Double Stacks Slots is an arcade style video slot from NetEnt.

Visually, you can compare the game to a classic fruit machines. There's cherries, melons, sevens and even a bar symbol.

Despite the retro style, you could not accuse this game of being out of date in the features department. This is one slot that offers stacks of serious fun.

Double Stacks Slots Special Features


Double Stacks Slot is a 10 payline slot with 5 game reels. Stacked symbols are the name of the game. And we're not just talking about stacks of symbols on the reels. Even the symbols themselves can come stacked. 

If a reel stops and all of the symbols are the same, then they will double into a stacked symbol. The four biggest paying symbols in the game can be stacked and will instantly double rewards. Even though this is not a jackpot game, the maximum payout for a max symbol win is displayed above the reels.

There is also a wild symbol that can appear in the base game. This star symbol will substitute for other symbols in a winning payline - but it cannot substitute the scatter symbol.

Double Stacks Free Spins


We also have a free spins feature, which activates with a certain number of scatter symbols. The minimum is 5 free spins for a 3 scatter match - but can increase to 30 free spins with a 5 scatter match. During free spins, the wild symbol can also become a stacked symbol.

And that's not all; spinning additional scatter symbols during the bonus will retrigger even more free games. In fact, you can reactivate 30 free spins if you hit another five scatter combo.

Double Stacks Slot RTP


The theoretical return to player on this slot is 96.10%, which is above average for a NetEnt casino slot. While we did compare the game to low variance slots like Starburst slots in the intro, the game is anything but low variance. 

Despite the arcade looks and feel, this is in fact a high variance slot game. This means that wins are scarce but are very valuable when they do occur. There is a maximum win of £200,000 available - which is achieved by 15 double stacked diamond symbols.
