Evaluating 666 Casino's Look & Feel - What to Expect as a Player4.5 /5
666 Casino’s clean interface and well-organised menu are the main reason why we scored this area 4.5/5. The rating is not the maximum one because there is no 666 Casino app to download.
Overall, the theme is white, with red and black elements. Despite being up-to-date, you will not find 3D or animated elements.
Editor’s Verdict for the Look & Feel of 666 Casino
| Usability features reviewed | Editor’s Verdict |
|---|---|
| Desktop usability | If you access the site on desktops, you will find this version easy to use. The main menu is located at the top of the layout, and you will see the main game categories in the middle of the page. |
| Registration process | 666 Casino login process takes less than 1 minute as long as you’re a registered member. Also, you must complete the KYC procedure before playing here, but it will only take 1 day for the team to check the documents. |
| Site performance | We used a Gmetrix tool to assess how well 666 Casino functions. Also, our team tested the functionality on various smartphones and on Mozilla, Chrome, and Opera browsers. Our conclusion is that this operator performs well, as we did not experience any interruptions with the games. |
| Site organisation | The casino UK site has the main menu in the top bar of the screen. Below, you will see the main promotion. In the middle of the screen are the different game categorisations and a search bar. Also, you will find a drop-down list with the available developers. At the bottom of the layout are all the other relevant aspects of the site, including the T&Cs, FAQs, and contact options. |
| Mobile usability | The 666 Casino mobile phone version is simple to use and it is pretty similar to the desktop one. A difference would be the main menu, which appears in the left-hand upper corner of the page, with tabs for Promotions, Games, Sign Up, and Login. |
| App usability | For the moment, you will not find an app to download, so we recommend you stick to the 666 Casino mobile version and use the browsers. Also, you should not download any other apps that might resemble this online site since there is no official one developed yet. |
The site is pretty modern and intuitive to use, no matter the device you’re accessing it from. If the lack of apps is a dealbreaker, then you can check out Jackpotjoy’s iOS and Android applications and play anywhere.
666 Casino Slot Games - Our Expert's Take on Slot Types and Providers5 /5
With over 2,500 slots to play, 666 Casino boasts one of the broadest online slots portfolios for UK punters to enjoy. You’ll find leading titles from the likes of NetEnt, Microgaming, and Pragmatic Play and even newer studios that offer fresh mechanics.
The slot library contains classic three-reel slots, modern video slots, and progressive jackpots with bets from £0.10 to £100 for a spin. However, we noticed that there are some of the high-end developers not present that are available from other slot casino sites. There is not much tournament selection, but the search function enables you to conveniently locate specific games.
Slots Verdict
- Slot Selection: Excellent variety with 2,500+ titles
- Slot Providers: Good range but missing some premium studios
- Slot Types: Comprehensive coverage from classics to progressives
- Min-Max Bet: £0.10 – £100 accommodates all player budgets
| Game | Provider | RTP |
|---|---|---|
| Diamond Jackpots | Blueprint Gaming | 94.12% |
| The Goonies | Blueprint Gaming | 96% |
| Burning Wins | Playson | 96.21% |
| Chilli Heat | Pragmatic Play | 95.54% |
| Legacy of Dead | Play'n Go | 96.58% |

Slingo666 Casino's Live Casino - Review On Game Types, Quality and Betting Limits5 /5
The live casino section presents 263 live casino games from professional studios with real dealers. Several variants of roulette, blackjack tables, baccarat games, and modern game shows were accessible during our test sessions.
Betting ranges from £1 to £5,000 per hand, accommodating low-stakes players and high rollers alike. The majority of the tables are provided by Evolution Gaming and Pragmatic Play Live, with high-quality streams and professional dealer interaction to be expected. The greatest advantage lies in game variety, while table availability during peak hours can become restricted.

| Game Type | Variations | Betting Range | Providers |
|---|---|---|---|
| Roulette | European, American, Lightning | £1 – £2,500 | Evolution Gaming |
| Blackjack | Classic, VIP, Party | £1 – £5,000 | Evolution Gaming |
