Slot Review: Double Stacks by NetEnt

While NetEnt has made a name for itself as a highly-acclaimed slots developer, players have recently been disappointed by the company’s output of slots, citing low winning potential. Double Stacks, the developer’s newest slot, is therefore a refreshing release that can award up to 1000x on a single spin, and it also includes a Double Stacks and Free Spins feature.

Slot Specs

Double Stacks is a 5-reel, 3-row, 10-line video slot with a minimum bet of $.10 and a max bet of $200. You can earn up to 1000x your bet on each spin, which means that high rollers can hit a whopping $200,000 on one spin. As for the RTP, it’s within the acceptable range at 96.1%.

Visually, the slot looks like a rather typical fruit machine, but the reel symbols light up the screen and the soundtrack is fantastic. Lower-paying symbols include cherries, plums, lemons, and watermelons, while higher-paying symbols include 7’s, diamonds, a Bar sign, and a bell. The 4 higher-paying symbols are stacked on the reels and a full screen of diamonds will activate the highest possible win of 1000x your bet. There are also wilds and scatters, but these are not stacked.

Double Stacks

When a reel stops and all symbols are the same stacked symbol, the Double Stacks feature is triggered. During this feature, all symbols on the reel count as 2 symbols when calculating wins for the spin, which means you can get 10 of a kind winning combinations (and it's also easier to get a full screen of diamonds).

Free Spins

When 3 or more scatter symbols land on the reels, the Free Spins feature is activated, rewarding you 5, 15, or 30 free spins depending on how many scatters landed. During this feature, the higher-paying symbols and wilds appear stacked. When 2 or more scatter symbols land on the reels during a free spin, you’ll get 2, 5, 15, or 30 additional free spins, depending on how many scatters landed.

Bottom Line

Double Stacks looks simple, but it’s actually a bright and fun game that includes high winning potential, that frankly, has been missing from some of NetEnt’s previous slots. When you fill the grid with diamonds you can win the max payout of 1000x your spin, and this can theoretically happen more than once. Couple that with the Double Stacks feature that adds to your wins and the Free Spins feature that can award you up to 60 free spins, and you have a game that’s rather satisfying.
