What Are Existing Players Bonuses?

What Are Existing Players Bonuses

Existing player bonuses are casino promotions you receive when you are already a member of a specific UK casino. They are rare compared to welcome bonuses tailored for new customers. However, they might have higher values or have more lenient casino bonus terms.

Some gambling sites offer existing players bonuses for loyal customers or even those who haven’t been active in a while. Each website decides when to provide these types of promotions and what conditions you should meet to be eligible.

Some considerations are needed before you engage in this article because bonuses for existing players are used to keep the player loyal. Still, multiple UK casinos have two pillars of rewarding frequent customers. The first tool to do so is bonuses for registered customers, but VIP schemes make the second pillar.

You must understand that VIP schemes are different from bonuses for existing players because you must work to grab personal bonuses designed based on your playstyle. The most known VIP system is across Casino Reward gambling sites, where you have one VIP scheme across all sister casinos.

For example, suppose you’re a Yukon Gold, Grand Mondial Casino, or Zodiac Casino member. In that case, you will see that the VIP system is the same across all casinos, which is very professional and lucrative.

Existing players bonuses vs loyalty bonuses?

To be eligible for an existing player bonus, being signed for a while on an active account is enough. You don’t have to complete anything else to play with that offer. Loyalty bonuses require a history of constant sessions and, sometimes, a limit of spending that you have to get over. Loyalty bonuses are reserved for players who already are in a loyalty scheme at a certain level.

Another major difference comes from the frequency with which you can find them. Loyalty bonuses are planned and offered on a fixed scheme of spending while existing bonuses do not come constantly.

Best Casinos for Existing Players Bonuses

Our experts know that sometimes existing players are overlooked, and there are few promotions available for loyal gamblers. We tested the top online casinos in the UK, and we made a list of note-worthy reload bonuses.

MadSlots Casino – Best Existing Player Bonuses at a UK Casino

MadSlots Casino – Best Existing Player Bonuses at a UK Casino

Unlike many casinos focused solely on acquiring new players, we appreciated that MadSlots also rewards loyalty through ongoing promotions for existing users. These offers incentivize returning throughout the week, and come as a token of appreciation for those who are consistent.

At MadSlots, there are only several days of the week where you can get the bonuses. Mondays, Thursdays, and Sundays all feature deals on popular slots. While the bonuses vary in amount, they all provide free spins. Of all their existing player promotions, MadSlots’ Double Mad Thursday bonus stood out to us. You get 20 additional spins for every £10 you deposit, up to 200 free spins. The featured slot changes every week, but is always a top UK title.

Best of all, MadSlots attaches reasonable 30x wagering rates to these deals – lower than the competitors. Our only critique was the minimum £0.10 or £0.20 bet allowed to use the spins. However, this is the unfortunate norm across most casinos currently.


  • Several promotions throughout the week
  • Wagering requirements that are lower than 30x
  • The bonuses can be used on popular titles


  • You can only stake the minimum bet amount for each slot

Rhino.bet Casino – Best No Wagering Existing Player Bonus

Rhino.bet Casino – Best No Wagering Existing Player Bonus

The best part is that the existing player deals at Rhino.bet come with zero wagering requirements attached. Your bonus winnings go directly to your cash balance, and you can keep all the winnings with no risk of losing them while completing the wagering requirement. We highly recommend giving Rhino.bet a try for this reason alone.

Rhino.bet takes a unique approach to ongoing promotions, which we found intriguing. It focuses on flash deals versus permanent existing player offers. Randomly throughout the week, you will have to wager small amounts, usually around £10, on specified slots to unlock free spins bonuses. They do have one recurring promotion not dependent on flash incentives – Rhino Reels. For every £250 wagered, you receive 50 free spins without playthrough. You can use the spins on any of the eligible games listed, rather than being restricted to one title.

While hitting £250 in bets may seem high initially, this threshold will be reached eventually if you are loyal to the casino.


  • High number of 50 free spins for the Rhino Reels promotion
  • You are not restricted to one particular slot
  • The bonuses come with no wagering requirements


  • You must wager £250 to qualify for Rhino Reels’ 50 free spins

21LuckyBet Casino – Best Reload Deposit Match Bonus

21LuckyBet Casino – Best Reload Deposit Match Bonus

21LuckyBet offers a unique Sunday 20% deposit match reload bonus via promo code SUN. This promotion can be redeemed multiple times daily but only on Sundays.

On Sunday, apply code SUN, and add a deposit over £10. Your bankroll will benefit from an additional 20% instantly. We appreciate the lower-than-usual minimum deposit and ability to use the bonus on any game type without restrictions, including table games and live dealer titles.

However, the 50x wagering requirements are quite steep. Experienced players may clear these easily, but less seasoned gamblers will struggle with such a high wagering requirement. If the playthrough seems too demanding, you could always go for the no wagering bonus options, such as Rhino.bet’s bonuses.

Beyond the Sunday match, 21LuckyBet also provides cashback bonuses, free spins, and a multi-tiered loyalty program.


  • Rare deposit match reload bonus available on Sundays
  • Other existing player bonuses, including cashback and a VIP program
  • Reasonable minimum deposits for each bonus


  • High wagering requirements of around 50x bonus

PlayOjo Casino – Best for Daily Existing Player Promotions

PlayOjo Casino – Best for Daily Existing Player Promotions

PlayOjo takes a straightforward approach to ongoing promotions through their PlayOjo Kickers programme, which we found quite refreshing. Each day, existing players can instantly claim bonus cash or free spins with no wagering requirements attached.

These daily Kickers require mostly no deposit to claim and winnings are yours to keep. This is a rare treat in the UK gambling industry. Just check in daily and opt-in to receive that day’s reward. While bonus amounts are smaller, we think the ease of activation and lack of playthrough makes up for it.

Beyond Kickers, PlayOjo also runs special tournaments open to existing customers. Right now there is a live casino tournament awarding free spin bundles to the top players.

Between the everyday Kickers and changing tournaments, PlayOjo focuses on instant, accessible bonuses versus complex loyalty programs. If you appreciate simplicity and want to skip wagering hassles, be sure to grab your daily Kickers.


  • There are no wagering requirements on any of the bonuses
  • You can claim the PlayOjo Kickers daily
  • There are multiple types of bonuses available, free spins and bonus cash included


  • Every bonus is a surprise, and you don’t know ahead of time what you get

MrQ Casino – Best for Refer-a-Friend Existing Customer Bonuses

MrQ Casino – Best for Refer-a-Friend Existing Customer Bonuses

MrQ stands out for offering lucrative refer-a-friend bonuses – a rarity in the UK casino market. Just get a friend to sign up using your referral link and ask him to make a qualifying deposit. This way, you earn 10 spins, and your friend also gets to earn 10 free spins. While the number of spins may seem low, it adds up fast by referring multiple buddies. You can enjoy the spins on the popular slot game Fishin’ Frenzy.

On top of friend referral bonus, MrQ also lets players spin their Daily Roulette Drop wheel under the Promotions tab. This determines a random number of points each day, which can be then used to collect different bonus bundles.

MrQ focuses on engaging returning players. While referral programs are quite rare in the UK, we especially liked the daily wheel spin offer.


  • This bonus does not require any deposit on your part
  • The spins are available on Fishin’ Frenzy
  • There is no wagering required for the spin winnings


  • The number of spins is quite low, at only 10 spins

Free spins with no deposit are the most popular type of UK bonus, so naturally, they are offered to existing players as well. Casinos create free spins for existing players no deposit UK offers to existing customers, and offer them batches of spins on slot games. Usually, these batches start at 20 spins and go up to 100 or 200 spins in one offer.

There are 3 ways in which you can claim free spin bonuses for existing customers:

  1. Bookmark this page to see the casinos you’re signed up at and their new bonuses. We show you how to claim each individual bonus and our expert rating of it.
  2. You will find the new bonuses in the promotional materials the casino sends you via email or SMS if you’ve agreed to receive such information on your account.
  3. Casino representatives contact you via live chat and give you the bonus on your account. Even though we have seen this happen a few times, such cases are rare.

Otherwise, claiming is much simpler if you’re already signed up. Just pick the bonus while logged in to your account, activate it with a code (when needed), and you can start playing.

How We Select Existing Customer Deposit Bonuses

Our selection criteria are rigorous because our central core of doing professional gambling is based on the principle of responsible gaming. With this in mind, you must know that we invest many hours looking at one casino with existing player bonuses. This happens because we encompass every aspect an online casino must have, like solid security measures for irresponsible gambling, a fair bonus policy, the number of games, and other features.

Selecting existing customer deposit bonuses involves categorising over 120 casinos with similar offers. After that, we started to cut the undesirable casinos where bonus practices aren’t fair for the UK audience. You will see what remains in our main list, but ultimately, you choose the best overall in the first comparison table.

The first criteria for ranking the best existing customer deposit bonus is how easy it is to claim such an offer; the second feature we seek is to be understandable for every type of punter. If there’s a complex, unclear policy, we will not suggest it.

On top of that, we look for those existing player bonuses that will expand your gameplay without you making high investment efforts. We want a pleasant experience where you spend little from your account. Even if you see that at Leo Vegas, the Fat Stacks Miami can be activated with a minimum of £20 and you consider this amount high, at KingCasinoBonus, we consider the two poles of player, high-rollers and average depositors.

Why Trust Our List?

To trust us blindly is not what we want from you. Our trustworthiness level is decided by those UK punters who read our articles, and the number is quite impressive.

One of our senior authorsVlad George Nita, managed to give a thorough technical analysis of the casinos that offer bonuses for existing customers. We will not just recommend a bonus that we never tested.

Our selection process is complex, and it’s the simulation of your future steps if you decide to join a casino we recommend. In 7+ years, we’ve developed a technique that bound the UK punter’s opinion with mathematical analysis systems like machine learning and reviews of the site audit documents. We ensure that the next casino that you will visit will offer you a high-quality betting experience.

How We Research No Deposit Bonus Codes for Existing Players UK

How We Research No Deposit Bonus Codes for Existing Players UK

At KingCasinoBonus.uk, we extensively test and review no deposit bonus codes for existing players at online casinos. We have a meticulous step-by-step process, as described below.

Trying the Bonuses First-Hand

Our team goes through creating real money accounts and becoming customers at each casino. We regularly check our accounts with the casino, at least once a month, to stay updated on the available deals for existing players.

To gain insight into the casino’s offerings, we actively deposit money and place bets, striving to advance through the VIP tiers and unlock casino bonus codes. This hands-on approach allows us to experience the platform just like any other user, giving us a comprehensive understanding of the casino’s bonuses, games, and overall functionality.

Additionally, our consistent engagement with the platform earns us existing player bonuses. We keep our site updated with any new no-deposit bonus codes that may arise while at a casino.

Analyzing Key Terms and Conditions

After qualifying for current player offers, we carefully review important details such as wagering rates, game contributions, bet limits, and expiration dates. We recognise that bonus fine print can be confusing due to its complex terms and conditions, so we aim to simplify any unclear regulations for you.

As part of our tasks, we constantly compare numerous casinos so we have a solid understanding of industry norms and standard practices. This allows us to locate deals with the best terms and assess if a bonus is appropriate for the general public or targeted at specific categories of gamblers.

We highlight incentives with shorter playtime requirements, broader game eligibility, extended validity periods, and significant bet limits. Furthermore, we rigorously read the tiny language to find restrictive provisions, which we instantly post on our website.

Trying to Get Positive Outcomes

Occasionally, a bonus might seem promising, but you may not gain anything if you don’t follow all the proper steps. That’s why we have testers within our team who go through the claiming process and attempt to meet the wagering requirements.

Even for experienced players, meeting these requirements can be challenging. Plus, no deposit bonuses for existing players often come with higher wagering demands, making it challenging to withdraw any winnings.

While we always follow specific steps to meet wagering requirements, sometimes it’s impossible to cash out any funds. We share these findings in our website content.

Highlighting the Best

Using our experiences playing with real funds, we evaluate which no-deposit bonuses are worthwhile and which have too many rules or may deceive you. Only bonus codes with fair terms and a real possibility of succeeding make it onto our list of suggestions.

We strive not to recommend bonuses that are difficult to cash out. Even if you believe no deposit is required, dealing with these kinds of incentives may be unpleasant and complicated.

How to Claim Existing Customer Bonuses?

  1. Use our page to see what new offers we have. We refresh the bonuses listed every 14 days, and as soon as we receive news that a new bonus is available, we start our testing process.
  2. Make sure you only trust in UKGC casinos and click on links from viable sources. There are a lot of scams and phishing tries across the web.
  3. Do not stack bonuses while you have an existing player offer active, it might be considered bonus abuse, and you might lose all your winnings
  4. If you encounter any issues while playing, contact support right away so they can help you.
  5. Be responsible when engaging with casino bonuses: don’t chase losses, don’t spend too much time gambling and spend only what you can afford.

What to choose, debit cards or e-wallets?

  • Card payments are better if you deposit large sums.
  • Pay by Phone casinos are suited to infrequent players and low depositors.
  • Cash depositors have a way to pay with Paysafe.
  • E-wallet transfers are recommended if looking for an under-1-hour withdrawal casino.
  • Choose PayPal UK casinos for the largest cashout limit and payouts in less than 1 day.

Most of the time, when it comes to gambling, it is better to take the safe route. So, for existing player bonuses, popular services like Visa, Mastercard, or PayPal are the most useful. As far as we’ve seen through our analysis, only 4.5% of cases have any glitches or issues when using these payment methods.

On the speed feature, e-wallets and online services are still the top choices. Skrill, Neteller, Apple Pay and PayForIt are still the best. The transaction speed on these is, on average, 230% higher than bank cards. However, you need to read carefully each bonus description we provide. Sometimes, these e-wallets are incompatible with your bonus.

One trendy option is Pay By Phone if the offer requires a deposit under £30. UK players use it more frequently, and your deposit will be charged on your phone plan. Regardless of your payment, always be aware of the possibly hidden fees and the waiting times needed. Make sure to stick to your budget and play safe!
