Read on to find out if this online slot has what it takes to make it really stand out from the crowd?
Double Stacks is a 5 reel slot with 10 paylines and comes with Free Spins, Stacked Symbols, and a Double Stacks Feature.
Top Casinos for Double Stacks
The first feature to discuss is that the 4 highest paying symbols (Diamonds, 7s, Bars, Bells) appear stacked on the reels in the main game. Stacked symbols greatly boost your chances of landing a big win on the reels especially when you land a bunch of them together on one spin.
The obligatory Wild symbol is represented by a gold star with the word ‘Wild’ displayed inside. Like most Wild symbols, the main job of this symbol is to substitute for all other symbols apart from the Scatter to help form winning combinations on the reels.
Whenever a reel stops and all the stacked symbols on it are identical then all the symbols on the reel will double to count as two symbols instead of one. This is known as the Double Stacks feature. This makes it possible to land 10 of kind winning combinations. Manage to fill all 5 reels with identical double stacked symbols then you will win the maximum payout displayed beside the appropriate stacked symbol which is located just above the reels. If you are lucky enough to fill the reels with double Diamond symbols then you will take home the top prize of 1,000X your total bet!
The Scatter symbol is depicted by the word ‘Scatter’ surrounded by a pink and blueish circle. Land 3 or more of these symbols anywhere on the reels to activate the Free Spins feature. It goes without saying, the more Scatters you land then the more Free Spins you will receive. 3 Scatters awards 5 Free Spins, 4 will give you 15 Free Spins, and 5 Scatters will give you a nice set of 30 Free Spins. During this feature, Wild symbols will also appear on the reels as normal symbols or in stacks. This is a nice addition to this feature as it makes things super easy to fill the reels with just 1 specific symbol. It is also possible to retrigger Free Spins by landing additional Scatters during this feature. For example, getting 2, 3, 4, or 5 Scatters awards 2, 5, 15, or 30 extra Free Spins.

Theme and Graphics
The game has a real retro feel to it with an almost 80s colour scheme consisting of soft pinks, bright oranges, and radiant yellows. The reels feature a stylish purple design and the background of the game is a swirling reddish pink pattern. Symbols are wonderfully created and a nod to fruit machine games of the past. They consist of Diamonds, Bars, 7s, Bells, Cherries, Plums, Lemons, and Watermelons. The animations are superb as symbols dazzle and sparkle brightly when part of a winning combination on the reels. I especially like whenever you trigger the Free Spins feature, a smart intro video sequence will kick in.
The music is ambient and quite soothing with lots of soft techno sounds. It ties in really well with the classic fruit machine theme of the game.

Our Verdict on Double Stacks
This game comes from NetEnt and is quite a simple slot to play but also very enjoyable too. Double Stacks features cracking visuals, a hypnotic soundtrack, as well as a decent amount of features. Make no mistake, this game is all about the lucrative Stacked Symbols which make it nice and handy to fill the reels with the same matching symbol. The highlight of the game is the Free Spins feature which can take quite a few spins to trigger but is definitely worth your patience as the Wild becomes stacked here to really increase your chances of landing a massive payout cash prize. In terms of variance, I found this slot to be Medium so it won’t take you too long to see a profitable return on the reels.
