Mystery Kingdom™: Mystery Bells offers dynamic gameplay that deviates from the norm, and its unique bonus features hold the promise of significant rewards. The absence of traditional paylines in the base game adds to the game’s mystique, with bonus symbols stealing the spotlight.

Other than a comprehensive explanation of said bonus feature, you’ll get a full scope, including game mechanics and rules, along with other features that’ll keep you glued to the screen. Stay tuned for our accompanying video review, where we explore this captivating slot even more. 

Is the Design of Mystery Kingdom™: Mystery Bells Royally Mysterious? 

The Mystery Kingdom™: Mystery Bells slot machine transports players to a foggy forest with a mystery castle in the background, conjuring a medieval atmosphere with skulls, spider webs, and swords. While you’re trying to collect your rewards, the dark color scheme, spooky sound effects, and ominous music score add to the horror theme. 

Unraveling the Mystery Kingdom™: Mystery Bells’s Mechanics

The slot offers an impressive 53 betting amounts, ranging from the minimum bet of 0.20 to a whopping 10,000. No calculation of coins per payline is necessary. Your total wager will be multiplied by bonus game winnings.

Mystery Kingdom paylines don’t exist. In the 4-reel, 3-row layout, the only way to win is by playing the bonus game. Drawing four bonus symbols in the middle row triggers the “Hold the Jackpot” bonus game with the opportunity to reach the Grand Jackpot feature.

The RTP of the slot is set at 96.13%, and the volatility level can be changed to suit the player. The slot falls into the category of above-average returns on investment games.

The degree of risk involved in playing the slot machine is referred to as volatility. It regulates how frequently and how much a slot machine pays out. Mystery Kingdom™: Mystery Bells’s volatility is adjustable, allowing players to select a high, medium, or low variance game mode based on risk tolerance.

Wazdan depicted this graphically—you may alter the variance by pressing the chili button next to the main spin button. Choose one pepper for sweet, two for hot, or three for volcanic volatility.

Gameplay Explained 

As said, the game has no regular paying symbols, which is quite unusual for online slots. The bonus symbols drop and pay only during the bonus round:

• Cash infinity symbols
• Mystery symbols
• Jackpot symbols

Next to the spin button, you’ll see an autoplay button. Looking like a classic play button, it will open a window offering standard and advanced autospin options. You can set the game to spin the reels automatically 10, 20, 30, 50, 70, 100, 500 or 1,000 times. You can also indicate when you want it to stop, such as:

• When you win a bonus feature;
• If a single win exceeds a certain threshold;
• If your balance increases by a specific amount;
• If your balance falls by a certain amount;
• On any win.

You can combine any of these five options or select all five.

The Bonus Bliss of Mystery Kingdom™: Mystery Bells

Cash infinity symbols that occur during the base game and remain in place until the Hold the Jackpot Bonus Game ends. These symbols can grant multipliers ranging from 5x to 10x the amount wagered. The cash infinity symbol in the center row increases the chance of activating the Hold The Jackpot Bonus Game, which features One Click to the Grand Jackpot.

Standard Bonus Feature

When you trigger the feature, up to eight empty reels are covered with mystery symbols. You choose one of them, which can transform into Mini, Minor, Major, or Grand jackpot icons or stay empty. 

At the beginning of the bonus game, you receive three spins. The bonus symbols stick to the reels until the conclusion of the free spins. With each bonus symbol hitting the grid, the spins reset to three again. 

Furthermore, the game includes collector symbols that collect all values from the cash symbols and cash infinity. The prize is the sum of their values unless you win the Grand Jackpot. If you draw the Grand Jackpot symbol, the game ends right there, and you receive a maximum 750x multiplier:

• Mini symbol gives a 10x multiplier
• Minor symbol grants a 20x multiplier
• Majori symbol rewards you with a 50x multiplier

The Mystery symbol can become any bonus symbol except the cash infinity symbols so that it can become the Mini, Minor, and Major Jackpot symbols. Mystery and Jackpot Mystery symbols reveal their value at the end of the feature.

Bonus Buy

If you don’t want to wait for the bonus to appear, don’t worry—you can just buy it. And the Kingdom will provide you with five options so it can fill the royal treasury:

1. The low bonus buy costs 50x the selected wager for one infinity symbol;
2. The standard will cost you 75x the bet, but you also get one mystery symbol along with a single infinity coin;
3. The high option will demand a payment of 100x the bet for two cash coins and one mystery symbol;
4. A 150x the bet extreme option doubles the high offer; you start with four infinity symbols, a mystery, and a jackpot mystery symbol;
5. Double extreme keeps the same amount of infinity coins but adds one more mystery symbol for the price of 300x the bet.

Gamble Feature

Players can activate the gamble function for a classic double-or-nothing game. They must predict the color of a spinning coin—red or green. If the player’s guess is correct, their earnings are doubled. If the guess is incorrect, the winnings are forfeited.
