The 666 Slots Collection
You may be aware that slots are the most popular attraction at any online casino site. They span a range of gripping themes, and the best of them offer truly engaging gameplay. The world of slots development gives studios space to exercise their creativity, so these beloved games are always evolving.
Slots make up the vast majority of 666’s game selection. There’s a massive selection of more than 1,400 games for slot enthusiasts to delve into. The most popular of these, according to 666 Casino, are:

| Starburst | NetEnt | Re-spins, wilds, space-themed |

Traditional Video Table Games
Video table games offer a taste of classic casino games without a live dealer. They often have exceptionally high RTP rates and offer a fast-paced alternative to live-streamed games. These are beloved by fans of traditional casinos, but they’re suitable for beginners too.
666 Casino offers a great deal of variety in its table games. There are classic variants, as well as a few left-field ones too. These games are mixed in with the live offerings, but there’s no denying that the selection is truly impressive. Here’s a quick look at what UK players can expect to find:
- Blackjack – Single Deck, European, Multi-hand
- Roulette – European, French, American
- Baccarat – Classic, No Commission
- Poker – Casino Hold’em, Three Card Poker
Live Dealer Experiences
Live casino games offer an immersive simulation, streamed in high definition from a real table with a professional dealer to your device. These are popular with both traditional players and newcomers, and the games are played for real rather than underpinned by random number generators, as is the case with their video table game counterparts.
Many slot players like to dabble in live casino games from time to time. If you’re one of these, then 666 is the right casino for you. Most sites offer just a handful of live games to supplement their slots, but in the case of this online casino, the selection is huge:
- Live Blackjack
- Live Roulette
- Live Baccarat
- Live Poker
- Game Shows
- And many more

Bonuses are region-specific, and here we’ll be looking at the bonuses that UK players can expect. Generally, they span welcome bonuses, bonus funds and regular free spins. Keep reading for more details.
Welcome Package
The 666 welcome bonus consists of both free spins and bonus funds, which are spread across your first two bonuses. Here’s how it works:
You get a 100% bonus on your first deposit, up to a maximum of £66. On your second, you get 66 spins to use on Big Bass Bonanza.
| Bonus Description | Up to £66 + 66 extra spins across two deposits |
|---|---|
| Slot | Big Bass Bonanza |
| FS | 66 |
| Bonus Amount (Cash) | £66 |
| Min Deposit | £20 |
| Bonus % | 100% |
| Wagering Requirement | 35x |
| Bonus Conditions | Use within 21 days |
This bonus is likely to prove popular for a couple of reasons. For one, 35x wagering is relatively low. Also, the fact that spins are for use on Big Bass Bonanza is good news, because this game has a high RTP rate.
