Why Do Online Casinos Offer 100 Free Spins No Deposit Bonuses?

In this section, we delve further into the wide range of reasons why no deposit bonus casinos in 2025 offer the promo to British players. Here are the main three.

• Attract new players: The most common reason UK online casinos offer the 100 bonus spins offer is that it attracts new players. As it does not require you to deposit and you can win money, the bonus is very popular with players too!
• Game developer promotion: From time to time, game developers work in conjunction with online casinos to promote specific slots. For instance, Pragmatic Play may run the 100 spins bonus on its popular slot, Chilli Heat.
• A new/exclusive game: If an online casino has an exclusive title to their library, they may promote it with the 100 extra spins offer. This can also be the case if the slot has been added to the collection or if the slot is brand new.

Different Types of 100 Free Spins Offers You Can Claim

British players can claim many different types of 100 free spins casino bonuses. It could be a deposit or no deposit bonus, or even no wagering free spins offer. In the table below, we briefly outline all the main types of free spin offers you can claim.

How We Rate UK Online Casinos With Free 100 Spins No Deposit

Our in-house team uses a tried and tested formula to determine what makes great online casinos. We do a deep dive into each platform to save you the hassle. We assess eight crucial factors before making a recommendation, which we will explain in more detail below.

• Security and licence: Before recommending any casino site, we check whether the SSL certificate is valid. If so, all your personal and financial data is secure. Also, we read all the fine print at the bottom about where the site is licensed. We prefer ones from Curacao, the UK Gambling Commission and the Malta Gaming Authority.
• Games and software providers: We like to see a wide range of casino games offered, from progressive jackpots and slots to table games, instant wins and live dealer games. When a site has both a casino and a sportsbook, this also scores high marks. Top software developers should supply titles for the best possible experience such as Quickspin, NetEnt and Novomatic.
• Bonuses and promotions: Our experts work tirelessly to find you the best casino bonus in the UK. We assess the quality of the promotions as well as the frequency. We also check whether the terms are fair such as wagering requirements and game contributions. Besides deposit and no deposit offers, we also compare special promotions such as tournaments, daily free spins, and VIP programs.
• Payment options: Before rating a casino site, we research the payments accepted. We prefer a wide range such as debit cards, e-wallets, e-vouchers, bank transfers and cryptocurrencies. All deposits should be instant, and when it comes to getting your winnings, the faster, the better. We even read the small print to double-check whether you’ll pay any fees.
• Mobile gameplay: Many British players love playing casino games on the go, so we ensure sites are optimised for mobile. If a platform has a dedicated app for iOS, Android, and Windows, it always scores highly in our eyes. If not, it’s also good as long as the website is optimised for mobile devices. Functionality is important, too, so you can deposit, withdraw, and play games on the go!
• Customer support: When you need customer support, there should be a wide range of channels to get in touch. The minimum we look for is two, being email and some form of live chat. When a site offers more such as social media and phone support, it’s better. Agents should be well-trained to deal with any issues and response time should be fast.
• Special perks: When ranking an online casino, we always see whether the platform offers anything extra. We are talking about VIP-level service, loyalty programmes and competitions. Access should be to all players, from beginners to high rollers and the terms should be fair. When a site goes the extra mile, it’s often a sign of a great online casino.
• Responsible gambling: Here at Slotozilla, we take responsible gambling very seriously. Therefore, we check whether casino sites offer UK players plenty of safer gambling tools and support if needed. We analyse the third-party links offered and whether you can set deposit limits, take time off, and self-exclude. We prefer you to be able to do these things yourself rather than contacting customer support.

Terms and Conditions to Take Into Account With 100 No Deposit Free Spins

As with the vast majority of bonuses you can claim at online casinos, there will be terms you must meet before you can withdraw real money. We cover the key six factors and give you a description of each one.

• Wagering requirements (WR): Always part of any no deposit free spins promotions and are stated as a number. They mean how many times you must bet the bonus money before you can withdraw. For example, if you get 50 free spins at 10p each and the WR is 40x, you must place wagers (win or lose) of at least £200 to cash out.
• Maximum win: A maximum win amount is the most you can withdraw in real money from the promo. This can be anywhere from £20 – £500, depending on the free spins bonus. If you win more money than the stated amount, it will be forfeited when you withdraw. This is most common with any no-deposit free spins bonuses.
• Time limits: Once you’ve claimed any type of free spins bonus, it will have an expiration date. In our time, we’ve seen this anywhere between 24 hours – 30 days. Once the free spins are expired you will not be able to use them. We advise you to use any free spins you have immediately so you do not forget about them at a later date.
• Payment method: With some free spin bonuses that require a deposit, certain payment methods will be disqualified. This is often prepaid or e-wallets like Skrill and Neteller. Also, with some no-deposit free spins deals you may be required to register a valid payment option.
• Game restrictions: Often the spins will apply to a selected slot by the online casino, such as Starburst, Cleopatra or Book of Dead. However, you may get a choice from pre-selected slots or particular game developer slots such as Pragmatic Play, NetEnt or Red Tiger.
• Bonus code validity: To claim the free spins, with many online casinos you must input a valid bonus code. Make sure that it’s correct and case-sensitive. If not, you will not be able to claim the bonus.
