666 Casino takes online gaming to a place with a little more edge. It offers the players not only a different overall atmosphere but also a unique overall design compared to most other sites. The design and the branding of 666 Casino might be seen as a little provocative to some, but it still rides the fine line of taking itself too seriously.
666 Casino was established back in 2017 and has been growing steadily ever since. This online casino offers devilish action through its huge offering of 2,500+ games, including blackjack, modern slots and a live casino. With a licence from the UK Gambling Commission (UKGC), operated by AG Communications Ltd, the light-hearted branding of the company and generous bonuses have hooked many gamblers.
One of the site’s best features is its dedicated mobile app, which makes it easier than ever to access the games that you love without needing to load up the website and log in. Below, we’ll explore the mobile app and its best features.
Fully titled ‘666 Casino – Online Slot Games,’ the 666 Casino mobile app is a great substitute for playing through the site. It maintains the on-brand devilish design of the website with a colourful and engaging design. Navigation through the app is simple, with a search function that enables gamblers to filter games by themes, providers, titles and genres, just like on the website.
Though the design may seem a little simple, it’s highly functional and allows players to look at thumbnails before selecting the game they want to try. There are over 900 slots available on the mobile app, plus table games and jackpot opportunities. While it includes many of the same features as the mobile browser version, playing on the app saves mobile data and battery and has greater connection stability and response times due to not relying on a browser to load.
The app is supported by both Android and iOS devices and can be downloaded on the Apple App Store and the Google Play Store. It has a current rating of 3/5 on the App Store and 3.5/5 on the Play Store, with over 10,000 downloads on the latter. There is app support available at [email protected]. If your app requires an update, it should appear when you open it on your phone.
Overall, 666 Casino deliberately opted for a simple layout to avoid over-engineering their app to achieve the highest functionality. This works because players can access games without worrying about the app crashing or malfunctioning during playtime.
The mobile app bonuses available for new and existing players at 666 Casino are similar to those available on the website. All ongoing promotions are advertised at the top of the homepage when the app is opened, keeping app players as up-to-date as those who play through the site, and there is an entire section dedicated to jackpots.
We recommend reading the Terms & Conditions of each of the following bonuses before getting started:
Immediately after downloading the app and making a deposit, players can access a Welcome Bonus of 100% of their deposit amount, which is instantly credited to their casino account. The minimum qualifying deposit is £20, and the maximum is £66.
For example, if your first deposit is £40, you’ll get a £40 bonus for the chance of playing with £80. On the second deposit (of between £20 and £66), you’ll get a bonus of 66 extra spins valid for the game “Big Bass Bonanza”. The wagering requirements for the welcome bonus are 35x, and it must be used within 21 days. One downside, however, is that the bonus spins expire after 24 hours, so players must use them straight away.
18+. New players only. Min deposit £20. Max bonus 100% up to £66 on 1st deposit. 66 spins on Big Bass Bonanza on 2nd deposit. 35x wagering applies, within 21 days. Spins expire after 24 hours. Gambleaware.org. Full T&Cs Apply.
This is a weekly promotion that started in March 2024 and will run until March 2025. There’s a total of £25 million for players to win in 364 Daily Tournaments (with a prize pool of £40,000) and 364 Daily Prize Drops (with prizes amounting to £30,000). Players can explore the ‘Jackpots’ section to explore more about these types of exciting offers on the 666 Casino app.
The tournaments allow players to win fixed cash amounts as described in the prize table, and a multiplier of the winner’s bet amount will be factored in for the Daily Prize Drop. The app promises all the real-money opportunities advertised on the website.
Complete challenges to win up to 50 spins on all slot games. This offer is available to all players who’ve wagered £100 or more the previous day on any slot game. Players can view their bonus offers under the ‘My Account’ section when they log into the app. The bonus is subject to a 35x wagering requirement, and any spins left unclaimed expire automatically when the clock strikes midnight.
You can use the 666 Casino app on your mobile iOS and Android devices with ease, thanks to the simple installation process. Enhance the user experience by saving your account details on a trusted device so you don’t need to input them every time you want to play.
If the app isn’t working, there are a few options players should try before emailing for help. Glitches or screen freezes can usually be fixed by quitting and restarting the app or restarting the entire phone. If there are any updates available on the app or the Apple or Google stores, enable those, and try to reinstall the app if it still won’t work.
If you have tried all of that and are still experiencing functional problems with the app, contact customer support by email at [email protected]. You should receive an answer as soon as possible.
The login process is the same on any mobile device. You simply open the app and use the details you registered with on the website. If you don’t already have an account, you can create one by following this easy process:
Once your account is created, use the username and password that you created to log in to the app and make a deposit to claim the welcome bonus.
Players using the 666 Casino App have access to all of the games in the casino’s lobby, including slots, table games and live casino games. The homepage may recommend some popular games, but players have full control over what they play on the app. There are several search functions, including ‘A-Z’, which allows you to organise games alphabetically, and ‘Recently Played’, which keeps track of your recent favourites.
