New No Deposit Casino: A Guide to the New Player


Now that we’ve given you our online casino slot sites reviews of the top 5 brands in the UK, we can dive further into how to make the most of your online gambling adventure. Obviously online casinos follow Vegas casinos and offer the full gambler experience of poker, blackjack and roulette with Live Dealer option on top of the classic slots, but in this guide we’ll focus on the spin machines because frankly, we like them the best!


The idea is to take advantage of the New Player Offer UK online casino and slot sites award their first-time players. Don’t waste this opportunity! Like the saying goes, it’s cash on the table. Most of the new gambling sites we reviewed give you the advantage of no deposit bonus, meaning, free spins before your even first deposit. Others offer the free sign up bonus after you make a deposit, which isn’t that bad if you think about it – you came to play and the free spins bonus won’t keep you going for that long.



How to Use the Deposit Limit Feature


It is advisable to decide on a limit for money lost. Many sites have a deposit limit feature, so make use of it since when you’re in a gambling mood you might lose sight of the bigger picture, a.k.a. the depths of your pockets. Even if you don’t use the deposit limit feature, when you feel you’re about to cross the sum you’re willing to lose, take your finger off the button, take a deep breath, and try your luck again another time. Worry not – those reels and paylines would be there after you worked your numbers and made sure your credit card is still intact.


Online casinos are about having fun after all. If you’re just into it for making money and don’t care or enjoy the experience – if the wild and scatter symbols don’t make you giddy – well, that sounds like the beginning of a slippery slope.


Last but definitely not least, make sure you understand each new online casino’s payout and withdraw policy.



The Advantages of New Online Casino Sites in the UK (and Elsewhere)


Brand new no deposit casino sites are worthwhile for their welcome packages, as we mentioned above. You can pick a site according to your preference of free benefits and bonuses or you can go for sites that have a range of new slot games, specifically new casino slots machines. That’s one of the most exciting advantages of new casino sites in the UK – different combinations of game offering. These sites invest a lot in offering their players the best experience as the competition is stiff and customer loyalty doesn’t play a role in this industry.


In terms of deposits, there is quite a range of offers. You have the new no deposit casino UK sites that give you free spins with no deposit required. Other new online casino sites in the UK give you a bonus on your first three deposits, ranging from 150% to 500%.


UK’s best new slot sites and new online casinos have filtering options and great category navigation to help you find a game to your liking. You may be a sci-fi slot fan or a loyal fantasy slots fan, but there is also a large range of playful new online slots games with cartoon or anime themes.


If you’re looking to hit the jackpot, and of course you are, it’s actually advisable to select new casino slot games with medium sized jackpots since you’ll have a higher chance to win real money, and hopefully plenty of it. Much like land casinos, new slot sites with a free sign up bonus or without one are less likely to payout from larger jackpots as these machines are programmed to payout according to their size – the larger the prize, the smaller the chance to win it.



New UK Mobile Casino & Slot Sites Offer No Deposit Bonus As Well


The adrenaline spike has begun, but your phone can’t even load your favorite new mobile slots! Before you start gambling, make sure that your smartphone is compatible with the browser requirements of new mobile casino UK sites or that your iPhone or Android operation system is up to date to handle the mobile casino apps.


Think of new mobile casino sites like any other high-quality gambling site. The graphics and the content demand a newly updated device that’s fast enough to process hours of fun so you could enjoy popular slot and casino games. If your device is a few iOS or Android generations behind, some sites have the option to lessen the quality of the display in order to accommodate this. Keep in mind that most newer slot sites will have an FAQ section that details all supported devices.


Most importantly, all sign up bonus, free spins offers and no deposit offers stand for new mobile casinos as well. Whether you play on your desktop or on the go, rest assured, you’ll get you’re your prizes and rewards.



How to Play New Slots to Win


Winning is all in the gaming and the betting strategies. One method is the “one pay, one win” strategy where you bet one large sum in the hope of winning bigger sums back faster. It’s a high odds gamble, but since you’re not in Vegas but rather play ‘against’ a software, it’s a one that might be worth taking as it saves you a lot of time and is highly effective. You just need to be able to restrain yourself from playing again and again.


Recently, progressive jackpots have sparked conversation due to their practical jackpot accumulation method. However, you may want to watch out since many new slot sites UK pool together to account for more non-winning plays. Therefore, we can’t stress enough for you to stick to smaller or medium sized jackpot slots. The payout is also lower due to all the needed playing hours for progressive jackpots.


The same goes for new video slot machine games. New online slots UK sites need to invest a huge amount for the video quality and often their return isn’t high enough to justify the investment, which is why they don’t tend to payout as well.



Withdrawal, Payout & Privacy Policies Explained


Making a deposit is a short and painless procedure, but what about withdrawals and payouts? These policies vary from site to site.


Reading through policies and terms can be extremely tedious, but you want to make sure you understand withdrawal and payout policies thoroughly before making that first deposit since the two are intertwined and impact each other.


The best new online casinos in the UK should have encryption and multiple servers with privacy shields to protect your payment information and data. You may also want to check if they share your information with third parties in their privacy policies.


New slot sites also have reliable support with a fast response rate. Support service is an excellent indicator of how well the site functions and if they can be trusted.


We hope you’ve enjoyed our tips and tricks to winning big and that you’ll benefit from the many deposit bonuses, free spins and large payouts our slot site review has to offer. We love updating our reviews, so stay tuned for more exciting sites and offers.


New Slot Sites FAQs


How Do I Find the Best New Slot Sites?

That’s straightforward – simply read our reviews. Our team of expert players knows everything there is to know about slot sites in the UK. We also know that you want to play the best new slots online, which is why we make a point of keeping our review lists up to date. This way, you can easily find out about new slot sites and secure any special deals.


Is It Safe to Play New Slot Sites?

If a new slot site has the necessary licensing, you can consider it safe. UK slot sites are granted licenses by the United Kingdom Gambling Commission. The commission requires sites to meet very strict criteria, including wording terms and conditions in a clear and easy-to-understand way and putting the right encryption in place. For sites that are not UK-based, you should still look for licensing details.


How Do I Know If a New Slot Site is Legit?

Along with checking for the necessary licensing information, it also helps to get your reviews from reputable websites such as Slot Spinners. We only review and recommend trustworthy UK slot sites that have appropriate accreditations in place. You can also search for a website on the UK Gambling Commission website to confirm its licensing status.


What Should I Play on a New Slot Site?

That really depends on which slots appeal to you. New slot sites often have good bonuses for new players, so you can’t really go wrong. Some sites even let you try certain games for free, which can help you decide which games and slot sites are right for you.


What Bonuses Can I Expect?

There are a few different bonuses that you can expect to encounter on a new slot site, including:


  • Welcome bonus. With a welcome bonus, the site usually matches your first deposit to say thanks for signing up. In other instances, you may receive free spins. However, this could be subject to wagering requirements.
  • No-deposit bonus. Some new slot sites don’t even require players to make a deposit for them to claim a bonus. They simply need to create an account on the site. Players can generally collect a limited number of spins and winnings might be capped.   
  • High-roller bonus. If you prefer to play with larger numbers, you may be eligible for a high-roller bonus. This bonus gives you additional rewards for depositing a higher amount of money. 


How Do I Win on New Slot Sites?

Unfortunately, there is no formula you can apply that will guarantee a win on any slot site. It purely comes down to luck, so be wary of anyone who tells you otherwise. 


What Progressive Jackpots Are Available on These Sites?

Most new slot sites usually offer a variety of different progressive jackpots, which give you the chance to win much bigger prizes. You should keep in mind though, that coin sizes tend to be limited, so games with progressive jackpots won’t always be available to everyone.
