Double Stacks is a NetEnt slot game released in 2018, and the main feature of the game is the ability to double the symbols on one reel, which can lead to ten-of-a-kind wins! But that's not all as there's also a free spins game with up to 30 free spins and doubled Wilds!
Double Stacks Slots Data
Double Stacks slot gets its name from the feature that doubles the stack. When one of four high-value symbols appears stacked on an entire reel, the symbols will automatically be doubled and will count as two symbols each. During the free spins game, low-value symbols and Wild symbols can also take advantage of the feature.
This feature allows up to 10 symbols of the same kind to be on one five-reel payline, and in case of top two symbols, Diamond and 7, the prizes are significant, and for other symbols they are not as spectacular and it's in fact a necessity to get more than 5 of the same symbol to get a decent win. Without the Double Stacks Feature it's just not possible to make any money.
The free spins feature is triggered with Scatters, and you need to land at least three. You'll get 5, 15 or 30 free spins for three, four or five Scatters respectively. Free spins can be re-triggered with the same values, plus +2 free spins if you land two Scatters. During the free spins, low-value symbols and, crucially, the Wild symbol, will also be affected by the Double Stacks Feature. Doubled Wilds are capable of producing a big win or a mega win.
The game is played on a standard 5x3 board, with 10 fixed paylines, which is a familiar NetEnt setup used very often. Theoretical return to player (RTP) is 96.10%, which is a decent number, and variance is medium. This is an easy to play slot game that will issue wins often enough, yet the biggest prizes are not that big. On top of the reels the maximum payout values for landing a full board of the same symbol are displayed, and the values are far from life-changing. This is yet another fun and easy to play medium variance slot by NetEnt.
Double Stacks Slot Theme
Double Stacks uses a well-known theme with Bars, 7s, Diamonds and Fruit symbols, so there are no surprises there, but NetEnt did it well and managed to breathe in new life into this familiar theme. The common theme puts the focus on the bonus feature of the game, and it works well.
