What will you play next?
NetEnt is one slot game developer that thrives on changing up its themes and styles, but Double Stacks is a leap in the other direction. Its aesthetics look back to the candy-coloured casino games of old, with bubblegum colours and stylized fruit decking the reels. But even as it makes for a great retro callback, the Double Stacks casino game manages to be an interesting slot with unique and original gameplay.
Our review takes you through a comparison of some of the top features, which NetEnt online casinos carry this game along with our thoughts on how this game compares to other NetEnt slots.
Best features on Double Stacks slot
- Double-stack your symbols: Double Stacks takes its name from an interesting gameplay feature where symbols on the reel stack together for bigger winnings.
- Dozens of free spins: Win as many as 30 free spins at once, and retrigger up to 30 free spins again.
- Accessible and fun: Double Stacks has bonus features that are equally entertaining and easy to understand, making for a slot that you can quickly jump right into.
How to play Double Stacks slot for free or real money
You can play Double Stacks for free on our website or on a regulated casino that offers demo play, but you’ll need to sign up for a casino to play for real money. Either way, though, the gameplay remains the same. Double Stacks is a 5×3, 10 pay-line slot with a marginally above-average RTP of 96.10%, where you can set your bet from $0.10 to $200.
Once you choose your ideal bet amount, you can play manually or set the game to automatically execute up to 1,000 spins within custom parameters. You can set precise dollar amounts to make the game stop auto-spins after winning a certain amount, losing a certain amount, or triggering free slot games.
Overall, the basic gameplay and interface are average or above average, with some good quality-of-life features that many of NetEnt’s competitors still aren’t including.
Double Stacks graphics and design
Double Stacks visuals are a well-executed take on classic physical casino slots, with colours that pop and a warm, inviting look. It manages to be a bit kitschy and retro without going overboard, which makes for a game that classic slots fans will love and anyone can enjoy. Whether you’re thinking back fondly on slot games of the past or have more of a mind to create new memories, you’re sure to appreciate Double Stacks’ detailed, colourful look.

How Double Stacks’ bonus features work
Double Stacks’ landmark bonus feature is stacking, which occurs in normal gameplay as well as free spins. When all the symbols on a reel are the same, they become double-stacked and count as two when calculating winning combinations.
During free spins, the highest-value symbols also become stacked, not to mention that wilds become prevalent on the reels. Despite the fact that the game is only a 5×3 slot, it’s possible to connect 10 high-value symbols and win up to 1,000x on a single pay-line.
As for free spins, you earn them when scatter symbols land on the reels. During normal gameplay, the number of free spins you can win are:
- Three scatters: Five free spins
- Four scatters: 15 free spins
- Five scatters: 30 free spins
All of this applies to retriggering free spins during the bonus game. However, free spins also let you earn an extra two free spins when two scatters land on the reels.
Where to find the Double Stacks slot game online
While we offer unlimited free play on our website, you’ll have to check out Rivers Online Casino or FanDuel Casino to play for real money. Each of these online casinos can provide a safe place to bet, but they also have unique benefits to offer, such as FanDuel’s weekly promotions or BetMGM’s expansive collection of slot games.

Final thoughts on Double Stacks by NetEnt
Double Stacks is a great homage to the old days of casino fruit machines, with generous free spins and an interesting double-stacks mechanic to keep gameplay fresh. The visuals have the right vibrant, colourful look to really sell the theme and avoid the pitfall of feeling like every other fruit-themed slot.
We believe that the game deserves a strong 8/10 and recommend you give it a try.
