Mystery Stacks Deluxe Base Game

Mystery Stacks Deluxe Base Game and Features

Stripped back, straightforward, and lean are three ways to describe the gameplay on offer inside this medium-high volatile, 5-reel, 3-row release stuffed with iconography that is instantly synonymous with classic fruit machine play. Think BAR symbols, melons, grapes, and the like. Features are threadbare, but hopefully, the charming retro concept makes up for their notable absence.

In keeping with the vibe, the action is hosted on a jukebox plucked straight from the 80s dressed in rich licks of neon and plenty of sparkle. A congruent backing audio adds plenty of grooves to accompany your spinning, meanwhile.

Symbols are served by an assortment of stock fruit machine imagery: cherries, a lemon, an orange, a grape, and a melon offering wins up to 10x your bet for winning combinations of 5. Shelling out slightly higher rewards are a single BAR, a double BAR, a treble BAR, and a bell – the latter fetching wins equal to 50 times the stake when 5OAK wins form. A payout is achieved for landing identical symbols adjacently across the 10 paylines in play anywhere on the grid – breaking with old-school fruity tradition.

Mystery Stsacks Deluxe - Coins


While fruit is resplendent, Coins are the real star of the show inside Mystery Stacks. There are two types available: a Mystery Coin that flips when it shows up to reveal the same random symbol, while its more powerful sibling, the Mega Coin, ensures a win if it lands.

Don’t expect to find any Free Spins or other cutting-edge features in the offing here. Coins, the mystery kind, are just about all Mystery Stacks has to offer from a bonus standpoint, manifesting in a simplified gaming experience geared towards the more casual spinner as well as those looking to get their groove on rolling back the years.

Mystery Stacks Deluxe: Our Verdict

Well, that was certainly one of the shortest reviews we’ve put together in a while. Literally, a matter of seconds was all it took to absorb the game’s info section, which revealed an alarming lack of features with only Coins in two forms providing the vast bulk of the thrills.

If you’re reeling from the effects of a heavy Saturday night and yearning for some no-nonsense slot action while lying motionless on the couch, then great, Mystery Stacks Deluxe could be just the ticket, but if you’re one of the many more discerning casino fans eager for greater thrills and deeper complexity, you won’t find it in Mystery Stacks Deluxe.

The slot’s name is a bit of a misnomer, too. Not quite sure what is particularly Deluxe about the game. Sure, the production is grade A, but it’s questionable whether everything else – like the dearth of features and paltry 1,304x max win, is befitting of such a tag.

There are a multitude of vintage-styled slot releases on the market to satiate old-school gamblers, and Silverback Gaming has done little to upset the applecart with this spangly yet restrained release.
