Double Stacks is a 5 reel, 10 payline slot from NetEnt that can be played on all devices from just 10p per spin. With a fruit machine/neon theme, it’s all about stacked symbols which can give you 10 of a kind combinations. If you fill a reel with the same symbol, the Double Stacks feature is played meaning the symbols count as 2. There’s a Free Spins feature where up to 60 free spins can be won – the wild also appears stacked which makes it easier to fill the reels with double symbols. This can lead to wins of 1,000 times your stake on every spin/free spin.
Double Stacks is powered by Net Entertainment and is a 5 reel, 10 payline slot – it can be played from 10p to £200 a spin across compatible devices like smartphones and tablets. With a neon/fruity style theme, it comes with stacked symbols and a Double Stacks feature where a reel showing the same symbol is duplicated to give you double wins. There’s also a Free Spins feature where you can win up to 60 free spins with the wild appearing on the reels or in stacks.
Visually, Double Stacks reminds me of Twin Spin Deluxe – with a gentle soundtrack playing, you can see Double Stacks has fruit machine roots as well a neon style. Symbols on the reels include watermelons, plums, lemons, cherries, bells, 7s, bars and diamonds – there’s also a wild symbol which substitutes for all symbol bar the disco ball scatter.
Above the reels you will see the maximum payouts for the 4 highest value symbols – you can achieve these amounts by filling the screen entirely of that particular symbol. The 4 high paying symbols, the diamond, 7, bar and bell, can appear stacked on the reels to help you win more.
Now, when a reel stops and all symbols on that reel show the same stacked symbol, the Double Stacks feature is triggered. All symbols on the reel will then double – this means that the symbols on the reels will count as 2 symbols instead of 1. This means you can get 10 of a kind winning combinations. If you were to fill all the reels with double diamond symbols, you’d win 1,000 times your stake.
Double Stacks also comes with a Free Spins feature – this is played when you get 3 or more scatters anywhere on the reels. 3, 4 or 5 disco ball scatters will reward you with 5, 15 or 30 free spins respectively. During the feature, the wild symbol will also appear on the reels or in stacks – as well as 4 high value symbols.
This makes it easier to fill the reels with 1 particular symbol. Finally, you can retrigger the feature by getting 2, 3, 4 or 5 scatters – this will give you 2, 5, 15 or 30 additional free spins.
Double Stacks is quite a simple slot once you get spinning – it’s all about the stacked symbols which make it easier to fill the reel set with the same symbol. In the Free Spins feature, the wild can become stacked which will substitute for all symbols (bar the scatter) to increase your chances of winning big.
Medium variance, there’s up to 1,000 times your stake to be won on every spin/free spin – this is achieved by fill the reels with double diamond symbols or using the wild and diamond symbol in the Free Spins feature.
