Double Stacks is the latest slot from the Swedish game maker NetEnt, and this is a slot we have been looking forward to for a while. Premium symbols with double stacks means that it’s possible to win up to 1000x the bet in a single spin, and in the exciting bonus round the wilds are stacked as well. In this Double Stacks slot review we will cover everything this colourful NetEnt game has to offer.
Double Stacks introduction and info
When you first open Double Stacks, it might remind you of a few other NetEnt slots such as Twin Spin or Dazzle Me. The slot has a striking design that features classic slot symbols such as melons, cherries, sevens and bars. At the top of the reels you will see a list of prizes for each premium symbol, and that is how much you’ll win if you hit a full screen of each of them. We will come back to this special feature a bit later in the review.
Double Stacks has a classic video slot setup with 5 reels, 3 rows and 10 paylines. It features the four low paying symbols cherries, lemons, melons and plums, and the four high paying symbols bells, bars, sevens and diamonds. It also has a wild that substitutes all other symbols, and a scatter that activates the bonus game. Double Stacks has an RTP of 96.10%, and as we mentioned earlier it’s possible to win up to 1000x in a single spin – by getting a full screen of stacked diamonds.

Slot design and features
Retro looking video slots are all the rage these days, and lately NetEnt has gone back to the casino roots by creating a few slots that have simplistic yet beautiful designs and graphics. Double Stacks is a very colourful slot that has flashing lights and quick animations, and it’s nearly impossible to keep the eyes off the reels as you watch them roll by.
NetEnt are known for creating slots that have innovative features and twists. The unique feature of this slot is that the four premium symbols can land stacked and cover a full reel, and when that happens it counts as a double symbol. For example, a stacked symbol of bells on the first reel and a normal bell on the second reel will count as a win of three of a kind, even though there are only two symbols in a row. As you play you are always looking for those juicy fullscreens, as hitting one will trigger the following jackpot sized wins compared to your bet stake: bells 100x, bars 250x, sevens 500x, and diamonds 1000x.
Double Stacks bonus game
When three or more scatter symbols land anywhere on the reels, the bonus game will be activated. You will get at least 10 bonus spins, but it’s possible to get up to 30 spins by hitting five scatters. The bonus looks similar to the main game, but there is one important difference: in the bonus games, the wilds can appear as stacked reels, making it much easier to hit winning combinations and full screens of the premium symbols. The bonus can also be retriggered, and just two scatters in the bonus game will give you two extra spins.
After playing Double Stacks for an extended period of time, our conclusion is that this is a slot that fits nicely into NetEnt’s already big portfolio. It’s a simple but powerful game that plays and looks great on both desktop and mobile, and it can reward players with some awesome wins. If you enjoy innovative slots with medium volatility and flashy retro designs, you should give Double Stack a go.
