Have you checked out the banking methods accepted?  Is the site welcoming to mobile players?  What are the wagering requirements on some of the bigger promotions?

It’s clearly something to do with the choice of games on offer – but there’s a little more to it than that.  Read on to learn more!

Welcome Bonus & Sign Up Offer

What is the first deposit bonus?

The 666 Casino welcome offer for 2024 will likely appeal to most players and is cheekily tied in with the site’s devilish theme and name.

The new player deal is 100% of your first deposit matched all the way up to £66, plus 66 welcome spins to use on the aforementioned game or any game which may be tied in with the deal in future.

That means you can get extra bonus cash to the tune of a 100% casino cash matching offer as well as an added set of extra spins to use.

The title involved with the first deposit bonus deal may change, so do check this before you take on the 666 Casino welcome bonus at your convenience.

That’s an interesting twist on the old welcome bonus standard and one which leads in well with what seems to be a fairly unique site.

You’re going to need to minimum deposit £20 to take advantage of this offer, though we doubt many gamers will have an issue with this to get started.

Wagering Requirements

It’s worth bearing in mind wagering requirements, too.  Most online casinos will request that you play back a certain amount of your own money before you withdraw winnings – but only, of course, if you claim bonus cash from the site.

There’s a wagering requirement of 35x your deposit & bonus combined here.  That means you’re going to need to play back £4,620 of your own money if you want to claim the full £66 bonus available.

It’s not the most restrictive deal around, though some casual players may feel a little constrained by the amount they need to play back just to take winnings away.

There’s also a winnings cap applied to your bonus spins.  This means you’ll only ever be able to win £50 maximum. As stated, these winnings will be implicated in the wagering, too.

If you’re happy with the above terms, you’ll also be pleased to know that there is further cash matching available on your next few deposits, too.

You can get 50% matching on any deposits made all the way up to £66 on your next five pay-ins – which means if you have plenty of gaming cash available, you should be able to get plenty of play out of it.

However, what are the chances you take on all of the cash match deals?  Maybe not likely – but see how you go!

Ongoing Promotions

There are also plenty of other bonuses and deals for existing customers too – so keep a close eye on what’s coming up via the site’s main promotions and offers tab.

Do also sign up for any promotional emails to make sure you get first dibs on exclusive promotions in the meantime!
