Discover New Online Casino Games

Developers are constantly releasing new online casino games and are always looking towards innovation. While classic table games such as blackjack, roulette and baccarat can only stray so far from the original, slot games don’t have such restrictions.

Slots have come a long way from the traditional one-armed bandits with simple fruit symbols, and with the move to online casinos, they’ve come even further! Slots developers keep releasing entertaining and fun video slots with new features and themes. 

As mentioned earlier, 666 Casino’s collection includes the latest online slot games. We want to offer our players all the industry has to offer. We have Megaways slots that could see the number of winning ways reach up to the hundreds of thousands. Some of our most popular games include Rainbow Riches Megaways and Eye of Horus Megaways.

We also have progressive jackpot slots, such as Blueprint Gaming’s Fishin’ Frenzy Big Catch Jackpot King (JPK) and Buffalo Rising Megaways Jackpot King.

These slot games are part of the Jackpot King progressive jackpot. A small portion of each player’s stake contributes to the jackpot, which increases until it’s won.

Our slots also cover a broad range of themes and settings, from ancient civilisations to outer-space and fishing-themed slots to Irish-themed slots.

You can find our collection of the latest online slot games under the “New” section of the navigation bar.

Play Live Casino Games With Real Dealers

Although online casinos are convenient, some players find they’re lacking that social element found in brick-and-mortar casinos. That’s where live casino games come in.

Live casino games work by live-streaming real dealers operating casino games straight to your device. You place your bets using the interface on your screen, and you can usually interact with other players and the dealer via a chat function.

666 Casino offers its players a great range of live casino games, including live blackjack, live baccarat, and live roulette games. We even have game show-type live games, such as Crazy Time, Monopoly Live and Deal or No Deal.

So, head on over to the ‘Live Casino’ section to browse our great offering.

Casino Online FAQs

You can find answers to our most commonly asked questions below:

Can you win real money playing casino games online?

Yes, demo/free versions are not permitted in the UK as per UKGC regulations. So all of our games are real money games, meaning you bet with – and can potentially win – real money.

How does a casino bonus work?

A casino bonus is an offer of, most commonly, extra spins or a deposit match bonus. You claim the bonus and play using the bonus spins or funds. Bonuses are nearly always subject to wagering requirements, meaning you have to bet the bonus amount a stipulated number of times before you can withdraw the funds or any winnings generated from them.

What is RTP?

The Return to Player (RTP) rate gives an indication as to how a slot may pay out. It’s the percentage of the money taken in by a slot game that it can pay back out to players over time. For example, a slot game with an RTP rate of 97% should, in theory, pay out £97 for every £100 it takes in. 

It is calculated by the developers as an average taken over a large sample of simulated spins (usually in the millions). Since it is an average over a long period of time, it may not be reflected in a short session. You could win more, you could win less, or you could win nothing at all. 

What are Live Dealer games?

Live Dealer games are online casino games where a real dealer is live-streamed to your device, and you have an interface where you can place your bets and chat with the dealer and other players. The dealer physically spins a wheel or deals cards in real-time, with the online players reacting to it. 

It offers a more engaging and immersive experience than playing online variations of casino table games against a computer/RNG (Random Number Generator).
