Casino games have come a very long way in terms of tech, and now bursting onto the scene are live dealer games and live game show style games streamed straight to your phone in real time and in ultra-high quality.
Deposit method wise, more and more options are available all the time, not just Visa and MasterCard debit cards, but PayPal, Neteller, Skrill, Trustly and speedy Bank Transfers.
Being based in the UK, we are really well placed to thoroughly check out what options are available for UK players as and when they come onto the market. Of course, you’ve got your oldies like SkyVegas and William Hill, but there are many more options available to you in terms of online casino.
How do you go about picking the best online casino to start your journey at or indeed to switch to if you’re a little bit bored of where you are playing at the moment? Well, it’s really simple. First of all, check out what offers there are available to you as a new player right here.
Remember to always gamble responsibly and never bet more than you can afford to lose.
A great way to check out a brand new online casino platform is to sign up as a new player and grab their welcome bonus. In particular, see if you can find a no wagering deal—because with one of these deals, if you do happen to win from your free spins, then you can withdraw instantly with no playthrough requirements.
Online casino bonuses most often come in the form of free spins, but you’ve also got deposit match bonuses where your initial deposit is matched up to a certain percentage (most typically 100%). Few and far between, you have the no deposit bonus (although these are slowly being phased out due to bonus abuse).
If you’re after a casino bonus for spending less than £10, have a read of our article: the best £5 deposit bonuses for UK players where we’ve listed a choice of reputable online casinos and slots sites offering bonuses for depositing just a fiver.
So go ahead and grab yourself some free spins, why not? Once you’ve verified your age and made your initial deposit, the spins are normally auto-credited to your account; but if not, there may be a bonus code that you need to enter.
🤔 Remember, terms and conditions always apply with every bonus you claim.
