Where Can I Play Mystery Kingdom: Mystery Bells for Real Money?

If you’re looking for options to play this online slot for real money, we suggest the following casinos below. Each site has been reviewed by our team in order to make sure you’ll be playing at the best casinos that feature the Mystery Kingdom: Mystery Bells.

Pro Tips

I could hardly offer tips on how to play Mystery Kingdom: Mystery Bells without having any experience playing the game. That’s why you can trust Johnslots though. All of our experts fully test each release before publishing a review to get a handle on the game and what it has to offer. So, what’s the deal?

First off, as Mystery Kingdom: Mystery Bells has an adjustable volatility setup, you should factor that into your playstyle and available bankroll. I suggest opting for the medium setting, as it offers a good balance between risk and reward.

Next, although many players like to mix up their bets when playing slots, it’s important to stick to one bet size to make the best use of the Cash Infinity symbols. While these will remain on the reels until you trigger the Hold the Jackpot bonus, changing your bet size will cause them to disappear.

Finally, remember that gambling should be fun. There’s plenty of reason to get excited about playing Wazdan’s new online slot but stick to a limit. You can use a range of responsible gambling tools at all UK online casinos to keep track of your spending, and I strongly recommend you do so.

Mystery Kingdom: Mystery Bells Bonus Features

Mystery Kingdom: Mystery Bells isn’t your traditional type of online slot. While nearly all other modern slot machines include features to complement the general gameplay, this particular slot is all about bonuses and jackpots. When I say that, I’m referring to the fact that there are no regular paytable symbols, meaning you won’t get any standard reel payouts when playing.

Still, what is on offer is a range of novel mechanics that combine to deliver some great payouts. Features such as Cash Infinity and Hold the Jackpot can work together to enhance the game’s potential, while the One Click to the Grand Jackpot feature can instantly award the 750x top prize.


As Mystery Kingdom: Mystery Bells does not utilise a traditional paytable, there is no Wild symbol.

Scatter Symbol

More often than not, if you’re looking to trigger a slot’s bonus round, you’ll need the help of the Scatter symbol. Again though, this is where Mystery Kingdom: Mystery Bells slightly differs from the norm. Instead of a single Scatter, the game comes with several Bonus symbols, all of which work towards activating the game’s main feature.

There is one special symbol that you’ll want to watch out for in the base game though – the Cash Infinity symbol. Any time it lands in any position, it will stick to the reels until you next trigger the Hold the Jackpot feature. Therefore, if it lands on the middle row, you’ll have a better chance to hit the main feature.

Free Spins / Respins

So, on to the main attraction. As I’ve already mentioned, Mystery Kingdom: Mystery Bells is all about bonuses, and the game’s ultimate draw is the Hold the Jackpot bonus round.

To activate the feature, you will first need to land 4 bonus symbols across the middle row during the base game – they don’t have to match, it can be any of them. Once you’ve done so, the triggering symbols will lock into place and you’ll earn 3 Respins. You’ll then get a chance to instantly win the game’s top prize courtesy of the One Click to the Grand Jackpot feature.

Before the Respins begin, Mystery Bell symbols fill all of the empty positions surrounding the middle row. The only thing you’ll need to do is choose one and click it to potentially discover a prize. It will either reveal an empty position or one of four jackpots – Mini, Minor, Major or Grand. If you successfully locate the Grand prize, the bonus will instantly end and you’ll scoop 750x your bet. If you reveal anything else, you’ll move on to the Respins.

You’ll start with 3 Respins, during which either bonus symbols or empty reel positions land. Whenever any type of bonus symbol locks into place, the Respin counter resets to 3. There are 5 types of bonus symbols which trigger various effects, which I’ve outlined below.

  • Cash symbol: These are basic symbols that award prizes ranging from 1x-5x your bet.
  • Jackpot symbol: Mini, Minor and Major Jackpot symbols can randomly appear during any Respin, awarding 10x, 20x or 50x your bet, respectively. Pleasingly, you can win multiple jackpots of the same type during the feature.
  • Mystery symbol: This will transform into any other bonus symbol at the end of the feature, with the exception of the Cash Infinity symbol.
  • Mystery Jackpot symbol: Once the respin counter reaches zero, it will reveal a guaranteed Mini, Minor or Major Jackpot symbol.
  • Collector symbol: Upon landing, the Collector symbol accumulates the value from all Cash and Cash Infinity symbols and randomly multiplies them by 1x-20x.

Finally, if your luck is in and you manage to fill all 12 positions on the reels during the bonus, you’ll instantly win the Grand Jackpot prize worth 750x your bet.

RTP & Volatility of Mystery Kingdom: Mystery Bells

There’s a lot of information to consider when choosing the right online slot to play; special features, the game’s maximum payout and its overall feel are huge factors that determine whether it appeals to certain players. However, many experienced slot players, including myself, also look at key stats such as the Return To Player (RTP) rate and volatility. These are important elements that dictate the overall gameplay. The RTP refers to your theoretical returns over the long term, while the game’s volatility dictates the expected frequency and value of its payouts. Low volatility slots tend to produce smaller wins more often, while high volatility slots tend to favour infrequent and larger wins.

With that in mind, Mystery Kingdom: Mystery Bells clocks in at a 96.13% RTP, comparing favourably to the 96% average for modern releases. As for its volatility, Wazdan has included three adjustable settings – low, medium and high. That means you have much greater control over the gameplay, allowing you to swap between them at your leisure, which I felt was a nice touch.

Finally, as Mystery Kingdom: Mystery Bells has undergone a rigorous testing process before release, you won’t need to worry about the safety and fairness of the game. Still, if you’re keen to try it out, make sure to only play at fully licensed online casinos, ideally those that are UKGC or MGA-licensed as they have proven their commitment to the most stringent regulatory requirements.

Mystery Kingdom: Mystery Bells on Mobile

Knowing that many players prefer to play on the go, Wazdan has developed its latest release with the smaller screen firmly in mind. That means whether you’re out and about or simply like to play a few spins from the comfort of your sofa, you can enjoy all that Mystery Kingdom: Mystery Bells on your chosen handheld device.

It’s fully optimised for all market-leading devices, including smartphones and tablets supporting iOS, Android, or Windows software. Therefore, as long as you have a stable internet connection, you’ll have no trouble playing at your favourite mobile casino!

Personally, I gave it a go on a tablet and I was extremely pleased with how smoothly the game ran. The loading times were quick, the spins seamless and all of the visuals were crisp.

Pros & Cons of Mystery Kingdom: Mystery Bells

No online slot is perfect. After all, much of a game’s appeal comes down to what you enjoy. Still, on the whole, Mystery Kingdom: Mystery Bells hits the mark in a lot of areas, even if it does have a few potential flaws.

First of all, I enjoyed the straightforward nature of the gameplay. While there are several elements to consider during the bonus, the main goal is simple: land four symbols in the middle row. I also liked how the Cash Infinity symbols work. It isn’t often that an online slot comes with a feature that inherently boosts your chances of triggering a bonus, well, without it costing you more per spin anyway. Plus, when you trigger the Hold the Jackpot bonus, the sense of anticipation is palpable. When any spin can deliver multiple jackpots and multiplied payouts, there’s always a reason to get excited.

As for potential drawbacks, the lack of a traditional free spins mode could potentially hinder the game’s appeal, while the 750x maximum win seems somewhat miserly. Nevertheless, Mystery Kingdom: Mystery Bells clearly has more going for it than against it, at least in this humble online slot fan’s opinion.


So, what are my overall thoughts about Mystery Kingdom: Mystery Bells? In all honesty, I was perhaps guilty of judging the game before actually playing it, but when I saw there was no free spins bonus and only a 750x max win, I wasn’t overly enthusiastic about what it had to offer. However, after testing the game for a few hundred spins, I’m pleased to say that it greatly exceeded my expectations.

After reconciling the fact there are no base game payouts, I began to see how each spin was more of a gateway to the main bonus, and each Cash Infinity symbol that landed only increased my levels of excitement. Then, as soon as I triggered the bonus, it dawned on me that I could instantly hit the Grand Jackpot – I didn’t, but it didn’t stop me from hoping. Yes, the actual bonus itself may be simple, but it works well and can generate some reasonable payouts. Okay, so you won’t be in line for life-changing wins, but the game is fun and you can still walk away with a tidy profit. So, overall, Mystery Kingdom: Mystery Bells gets my solid recommendation and two thumbs up. Give it a go for yourselves to see if you can hit the Grand Jackpot!

Simply reach out to me via the contact form, mention Mystery Kingdom: Kingdom Bells in the title, and I will try to get back to you ASAP.

No, this online slot doesn’t include a traditional free spins bonus. Instead, the main attraction is the Hold the Jackpot respin feature, which offers four fixed jackpot prizes, special win multipliers and instant cash rewards. You can also instantly win the game’s maximum payout by revealing the Grand Jackpot symbol before the feature even begins!

Ultimately, it depends on how you like to play slots. If you’re more of a conservative spinner, you’ll be better off opting for the low volatility setting as it’s more likely to produce regular wins. However, bettors who prefer the chance to hit bigger payouts might want to switch to high volatility. Still, I feel as though the medium setting is the best option. It offers a nice mixture of good wins at a reasonable hit rate, keeping your bankroll ticking over as you hunt for the main bonus.

Given Wazdan’s position within the industry, you’ll have no trouble finding the provider’s latest release at a host of top UK casinos. I recommend sites such as LeoVegas and Dream Vegas, as not only do they keep up-to-date with all of the latest casino games, but they also provide new and existing customers with a great welcome bonus and a variety of other generous casino bonuses and promotions!

Yes, most UK casinos let you test out online slots for free in demo mode to get a feel for the game before you play for real money. In that case, you won’t need to deposit any amount, but, you won’t be able to win cash on the demo version of the slot machine. It’s a great way to experience all of the available features with no risk of losing funds.
