Free Deposit Spins on New Slots This Week
Barbarossa DoubleMax
Peter & Sons is flashing the features on the highly volatile Barbarossa DoubleMax, a slot that pairs a slick pirate adventure theme with the DoubleMax mechanic from license partner Yggdrasil. This game uses a familiar 5 reels and 3 rows grid with the 243 ways to win engine. The backdrop is a tropical setting with a cove for ships and treasure.
You can start playing from £0.20 or boost up to £50 per spin, while the 96.2% RTP offers average payout rates with high volatility. The base game features cascading reels, removing winning symbols, dropping new ones, and keeping wins flowing.
The DoubleMax feature is the main attraction and doubles a multiplier after each cascade, with no limit to the potential number of drops/multipliers. There is also a free spins bonus offering between 7 and 13 freebies, again with the potential for unlimited re-triggers.
Barbarossa DoubleMax is now available on Play Jango Casino and claim a generous deposit match bonus alongside free spins.
Le Zeus
Hacksaw Gaming’s Le Zeus brings a mythical concept with a cheeky vibe by adding Smokey the raccoon into an ancient Greek setting dressed as Zeus. The game has 6 reels, 5 rows, and an uncommon 19 paylines. With an RTP of 96.26% and medium volatility, the slot has a solid balance between regular wins and possible big payouts.
In fact, you can choose to spin the reels from £0.10 to £100, and the biggest potential win is a generous 20,000x your stake. Wild symbols are red hot in this game. Not only will the sub for other symbols to build winning lines, but they also pay out up to 200x. A Mystery Reveal symbol can turn into high-paying symbols, Mystery Reels with payouts up to 500x, or wild.
Other symbols include Multiplying Clovers and Pots of Gold. Scatter symbols open one of the three bonus rounds: sticky Mystery symbols in Bolt & Run, a progressive Mystery Meter in Myth-Taken Identity, or stacked Mystery reels and removed low-pays in Gods Just Wanna Have Fun.
Try Le Zeus for yourself at Hippodrome Casino with a £100 welcome bonus with 100 free spins.

Free Spins on Sign Up
Free spins on registration are a common and appealing bonus offered by many online casinos.
Simply create an account, and you’ll receive a set number of free spins to use on selected slot games. The number varies—some sites give 20, others 50 or more—and they’re often linked to popular titles like Starburst.
These spins might be available instantly with no deposit required or triggered by your first deposit. Either way, they offer great value, especially when winnings are withdrawable.
Regular players also benefit, as many casinos feature ongoing free spins promotions. It’s always worth comparing offers and game selections before signing up.
Free Spins No Deposit
No deposit offers are the bread and butter of the gambling world. If you see a free spins slots offer with the promise of no deposit; grab it with both hands. You’ve got the chance to make your fortune, without spending any of your own money. Essentially, it’s at the risk of the betting site, and you don’t have to worry about anything. You will have to sign up and submit payment details (for future reference), but no money will be taken upon registering your account.
Again, the free spins bonus can vary from the bookies. For example, free spins UK deals may offer 20 with one bookmaker, and 50 the next, but check the terms before settling for one.
Free Spins No Deposit Offers
Free Spins No Wagering Requirements
More often than not, most promotions involve terms and conditions. These terms, generally, include wagering requirements that require you to jump through a huge number of hoops and conditions before you see any winnings. However, free spins casino deals with no wagering requirements mean exactly that – you can turn the winnings into actual cash without doing anything.
Generally, the likes of free spins slots deals require you to wager your bonus funds and any winnings made more than 10x to withdraw. However, those without wagering requirements mean the winnings are automatically credited to your account, usually within one hour. Those winnings can then be withdrawn or used again on other games to make even more money.
Play OJO ‘the fair casino’ is one example of a bookmaker offering the deal. According to OJO, there are no hidden terms and wagering; all customers get 50 free spins on first deposit with no wagering. This deal is exclusively available on their House of Doom slot game. Similarly, BGO casino offers 10 free spins with absolutely no deposit and no wagering requirements. It’s another free spins no deposit keep what you win deal.
Free Spins Keep What You Win
Another common free spins offer is the keep what you win. As mentioned above, betting and casino promotions, typically, come with a number of terms and conditions. Walk on hot coals, sing to the queen and wager your bonus funds 40x. While these are by no means hard to follow, they can be frustrating for new customers – particularly if you have to meet the rollover requirements within a certain amount of days. If you don’t meet them, your funds will likely be revoked, and that’s the last you’ll see of them.
However, many bookmakers are offering customers the chance to keep what they win, and not worry about any rollovers before turning them into actual, physical cash. There are many bookmakers you can choose from when looking at these deals, such as PlayOJO, Wink Casino, 888casino and more. Likewise, existing customers with bookmakers can enjoy this free spins slots offer. The likes of Sky Vegas reward customers weekly with Starburst free spins and more. You don’t even need a positive account to qualify.
What are Wagering Requirements?
As expected, all sign up casino bonuses do come with wagering requirements. These terms, generally, relate to the games available and the conditions you must meet to withdraw. Typically, most free spins no deposit required promos will have requirements that involve wagering the bonus funds a certain number of times to turn it into real cash.
William Hill Casino is one such brand that offers up to 50 free spins for all new and existing customers. A total of 10 spins are released per day, for five days, but you have to wager the winnings 40x to withdraw. While you do have to wager, this is, essentially, a free spins no deposit keep what you win. When you wager, those winnings are yours. Similarly, 777 casino offers a free spins no deposit bonus. All new customers will receive 77 free spins, with requirements to wager 30x before withdrawing. It’s also another case of keep what you win when you meet the easy-to-understand terms – you can’t say fairer than that.
How to Calculate the Wagering Requirement
Once you understand the basics of calculating wagering requirements, you will be able to check through all to find the best. For example, you register with a casino, and they offer 10 free spins. You win £20 and the wagering requirement is 10x the winnings, to calculate the wagering req.:
20X10=£200
In this instance, you multiply 20×10, which means you need to wager £200 on the slots to withdraw funds. This can be rolled out across all casino sites, so you know where you stand.
Free Spins Casino
Free spins casino offers are available for both new and existing customers. You tend to see more new casino free spins for those that sign up, rather than existing customers. Online casino free spins can be available for a range of games, all with different (and massive) jackpots. When looking for free spins casino deals, you need to compare online casinos alongside the free spins casino offers. Look for sites that offer the deal on a range of games, including their most popular. You should also have a look at how they treat their existing customers, and if they are rewards for those that regularly play.
Free Spins Slots
Free spins offers on slots are what you’ll find with most of these promotions. Mobile slots free spins are great for those that play on the go, as long as you get a good deal and impressive software. Online slots free spins are readily available with most bookies, often added to welcome packages to encourage you to play. One of the best options are the Wink Slots free spins, promising 30 free spins for all new players. Plus, there are 100s more games to choose from.
