Go Back to Basics – Retro Style

The neon lights are buzzing and the music is playing, which could only mean one thing – the Mystery Stacks online slot. This retro-themed video-slot takes the term “back to basics” to a whole new level with the jukebox-styled grid and bright symbols. 

The symbols are similar to those of your traditional fruit slot, with the bell being the highest-paying one. Land five of these to walk away with a payout of up to 50,000 credits. Next come the triple, double, and single BAR icons. 

The Mystery Stacks slot machine’s lower paying symbols include fruit which pay in the following order: watermelon, plum, orange, lemon, and cherry.

Set Your Stake

Get the retro party started by setting your first Mystery Stacks slot machine bet. Take your pick from values ranging between 0.10 and 1,000.00. Such a wide selection proves that this game is one for every kind of roller. Your stake will be spread over the 10 paylines found in this 5x3 game. Winning paylines can start from anywhere within the grid.

We’ve put together a table with the symbol payouts based on a maximum bet of 1,000.00 below. We recommend checking out the Mystery Stacks online slot’s paytable to see the numbers corresponding to a lower stake.

Unravel the Mystery

While the Mystery Stacks online slot may not have an abundance of special features, the ones it has could send you home with quite the win. You’ll see a coin fall across the reels. Its size determines its feature.

The smaller one (the same size as a normal symbol), the Mystery Coin, flips at the end of the spin, revealing a mystery symbol. The larger one, the Mega Coin, has the same function but it guarantees you a win.

The symbols these Mystery Stacks slot machine coins reveal will always be the same for increased chances of completing a winning combination.

Keep the Vintage Theme

If you enjoyed spinning retro style, then check out the Disco 70s slot by Portomaso Gaming. Play over 25 paylines for a prize of up to 1,000 credits when collecting enough disco balls. Get to the bonus game to try your luck with a x3 win multiplier.

If it’s more paylines you’re after, make a beeline for the Twin Spin slot by NetEnt. Take advantage of the 243 ways to win and enjoy the Twin Reel Feature, where each spin starts with identical reels that are linked together for more chances to win.

Get Your Groove On
