150 Free Spins Bonuses in the UK 2026

Yeti Casino is our pick for the best 150 free spins bonus without a deposit. However, it is only 23 free spins with 77 bonus spins, as getting 150 free spins is nearly impossible. Betway gives the full 150 spins, but you'll need to deposit £10 first.

All casinos on this page have been tested by our experts. We review not just the number of spins but also how to get them, which games they apply to, wagering requirements, RTP, volatility, and withdrawal speed. This ensures you see offers that are genuinely valuable for UK players.

Our Picks for the Top 150 Free Spins Casinos

As truly large, free no-deposit spin offers have become rare in the UK, so has finding 150 free spins casinos. Our team put in the effort to pick up some big offers that are still available. Whether you're after wager-free spins or deposit bonus spins, these casinos have offers that we know will bring real value to your game.

1. Yeti Casino - 77 No-Wagering Spins With No Winning Caps

We found Yeti Casino's welcome bonus genuinely rewarding, because the 77 bonus spins on the first deposit are wager-free and have no withdrawal limit. In addition, new players get 23 no-deposit free spins, with a reasonable 10x wagering requirement.

Our experts tested the welcome offers hands-on, and you can read their experience in the Yeti Casino review.

While it doesn't match a 150 free spins headline, we believe that the combination of no-deposit and bonus spins with fair, non-restrictive terms makes it a strong offer for UK players.

2. Betway - No Wagering, No Fuss, Just 150 Spins

Betway gives new players 150 spins with no wagering requirements, but you need to deposit £10 to claim them. That's why we don't call them free spins, but bonus spins instead.

See how our experts test the spins on all eligible slots and verify the terms in our Betway casino review.

What we really like is that this bonus comes with no wagering requirements, so any winnings are paid straight to your account as cash.

3. Casino and Friends - 150 Spins with a Taste of Pragmatic Play's Best

Casino and Friends also gives new players 150 bonus spins, but unlike Betway, these spins come with a £20 deposit, wagering requirements, and can only be used on the Big Bass Splash slot.

We still think that if you're willing to meet the 10x wagering requirement, this welcome offer is a generous way to explore one of Pragmatic Play's most popular slots.

We dive deeper into the site in our Casino and Friends review. From our perspective, the lack of withdrawal caps is always a good advantage when playing with any type of bonus.

4. MrQ - Free Spins and No-Wagering Spins for Casual Players

We have included MrQ in our recommendations for its unique, player-friendly bonus offer with no wagering or cashout limits. Instead of having 150 spins, MrQ gives you 5 free spins followed by up to 300 wager-free bonus spins.

The bonus spins are unlocked by depositing and spending £10 per day, which also explains why this offer sits lower on our list due to the multiple deposits required.

Read our team's full breakdown in the MrQ Casino review, where we explain how the no-wagering bonuses work in practice and highlight one of MrQ's biggest strengths: withdrawals that can land in your account in under an hour.

5. Betfred - Adjustable Bet Size for Spins

We picked Betfred as the last thanks to its adjustable bonus spins offer. This means that by depositing £10, you can get up to Up to 200 bonus spins if you want to play with the standard 10p bet size. You can also increase the bet by taking fewer spins in total.

This is a very unique concept and something you don't find at practically any other UK casino. We loved how it gives you the power to choose how you want to play.

For extra icing on the cake, the spins have a 0x wagering requirement and no withdrawal limits, so you can immediately cash out everything. In our Betfred Casino review, you can find the full list of slots you can play with these spins.

Our Rating Methodology

Our practical testing is a crucial part of the rating process and includes claiming free/bonus spins, checking wagering requirements, verifying withdrawal rules, and playing eligible games ourselves.

Beyond the spins themselves, we look closely at the bonus terms. We check how easy the offer is to activate, how clearly the rules are explained, and whether any limits affect winnings from bonus play.

Do the Spins Require a Deposit?

One of the first things we check at is whether a deposit is required for the spins. We want to find no-deposit spins, like those at Yeti Casino, as they really are the best for testing the site without putting any money in.

Deposit offers, such as Betway's 150 spins, usually provide higher number of spins but require a deposit of £5-£30. This is one of our most important considerations, as it helps players know what to expect before signing up.

How Difficult Is The Wagering?

Wagering requirements significantly affect the bonus's real value. We look for bonuses with the lowest possible wagering, with zero being the best.

Betway and MrQ score highly here thanks to their no-wagering spins. Casino and Friends require winnings to be wagered before withdrawal, which lowers the overall rating despite offering a high number of bonus spins.

How Much You Can Cash Out?

The most important factor in bonus win withdrawals is whether the winnings are capped or paid out in full. Casinos with no withdrawal limits on bonus winnings, such as Betway and MrQ, receive a higher rating from us than those with restrictions.

We always highlight win caps because the withdrawal terms directly affect how much winnings players can realistically cash out.

Different Types of 150 Free Spins Bonuses

Free spins bonuses come in many forms and are available for both new and old customers. Some are genuinely free, and others require a deposit (we call these bonus spins, since they are not free).

Below are the main types of spin bonuses you'll come across, with our recommendations on which type of players they are best for.

Popular 150 Free Spin Slots

Many free spin offers are tied to specific slots. We've selected these games because they're widely available at the casinos on this page and are known for features that make bonus spins more rewarding.

Big Bass Bonanza

Big Bass Bonanza is a favourite for spins offers thanks to its gameplay features such as multipliers, wilds, and free spins can make each spin more exciting and increase the chances of bigger wins.

• Special features: Retriggerable free spins and cash multipliers, which can boost potential winnings
• Volatility: Medium - balanced mix of small frequent wins and occasional bigger wins
• RTP: 96.71% indicates that, in the long run, this slot returns a fair proportion of wagers to players

We have many expert recommendations on where to play Big Bass Bonanza, and Yeti Casino is one of them, offering 23 free spins on the slot.

Book of Dead

Book of Dead is an evergreen classic slot with features simple enough for beginners to grasp, yet packed with enough action for demanding players. The high volatility in this slot makes it pay out less frequently but can deliver huge wins,

• Special features: Expanding symbols and free spin retriggers can lead to massive payouts
• Volatility: High - expect long dry stretches and potentially bigger infrequent wins
• RTP: 96.21% means that players can expect decent returns over time

Our team recommends checking out the best Book of Dead UK sites if you enjoy high-risk, high-reward gameplay and want to maximise the potential of free spins, or simply just enjoy this legendary slot.

Fishin' Frenzy

Fishin' Frenzy is a whole series of slots that includes popular titles like The Big Catch and Even Bigger Catch. These different versions make it a versatile option for bonus spin promotions. As a low-volatility slot, you can expert smaller, but regular payouts.

• Special features: Multiplier bonus rounds for more action and potential winnings
• Volatility: Medium - provides a mix of smaller regular wins with occasional bigger payouts
• RTP: 96.12% potentially brings some nice wins along the way

Among our team members, those who have enjoyed this slot the most are those seeking steady gameplay and frequent wins. Fishin' Frenzy makes a bonus like 150 spins last longer and offers nice variability across its series of games.

150 Spins Compared to Smaller Offers

Large free spin offers, such as 150 spins, are increasingly rare in the UK casino market. While you get a lot in a single bonus, smaller spin offers, such as 10 or 20 free spins, can be more flexible. With a small bonus, you can explore different casinos, games, and promotions without committing to just one site. In other words, less can sometimes be more.

Large Bonus Vs. Small

10 Free Spins

10 free spins are perfect for players who want to test casinos or games without committing any money. From an expert point of view, even a small batch of spins can reveal a lot about a casino's overall performance, game variety, and bonus terms before you deposit.

10 free spins no deposit are one of our favourites, and you can still easily find them in the UK.

20 Free Spins

20 free spins are even better, offering a bit more playtime and, of course, more chances for potential wins. We always enjoy 20 spins without a deposit, as they give us more room to test the casino with the same low risk as other small spins offers. That said, the game selection can be more limited, and these offers aren't always available.

Despite all the changes in the UK bonus market, many 20 spins deals are still easy to find.

Safety Matters Even With Free Bonuses

Free spins and bonuses might seem risk-free, but they still involve gambling. We want to remind you that responsible gambling is important with free offers just as much as with real money. That's why we only list UK-licensed casinos, clearly explain bonus rules, and suggest that players set limits early.

You should always take free spins as entertainment, not a way to earn money, and stop if gambling stops being fun. If gambling feels overwhelming, support is available through free, confidential services like GambleAware.
