What Makes The Best No Deposit Free Spins UK Offers

No deposit free spins offers are pretty rare - most casinos or slingo sites require players to make a deposit before they can be awarded any free spins. If you do find a no deposit offer - like the ones of this page - you should make sure you snap it up immediately! Even though all free spins no deposit offers are worth claiming, there are a few elements that make the best ones stand out.

The first factor to think about is how many free spins you’re getting. As no deposit offers are risk-free for the player, you usually don’t get a lot of spins, so anything from five upwards is a good offer. Sometimes you can find an offer giving out 10 or even 50 free spins without requiring a £3 minimum deposit casino, so it’s absolutely something to check before you sign up for your account.

Wagering requirements are also very important. The vast majority of the best UK online casinos apply wagering requirements to no deposit free spins, which means that you’ll need to play through any free spins winnings a certain amount of times before you’ll be eligible to withdraw any cash. Some bonuses apply really high wagering requirements to this type of free spins offers - anything between 35x and 50x is relatively standard. There are very few casinos that offer wager-free no deposit free spins, but these are really the gold standard. If you have any win at all, you’ll be able to withdraw and keep your money!

In addition to wagering requirements, casinos also apply win limits to promos, especially a no deposit offer. This is simply a way for an operator to cover itself and to prevent, for example, a new player winning a big jackpot and not playing again. No deposit free spins often have a win limit of £1, £5, or £10 per free spin. Any winnings about this amount will be forfeited. The best no deposit free spins offers don’t have any win limits, so you’ll be free to land yourself a huge win!

You might find that casino brands only give you a certain amount of time to either claim your bonus credit, use your bonus credit, or meet the wagering requirements. This is usually a pretty standard timeframe like seven days or 30 days, but again it will be specified in the T&Cs. Time limits are not usually a problem, you’ll just need to plan out when you’re going to use your bonus credit and how you’ll meet the wagering requirements within the specified time frame.

The final factor to keep in mind is that more and more free spins offers aren’t usually valid on all games. Sometimes you will be restricted to just one game, while others give the option to try out a few games (usually from a certain provider). The best possible free spins offers will give you a choice, while including some popular titles, and some high RTP games which offer a good chance of a win.

You can then click on the link and you’ll be taken to the Revolut casino website to sign up for your account.

No deposit offers don’t require you to deposit to claim, so you won’t even need to visit the cashier section.

Free Spins on Sign Up Offers Terms and Conditions

It’s important to keep in mind that all fair casino promotions, including free spins offers, come with T&Cs. While some of them are standard, many differ between different free spins casinos offers, so it’s important to always read the T&Cs before you sing up for an online casino account, or claim any promotions. The most important T&Cs to look out for include wagering requirements, win limits, time limits, and game limitations. If you are wanting to try the best online scratch cards then there is no point taking a free spins offer.

Firstly, most online sites don’t allow you to use your free spins on all games. Usually, free spins are give on one slot game, or a selection of a few, and depending on the casino you might be able to use some spins on one game and some on another, or you might need to stick to one. The game restrictions are usually front an centre, for example a casino brand might advertise “10 free spins on Book of Dead”.

Wagering requirements are perhaps the most important condition applied to free spins. Most free spins offers require to to play through winnings 35x - 50x, but some might be as high as 70x. Usually, slots count 100% towards wagering (with some exceptions like jackpots and high RTP games), while live dealer and table games contribute less.

Some casinos might also limit the amount you can win per free spin. Don’t worry if you do win more than this, as additional winnings will simply be forfeited. Another way you might forfeit yours winnings is if you don’t claim your bonus, use your free spins, or meet the wagering requirements within a certain amount of time.

Also remember if you are taking a no deposit offer you will need to register a payment method if you want to withdraw winnings. A pay by mobile casino, casinos with Apple Pay, Skrill casino, Trustly casino UK, AstroPay casinos, or Paypal casino sites will probably still need you to register bank details or a debit card. That can be done with Mastercard casino sites or be circumvented with the use of Paysafe casino sites. Credit cards like Amex casinos can't be used in the UK.
