposit at least £10 and stake the full amount on a sports event.

The bonus bet is offered once the bet settles as a one-time stake. Keep in mind that the bonus bet can only be used on a sports event with odds of 1.50 or higher, and it has a 7-day validity period.

Bingo Welcome Bonus

Registered and verified UK gamblers who prefer live bingo games can claim the bingo welcome bonus instead. If you select this welcome offer and deposit at least £10, you get £20 in bonus funds and 50 spins. 

Although these spins can only be used on Playtech’s Lucky Bass: Mega Cash Collect, the bonus funds can be used on all live bingo games on the platform. Similar to the casino welcome offer, the bonus funds expire after 30 days, while the spins are only valid for 7 days after being credited.

T&C for Wagering Requirements

The Online Casino has a few terms and conditions UK gamblers should know before opting in for any of its welcome offers. That’s why we’ve summarised a few important T&Cs of the welcome offers below:

Casino Welcome Bonus

The casino welcome bonus funds and winnings via spins are subject to a relatively high 50x wagering requirement. Note that this condition must be met within their respective validity periods. Remember that the bonus funds can only be used on eligible games, as some ineligible games are listed in the bonus T&Cs. Furthermore, while you can withdraw up to 3x the credited bonus amount from the bonus funds, the spins have a maximum bonus withdrawal cap of £20.

Sports Welcome Bonus

On the other hand, the sports welcome bonus has a 1x wagering requirement, which must be met within 7 days after the bonus bet is credited. However, the bonus has a maximum winnings withdrawal limit of £200, and the bonus bet must be used on a sports event with odds of 1.50 or higher.

Bingo Welcome Bonus

Although the bingo welcome bonus has a 2x playthrough condition, winnings via spins are subject to a 20x wagering requirement. You can withdraw up to 3x the credited bonus amount from winnings via the bingo bonus funds. Conversely, spins have a maximum winnings withdrawal cap of £20.

The Online Casino Design and Usability

The Online Casino stands out for its fast and intuitive website interface. Whether you want to visit the casino, sports, or bingo sections, navigating the platform is seamless thanks to its simple layout. In terms of speed, the website was fast across the numerous devices we used during our review. Its casino games loaded within seconds, and we had no interruptions.

Mobile Experience

Unfortunately, the platform doesn’t currently have a The Online Casino mobile app. However, that isn’t a considerable drawback, as UK users who prefer mobile casinos can still access the operator’s mobile-friendly website. We found the mobile site to be a suitable alternative to the desktop site, as it’s just as fast and functions well.

Games at The Online Casino

  • Live Casino Live casino

Notably, The Online Casino has 1,000’s of games in its lobby. The platform partners with over 50 game suppliers, including massive game studios like Playtech, Hacksaw Gaming, and Evolution. Hence, it’s not surprising that users can find a wide range of games, including slots, tables, and The Online Casino UK live casino games.

Slot Games

With thousands of slot games in the lobby, slots clearly make up the bulk of the operator’s game library. Besides varying in terms of themes, mechanics, and features, some of these titles are progressive jackpots. Notably, a large portion of its games are mostly from studios like Microgaming, Elk Studios, and Pragmatic Play. We’d recommend King of Sweets, Joker Spin & Roll, and Blue Wizard.

Bingo

Its bingo collection is just as impressive, as it features a wide range of live bingo games, covering popular variants like 90-ball and 75-ball bingo. That being said, some of these bingo rooms aren’t available 24/7; they can only be accessed at certain times. Nonetheless, we’d recommend Power Ball 80, Bingo Blitz, and Bouncy Balls Bingo.

BlackJack & Poker

Besides slots and bingo, the operator’s table game collection is also quite extensive. You can find hundreds of tables, ranging from blackjack and poker to roulette and baccarat. While many of these games are RNG games, most are live casino games. As a result, fans of live dealer casinos can play games like blackjack, roulette, and even game shows with live dealers. Software providers like Evolution and Pragmatic Play Live provide most live games on the site.

Sports Betting/Bookies

Registered UK sports betting fans can also find live and pre-game betting options across several sports leagues and events. The operator’s sportsbook covers various sports, including basketball, tennis, ice hockey, and darts. Notably, several esports are also available, including popular options like Dota 2 and Call of Duty.
