Theme and General Gameplay
This slot was developed by Net Entertainment and is designed after the class 5-reel slots. Things have gotten a facelift though, and you’ll find 10 paylines, free spins, and stacked wilds among the diamonds and cherries. It’s one of several old-fashioned slots to receive an updated design in recent years.
Overall, Double Stacks feels luxurious, mellow, and like it’s fit for the modern high roller. The symbols themselves are bright and glowing, but they’re underscored by a deep purple background. The music is relaxing and gives off a bit of a retro feeling without sending you back to the 70s.

| Wild |
There are two special symbols that make an appearance in Double Stacks. These are the Scatter and Wild symbols. They are aptly named, as the symbols are actually the words themselves. If you land 3, 4, or 5 spins anywhere in a single spin, you’ll be awarded 5, 15, or 30 free spins respectively. These can be won indefinitely if you continue to land scatter spins during a free spin.
The wild symbol can appear at any time. However, it can only be double stacked during free spins. If you land a lucky combination of stacked symbols and wilds, you can win 1000x your bet on a single spin, for a maximum of $100,000.
Double the Action with Bonuses
The main feature of this slot is its double-stacking ability. Double stacking is only available for the four premium symbols (and the wilds, during free spins). Stacking allows multiple symbols of the same type to appear vertically in a row.
If you’re lucky enough to land a full stack of three, the number of that symbol on your board is counted as 6 – it’s doubled. If you wind up with 5 doubled symbols on a single payline, you’ll win big for creating 10 of a kind.

Variance, RTP and Tips/Strategy
This modernized slot has an RTP of 96.10%. If you were to theoretically gamble $100, you’ll likely win back at least $96.10 over time. This is a little lower than some slots, but it’s still decent enough to provide entertainment.
This low-to-medium variance game means that most of your wins won’t be excessively large. Even so, we found that landing some sort of win occurred every few spins and kept things interesting and exciting. If you want the most bang for your buck, consider placing higher bets for those times when double stacks do line up in your favor.
Conclusion – Let’s Welcome Classics to the 21st Century
There are lots of online slot games available these days. You can enjoy your favourite movie, video game, or holiday in gambling form – and that’s fantastic. Even so, it’s nice to take a step back once in a while and enjoy something a little simpler. There isn’t an abundance of bells and whistles, and the game isn’t swimming in bonuses.
That said, we thought the retro theme was executed perfectly. If you’re looking for a mellow way to enjoy your game time, this is a relaxing and fun option. What do you think? If you haven’t tried Double Stacks, give it a shot and let us know what you think in the comments.
