Mystery Stacks Deluxe Slot Information

The game’s design is based on a classic casino theme with familiar symbols such as fruits, 7s, and BAR Symbols. You get a glimpse of an actual casino floor in the background of this slot. The neon lights and the frame surrounding the grid give you a feeling of playing a real slot game in Las Vegas. The American city is famous for its wide range of casinos and slot games and has been a role model for casinos worldwide. The reels of this game are in the middle of the screen, with the Bonus Buy Feature positioned on top. The remaining buttons are all placed below the reels, including the Bet size and Spin buttons. You can play Mystery Stacks Deluxe on all mobile devices, desktops, and notepads. You create a winning combination by landing 3 or more of the same symbol types on adjacent reels starting at the leftmost reel.

The lower-paying symbols are red cherries, a lemon, an orange, and a blueberry. Landing 5 of the same symbol type pays between 2X and 4X. The higher-paying symbols are a watermelon, BAR, 2 BARS, 3 BARS, and a Golden Bell. Landing 5 of the same symbol type pays between 10X and 30X.

Free Spins

Wild Symbol

The Wild Symbol substitutes all symbols except the Scatter Symbol and the Golden Mystery Token and helps you create winning combinations.

In-Game Bonus Wheel

3 or more Scatter Symbols will trigger this game’s Free Spin Feature and get you 10 Free to start with. The In-Game Bonus Wheel is instantly triggered by landing 5 Scatter Symbols during the Base Game. Landing 4 Scatter Symbols Symbols gives you a 50% chance, and landing 3 Scatter Symbols gives you a random chance of activating the In-Game Bonus Wheel.

During this feature, you are awarded cash prizes proportional to your bet with the chance of winning up to 1000X or 10 additional Free Spins.

Golden Mystery Tokens

This feature is randomly activated during the Base Game. A cluster of Golden Mystery Tokens lands on the screen and flips up to 3 times, revealing matching symbols with every flip. This feature always comes in clusters of more than 1, and the Big Mystery Token is 3X3 and allows full-screen wins of mega stacks.

Free Spins

If you land 3 or more Scatter Symbols, the Free Spins feature will be activated. You are then welcomed with 10 free spins and this feature cannot be retriggered. You’ll have a chance to trigger the Bonus Wheel at the same time as the Free Spins, thereby getting 20 Free Spins to start the feature, but the Bonus Wheel can not be triggered during the Free Spins. During the Free Spins, the Walking and Multiplying Wilds are active and add Wild Symbols to the grid.  

Walking and Multiplying Wilds

This special symbol is only available during the Free Spins and consists of three different versions of the Wild Symbol:

Wild Symbol with an arrow up = replaces the symbol above it with an additional Wild Symbol.

Wild Symbol with an arrow down = replaces the symbol below it with an additional Wild Symbol.

Wild Symbol with arrows both up and down = replaces the symbols below and above it with additional Wild Symbols.

Bonus Buy

If you want to take advantage of the Free Spins feature immediately, you can use the bonus buy option. You pay 70X the bet and then receive 10 Free Spins.

Mystery Stacks Deluxe Conclusion

Mystery Stacks Deluxe provides a classic slot experience that reminds you of Las Vegas. This is the second edition of the Mystery Stacks series from Silverback Gaming, and this deluxe version has some improvements compared to the previous game. Still, the provider has kept the graphics and the setup of 5X3 and 10 paylines. The graphics and theme create a perfect atmosphere for playing slots, and just like in the previous game, you’ll have the opportunity to activate the Free Spins immediately at a cost of 70X if you don’t have the patience to trigger the Free Spins with 3 or more Scatter Symbols. The Bonus Game is the key element of all slot games, and Myster Stacks Deluxe provides excellent features you will enjoy.

The RTP of the game is slightly below average and has a max win of 1000X; numbers we would like to be higher even though the max win has been doubled in this version. The Multiplying Wilds and The Golden Mystery Tokens have great potential to generate sudden big wins during the spins. The In-Game Bonus Wheel is only active during the Base Game and will be guaranteed to be triggered by landing 5 Scatters, but there is also a chance to trigger the feature with 4 or 3 Scatters. This allows you to trigger the Bonus Wheel and the Free Spins simultaneously and get a total of 20 Free Spins, which is a great bonus and requires some luck. Overall, this game offers excellent graphics with a solid theme and an upgraded version of the Mystery Stacks series. The Walking and Multiplying Wilds and the exciting Free Spin feature are great upgrades to this game, and this casino-themed slot is going to be cherished by all the nostalgic fans who are ready to start playing.

Mystery Stacks Deluxe is an upgraded version of a popular slot game with new Free Spins and Multiplying Wilds features!
