What Are 500 Bonus Spins?

500 Bonus Spins

500 bonus spins are a type of promotional offer where players receive 500 free spins to use on slot games. If you claim such offer, you get a chance to win without having to wager real money.

You can receive this bonus after making a deposit. No deposit 500 free spins are very rare on the UK market, but it all depends on the bonus rules outlined by the casino you use.

A 500 bonus spin offer can come as a standalone welcome bonus or as part of an existing matched deposit bonus.

🚨 Keep in Mind: There are often several restrictions attached to these bonuses, such as wagering limits or eligible games, so the extra spins may work only on one game or a set of slots as specified by the casino.

How We Rank Our Recommended Bonus Offers

Below, we’ve outlined some 4 key factors we consider when ranking 500 bonus spin casinos based on their offers:

  1. Licencing
  2. Bonus terms & conditions
  3. Deposit/withdrawal support
  4. User-friendliness & overall optimisation


Licensing indicates trustworthiness and reliability when it comes to gambling. Thus, it’s one of the first factors we look out for when assembling a list of recommendations for you.

Since we focus on the UK market, we ensure that our listed casinos have official licenses from the UK Gambling Commission.

We also seek licenses from reputable bodies, like the Malta Gaming Authority and Curacao eGaming Authority, for offshore platforms.

You can find the licensing information of an online casino at the bottom of the homepage.

Bonus Terms & Conditions

The terms and conditions attached to a bonus can determine whether it’s worth claiming or not. Before making our recommendations, we ensure that all bonus terms and conditions are fair for users.

These terms range from the wagering requirements to the bonus validity, minimum deposit amount, maximum bonus conversion limits, etc.

Deposit/Withdrawal Support

Payment is important to fund your account and cash out earnings, so there’s a need to look for platforms with reliable banking options.

For UK users, some of the popular payment options are e-wallets like Neteller, Skrill, and Payz. You can also find traditional methods like bank cards and wire transfers available.

When a casino offers only a limited number of banking methods, it may not be suitable for all players, as everyone has their preferred way of making payment.


Our team at CasinoSherlock know the importance of user-friendliness in online gambling. As a result, we often add the usability factor as a guide to help shortlist only the best online casinos.

We prefer platforms with top-notch mobile optimisation, site editions and dedicated mobile (Android & iOS) apps. To ensure smoothness, we also test these sites on different devices with both new and old hardware to ensure they can run on any of your devices.

✅ High-value bonuses like 500 bonus spins allow players to explore new slots without fear of running out of bonus credit.

The higher the value of a bonus, the higher its bonus conversion limits. Most 500 bonus spin offers come with maximum conversion limits reaching between £200 to £500 or more.

If you opt for a 500 bonus spins casino, you will encounter one potential drawback.

👎 The wagering requirements of most high-reward bonus spins are often demanding, making it challenging to beat these requirements.

How to Claim Bonus Spins

Follow 3 easy steps to activate up to 500 bonus spins in UK casinos:

  1. Create a casino account
  2. Make a deposit
  3. Activate bonus spins

Create a Casino Account

The first step to claiming a 500 bonus spin offer is to create an account with a casino providing the incentive.

✅ Casino Pro Tip: To become eligible for any bonus, you also have to ensure you verify your account.

You can conduct research using our guide or save yourself stress by selecting from our recommended list of 500 bonus spins casinos.

Make a Deposit

You are required to make a deposit to activate most 500 extra spins bonus offers. The only exception is in the case where the offer is a no deposit bonus, which is very rare when it comes to such high-value offers as 500 free spins.

To make a casino deposit, visit the menu area of your casino dashboard, select the “Deposit” tab and choose your preferred payment method. Keep in mind the min deposit required to to claim the offer.

Activate Bonus Spins

You automatically activate your bonus spins when you fund your account with the minimum deposit specified by the casino.

However, in some casinos, you are required to input a promo code or head to the Mega Reel or Wheel of Fortune. In such cases, the casino reveals the reward once you spin the Mega Reel for 500 bonus spins.

Once you activate and claim your bonus spins, you can use them on all eligible slots and stand a chance to win real money if you land a winning combination.

👉 Don’t Forget: Before claiming any 500 extra spins bonus, you should go through the bonus terms and conditions to ensure they are fair.

Types of 500 Bonus Spins

Here are 5 most popular forms of 500 extra spin bonuses on gambling sites:

  1. 500 bonus spins sign-up bonus
  2. 500 free spins no deposit
  3. 500 extra spins daily bonus
  4. 500 bonus spins mega reel reward
  5. 500 bonus spins no wagering bonus

500 Bonus Spins Sign-up Bonus

In UK, 500 bonus spins on sign up are casino offers that allow players to receive 500 spins for registering and verifying a new account and making a valid deposit using a supported payment method.

Most standard bonus spins come as sign-up offers or welcome rewards for new players. These bonuses are available in almost every UK casino, but there are some slight differences regarding game restrictions.

Keep in mind that these offers are game-specific in some casinos, which means you can only use them on a specified set of eligible games.

500 Free Spins No Deposit

As the name implies, 500 free spins are spin offers you receive in a casino without having to make any deposit. If you come across a no deposit bonus, be aware as they come with higher wagering requirements and additional bonus rules.

However, high number of free spins with no deposit required are rare in the UK. We’ve mostly come across 5, 10, and 20 free spins deals.

500 Extra Spins Daily Bonus

Extra spins daily bonuses are rewards which provide a high number of bonus spins spread across a specific duration of time.

As such, this offer can give you 500 extra spins as a daily offer of 100 bonus spins for five days or even at a smaller split for more days.

These daily bonus offers also come with wagering requirements. However, they often feature moderate terms compared to no-deposit offers.

500 Bonus Spins Mega Reel Reward

The Mega Reel bonus spin reward allows you to win up to 500 bonus spins on the Mega Reel, all with a minimum deposit of £10 on a supported UK casino. This is one of the prevalent forms of bonus spins available in British online casinos.

❗ Keep in Mind: Unlike the other forms of bonus spins, Mega Reel rewards are unpredictable. Your bonus worth remains unknown until you spin the wheel.

There are several rewards you can receive from the Mega Reel. Some are 500 bonus spins on Fluffy Favourites, bonus spins on Starburst or other top slots, Amazon voucher cards, etc.

Once you receive a Mega Reel bonus reward, the casino instantly adds the offer to your bonus balance. However, you need to meet the wagering requirements before requesting a withdrawal.

500 Bonus Spins No Wagering Bonus

These promotions allow players to receive up to 500 bonus spins subject to no wagering requirements. If you claim this type of casino offer, you keep whatever you win using your 500 bonus spins, and it’s one of the most profitable forms of bonus spins.

However, these types of extra spins are rare in online casinos, so they are quite difficult to come by.

Also, be aware of any limiting bonus T&Cs, like high wagering requirements or max winning caps, that can significantly reduce the value of the bonus.

Common Terms & Conditions of 500 Bonus Spin Rewards

Common Terms and Conditions of 500 Bonus Spin Rewards

Just like with other casino bonuses, 500 bonus spins have terms and conditions governing how to use them. Below, we’ve outlined 6 key T&Cs, which you’ll find attached to casino bonus spins:

  1. Wagering requirements
  2. Bonus validity
  3. Max bonus conversion
  4. Game restrictions
  5. Minimum deposit
  6. Player eligibility

Wagering Requirements

A wagering requirement represents the number of times you have to wager the bonus before being eligible to request a withdrawal.

💡 Did You Know: Most UK casino bonuses feature around 30x wagering requirements, which means you have to wager your bonus amount up to 30 times before you can request a withdrawal.

Bonus Validity

Bonus validity represents the lifespan of a bonus spin offer. If you receive a bonus spin, the casino expects you to activate and use the offer within a specific period.

This period often ranges from 7 to 30 days for most 500 extra spin bonuses. Once a bonus reaches its validity limit, it expires and becomes completely void.

Max Bonus Conversion

A maximum bonus conversion limit indicates the highest amount of money you can earn from the reward. It’s a crucial bonus term that lets you know when to stop and request a withdrawal.

The excess funds become void if you accumulate any amount above the maximum conversion rate.

Game Restrictions

Game restrictions determine what games you can use with your bonus spins. Even if 500 bonus spins are available in your casino account, you may not be able to play your favourite slot games if there are game restrictions on the bonus.

Sometimes, this offer can come as 500 free spins reward, usable on only one eligible game. In this case, you cannot utilise your free rewards on other games.

Minimum Deposit

A minimum deposit signifies the least amount needed to activate a bonus.

✅ Did you know? On average, most UK casinos allow players to activate bonus spins with a minimum deposit of £10.

This amount can be slightly higher or even lower, depending on the casino. This bonus condition does not apply when bonus spins come as a no deposit offer.

Player Eligibility

Player eligibility for casino bonuses refers to the specific criteria that players must meet to qualify for and claim bonuses offered by online casinos. These criteria vary depending on the casino and the specific bonus in question.

For example, in some casinos, bonus spins are designed for new players, while some sites provide similar offers exclusively for existing players.

Top Slots to Play With 500 Bonus Spins

Here are 4 most popular slots that stand out as the top choices for both bonus spins and real money wagers:

  1. Starburst
  2. Fluffy Favourites
  3. Sweet Bonanza
  4. Rainbow Riches


Starburst is one of the most renowned NetEnt slots, developed back in 2012. It has remained one of the most-played games among gamblers ever since. With a slot RTP of 96.09%, Starburst provides the potential for some good winnings.

It offers unique experience and broad support for bonus offers. So, it’s usually available as a supported game for 500 bonus spins.

Fluffy Favourites

Fluffy Favourites is one of the slots often available on the Mega Reel and also as a Wheel of Fortune prize for bonus spins. You can get game-specific offers of 500 bonus spins on Fluffy Favourites and other smaller offers.

The standard Fluffy Favourites slot is a fun game with a colourful animal theme, providing an entertaining atmosphere. The game supports many bonuses and is one of the classic slots from Eyecon.

Sweet Bonanza

Sweet Bonanza is a more modern slot with an awesome candy-themed design launched by Pragmatic Play in 2019. This game has a great bonus spin support in online casinos.

It has an RTP rate of 96.49%, which is above the average for online slots. Also, the maximum payout of Sweet Bonanza reaches as high as 21,100x your bet, so a 500 bonus spin offer can result in huge winnings if you’re lucky enough.

Rainbow Riches

Rainbow Riches is one of the classic slots with Irish theme developed in 2006 by Light and Wonder (formerly Barcrest). It is still relevant in the gambling industry close to two decades later, and it works well with bonus spins.

It comes with several bonus features that allow you to maximise your overall winning potential and stand a chance of earning big from bonus spins.

Rainbow Riches is a medium to low volatility slot, so it’s easier to trigger a winning combination. This is great for bonus spins, as they help you win more often.

Below are 5 other slots that offer excellent gaming experiences with bonus spins.

Tips & Tricks For Maximising 500 Bonus Spins

Please keep in mind that there’s no proven trick for landing big wins with a 500 bonus spin offer. However, there are 3 essential tips that you can utilise to help improve your overall experience using bonuses:

  1. Bet wisely
  2. Understand wagering contributions
  3. Play low volatility slots

Bet Wisely

Bet only the amounts you can afford to lose and try to set strict rules for your gaming sessions. You can also utilise some responsible gambling tools to help cut your gaming sessions and limit your deposits.

Understand Wagering Contributions

Make sure to always find out wagering contributions or game restrictions attached to a bonus and understand this rule, as it’ll allow you to fulfil the bonus requirements quickly.

❗ Remember: Playing games with low wagering contributions will leave your wagering requirements almost the same.

In some casinos, it may also lead to disqualification if used wrongly. As a result, we advise that you always go for games with 100% wagering contributions.

Play Low Volatility Slots

Playing low volatility slots is one of the best tricks to maximise your 500 bonus spins offer. Slots with low volatility often trigger winning combos, so it is easier to land some winning hands with your bonus spins.

Of course, these slots offer small payouts. But, the consistency can allow you to accumulate some reasonable amounts over a long period.

Are 500 Bonus Spins Worth It?

Overall, the only significant downside to using a 500 spin bonus we found are the high wagering requirements. They offer a great experience for players looking to try online casinos without using their own money.

They extend your playtime and allow you to explore new games. Remember to check the terms and conditions for wagering requirements and game restrictions.

With the right approach, 500 bonus spins can make your online casino experience even more exciting.

Don’t Forget to Prioritise Responsible Gambling

Gambling should be a form of entertainment at all times. While online casinos offer a lot of excitement and entertainment, it’s important to gamble within your means and never bet more than you can afford to lose.

It’s also important to recognise the signs of problem gambling and seek help if necessary.

Excessive gambling can lead to financial difficulties, addiction, and other negative consequences so it is important to be aware of the risks involved and the responsible gambling practices on the other hand.

A few guidelines to follow are:

  • Set monetary and time-bound limits
  • Gamble only the amounts you can afford to lose
  • Never chase your losses
  • Don’t gamble when upset, angry, depressed, or intoxicated
  • Take breaks in between games

🚫 Please note that in the UK, only individuals aged 18 and over are legally permitted to engage in gambling activities.

For help with a gambling problem, call the National Gambling Helpline on 0808 8020 133 or go to to be excluded from all UK-regulated gambling websites.
