In the slot universe, bells usually signal dinner time or a wedding. However, our latest review of Mystery Kingdom: Mystery Bells slot machine turns these expectations on their head. Here, bells have far surpassed calling you to the table; they’re summoning you to a horror show where every chime could mean a fortune or a curse.
The 3×4 grid is the epitome of a gothic novel: a shadowy forest, an imposing castle, and an atmosphere thick with suspense. Luckily, the betting range is far from eerie, with a Wazdan standard of €0.10 to €10000.
And while the base game might seem as empty as a ghost town, with not a single pay symbol in sight – there’s a method to this madness. Your mission? Trigger the Hold The Jackpot Bonus Game, because that’s where the treasure lies. So, sharpen your sword, steady your nerves, and prepare to ring in a new slot review.

Game Features
Let’s start with the basics. Cash Collector Symbols gather the values of Cash and Cash Infinity symbols, amplifying your bounty with multipliers up to x20.
Meanwhile, Mystery Symbols add an element of surprise, transforming into any bonus symbol to potentially increase your fortunes, except for Cash Infinity, of course.
Cash Infinity Symbols are your beacon in the base game, sticking to the reels until they pay out at the end of the next bonus round. So, they’re not just some idle decorations; landing these on the middle row boosts your chances of triggering the Hold The Jackpot game, potentially illuminating your path with prizes between 5x and 10x your stake.
Cash Infinity Symbols are cute, sure but let’s not beat around the bush. The Hold The Jackpot Bonus Game is the heart of this slot. Land 4 bonus symbols on the middle row, and you’re granted a pick from the Mystery Bells before the game even begins. These bells could potentially jingle all the way to a 750x Grand Jackpot, offering a spine-tingling start to the feature.
Upon triggering the Bonus Game, the reels are filled with Mystery Bell symbols, each harbouring one of four jackpot prizes or leaving you with empty hands.
The excitement is in the reveal—a single choice that could end with a chime of victory. Once your selection is made, the feature proceeds with three respins, and the pursuit of filling all 12 positions with bonus symbols begins. True success means a grand win of 750x your stake.
