In the Shadow of the Castle
Malta-based slot provider Wazdan is behind the Mystery Kingdom Mystery Bells Halloween Edition online slot. Wazdan is one of the industry’s top developers with a huge catalog of slots.
The Mystery Kingdom Mystery Bells Halloween Edition slot machine is a horror-themed slot set in the grounds of a creepy haunted castle. This castle can be seen looming in the background, along with skulls and cobwebs. The slot doesn’t use standard symbols, but it does have cash, cash infinity and jackpot symbols.
Scary Spins and Prizes
Betting options in the Mystery Kingdom Mystery Bells Halloween Edition online slot range from a minimum of 0.2 to a maximum of 10,000.
The Hold the Jackpot bonus is activated by landing four bonus symbols in the middle row of the four reels.
You are given three respins at the start of the bonus game. Bonus symbols will stick to reels, and your respins will reset for each symbol you land.
Cash symbols carry a value of between 1x and 5x. Cash infinity symbols carry values of between 5x and 10x. If cash infinitys trigger the feature, they will stay locked in place for the duration of the bonus.
Collector symbols accumulate values of cash and cash infinity symbols and then multiply the total by between 1x and 20x. This total is paid out at the end of the feature, which happens when you run out of spins or fill the reels with bonus symbols.
Jump Scare Jackpots
Jackpot symbols can also appear during the bonus. These can award the 10x, 20x and 50x mini, minor and major jackpots. The 750x grand jackpot can be won by filling the reels with bonus symbols.
The Mystery Kingdom Mystery Bells Halloween Edition slot machine has high volatility and a 96.2% RTP.
As the slot has no standard symbols, there is no pay table included in this review.
Check out the Dracula slot machine and the Creepy Carnival slot machine to enjoy more horror-themed slots.
Conclusion
This slot is unique in that it does not use regular symbols. This is a bit of a downside and limits the slot features available in the game. However, the Hold the Jackpot bonus game is well-designed and enjoyable to play. You can play Mystery Kingdom Mystery Bells Halloween Edition for free here at VegasSlotsOnline.
