Double Stacks is a five-reel, three-row, new online slot from prolific video slot machine design studio NetEnt. This slot brings together the perfect combination of modern, high-definition visual design and game features with classic fruit machine styles and symbols. Big bright symbols and pulsing background highlights on the reels make this one a real treat to play on both PC and at mobile phone casinos.
As the reels spin across the ten fixed pay lines on Double Stacks, you’ll see the classic fruit machine symbols like cherries, lemons, plums, diamonds, lucky sevens and bars. There are also, of course, wild and scatter symbols to spice things up as well as some interesting and not-so-conventional bonus features to help elevate your payouts. With the possibility to win 1000 times your original bet on any spin, there’s always the chance to add considerable bulk to your bankroll at any moment.
The player is given the opportunity to set the coin value and bet level — or coins to bet per pay line — they’d like to use on each spin. The minimum and maximum bet levels are one and ten respectively, while the coin value can be set anywhere from £.01 up to £2.00. That gives us a minimum bet of £.10 per spin and a maximum of £200.00.

Where to Play
No – Why Not Play?
- Although the 1000 times your bet payout is nothing to laugh at, if you want chances of winning something really big, there are slots with much higher maximums.
- Double Stacks is a high volatility slot machine. This means players will need sufficient bankroll to weather possibly severe ups and downs. Most players would also expect a higher maximum payout on a high volatility slot.
- Double Stacks offers a 96.1% return to player (RTP) rate which is ok, but there are slots with much higher RTP.
Double Stacks Slot Bonus Features
The Double Stacks slot offers three different bonus features, in addition to wild symbols, that can help out a ton on their own. When the three combine, though, there are chances for some truly colossal wins. Let’s take a look at how they work.
Maximum Payout Jackpots
There are four possible jackpots that can be won if all of the spaces on the reels stop on the same symbol. Each of the four top-paying symbols — which are the diamonds, sevens, bars, and bells — can stop stacked on the reels. When you get the same symbol stacked all the way across, you’ll win big.
Filling the reels with bells will get you 100 times your bet back. Bar symbols will pay you back 250 times your bet. When the lucky sevens appear all over the reels, you’ll get 500 times your bet. And finally, if you manage to fill the reels with diamonds, you’ll win a whopping 1000 times your bet.
Double Stacks Feature
During the regular game, it is possible for the four top-paying symbols to land stacked on the reels. When this happens, that symbol will double. For example, if you land three diamonds on one reel, they will double, and you’ll get two diamonds in each space on the reel.
When wins are counted, any doubled symbols count as two rather than one. Using the diamonds as an example again, if you get stacked diamonds on the first reel and another diamond on the second reel, the first reel will double, counting as two diamond symbols, and then match with the diamond on the second reel as if you had landed three diamonds.
Free Spins Feature
Free spins are triggered when three or more scatter symbols land on the reels during the base game. Three symbols will get you five free spins. Four scatters reward you with fifteen, and, if you land five, you’ll get an extremely generous 30 free spins.
During free spins, in addition to the possibility of the four most valuable symbols appearing stacked, wild symbols can also appear stacked on the reels.
It is also possible to re-trigger free spins with the following combinations of scatter symbols:
- 2 Scatters = 2 Free spins
- 3 Scatters = 5 Free spins
- 4 Scatters = 15 Free spins
- 5 Scatters = 30 Free spins
Our Verdict
The Double Stacks slot does a great job of mixing old school and modern slot design styles. Most designs that try to replicate the old fruit machine style go a bit too far and end up making the player feel like they’re sitting in front of a completely outdated machine. Double Stacks maintains a modern feel while still delivering a real tribute to those classic slots, and you won’t feel like you’re missing out on anything.
The maximum pay out doesn’t quite match up with some of the competition out there, but the generous bonus features make up for it somewhat. The double stack feature definitely adds an interesting twist to normal gameplay. Throw in the possibility of 30, 60, or more free spins, and there’s a chance for some big winning combinations.
Overall, I’d give the Double Stacks slot a good recommendation. It should do a good job of holding the attention of fans of both older and newer slots, and the betting options will fit with just about any type of bankroll and gambling style. Double Stacks is certainly worth a look, and I’d highly encourage you to look for it at your favourite NetEnt casino.
