The Double Stacks ™ slot from NetEnt might look a lot like an old-fashioned fruity like the Fruit Shop slot, but it’s a cool little game with some decent features.
Stone the crows, Wombat fans, this slot randomly doubles certain symbols when they land, giving you better chances of scooping wins, so you can bring try and home the bacon!
Fair dinkum, this is the doppelgänger slot!
Let’s dive straight in…
Look and Feel
The Double Stacks slot has a classic fruity feel but it’s an upgraded version. I like the look of this game with its sharp clean graphics and brightly coloured icons.
It’s brighter than the Basketball Star slot and Dazzle Me put together! A simple game that does the job.

Game Play
Double Stacks slot has five reels, three rows and ten pay lines. Bets start at 0.10 and go all the way up to a max bet of 200.00 per spin in your local currency.
The symbols on the reels include melons, lemons, plums and cherries as your low-value symbols plus bells, bars, lucky sevens and diamonds which are the big ballers.
So very much like the Double Triple Chance slot except for one thing: landing five diamonds on a pay-line will pay out 4.5x your bet!
The wild icon in this slot is the gold star with WILD emblazoned across it, and it will do the usual job of substituting for all symbols on the reels (except for the scatters).
And speaking of which, the scatter in the Double Stacks slot is the glitzy disco ball icon. A nice touch NetEnt, very Studio 54!
Double Stacks Feature
Let’s take a look at where this game gets its name from. When matching symbols land on top of each other when the reels stop after a spin, the Double Stack feature is triggered.
The stacked symbols are doubled, with each single symbol counting as 2 -which means double the payout!
So say you managed to get five diamonds on a pay-line, this will amount to a chunky win of 1,000x of your original bet. You can’t say fairer than that!
Free Spins and Bonus Features
Land three, four or five scatters anywhere on the reels and you’ll scoop up five, fifteen or thirty free spins respectively.
During the bonus round, the spins can also be re-triggered by landing more of the Scatters.
Sadly there are no multipliers on offer, but the Wild symbol will appear stacked and double if it covers an entire reel. And don’t forget that the double stacks feature will be active on all standard icons too.
Play Double Stacks on Mobile
Do you prefer to spin the reels while you are out and about? Well, you’ll be pleased to hear that this game has been optimised for play on smaller screens. It’s the same game but in a dinky size.

This a great addition to NetEnt’s collection of innovative slots. Give it a whirl!
