Mystery Kingdom: Mystery Bells

Mystery Kingdom™: Mystery Bells Slot Features

There are no regular pay symbols in the base game, and the bonus symbols you land will only pay in the bonus round. You need 4 bonus symbols of any type on the middle row to trigger the Hold The Jackpot Bonus Game, and this also gives you one pick that may reveal the Grand Jackpot.

You can land Cash Infinity symbols in the base game, and these become sticky until they pay at the end of your next bonus round. Cash Infinity symbols come with cash prizes between 5x and 10x your stake, and if they appear on the middle row your Hold The Jackpot Bonus Game chances are increased.

All empty positions are filled with Mystery Bell symbols after the Hold The Jackpot Bonus Game has been triggered. You get exactly one chance to reveal 1 of the 4 jackpot prizes. Click on your chosen Mystery Bell, and you can win 10x, 20x, 50x, or 750x your stake from the Mini, Minor, Major, or Grand Jackpots, respectively. You are not guaranteed to win anything, however, as you can also reveal a blank.

All the triggering bonus symbols are sticky on a 12 reel positions grid, but the Mystery Bells are removed once you’ve made your choice. You get 3 respins for starters, and only blanks or new bonus symbols may land. Each spin where at least one bonus symbol is added to your collection of sticky symbols resets the respins tally to 3 again.

Regular cash prize symbols come with values between 1x and 5x your stake, and you can also land multiple instances of the Mini, Minor, and Major Jackpot symbols. The Cash Collector symbol accumulates the value from both Cash and Cash Infinity symbols, and the sum total is then boosted by a random multiplier between x1 and x20.

You can also land Mystery Symbols, and these will turn into a random bonus symbol (except for the Cash Infinity symbol). The Jackpot Mystery Symbol will turn into 1 of the 3 smaller jackpots already mentioned, and both mystery symbol types are revealed at the end of the feature. If you fill all 12 positions with bonus symbols, you win the 750x Grand Jackpot. This is the game’s win cap, so all your other winnings will not be paid if that happens. Otherwise, they are paid as the feature ends.

Review Summary

The game has created what amounts to almost their own parallel universe in the world of online slots, with their highly recognizable style and equally highly customizable gaming experience. It’s fun to mix things up and try different volatility settings, and if you’re picky about spin pace the experience is a dream come true. They also have an eye for detail, and if you look closely, you can see tiny bats circle the spooky Count Dracula castle in the backdrop.

We have seen a base game with no possibility of winnings before from this developer, and it’s not as shocking this time. The good news is that you tend to get the Hold The Jackpot Bonus Game on a regular basis, and you can max out the spin pace to reduce the base game time even more. The feature comes with more than enough special symbols to keep things interesting, but only to the tune of 750x your stake. Mystery Kingdom™: Mystery Bells is well worth checking out in our view, and we recommend the low or medium volatility setting for this release.
