Double Stacks bonus features
NetEnt is transporting us back to the glory days of slot machines, back when they were also called fruit machines. Watermelons, cherries, lemons, and plums make up the basic slot symbols (and more of your five-a-day). The four high-paying symbols are the bar, the bell, the diamond and the lucky number 7. Fill the screen with these symbols to boost your winnings.
The diamond symbol has the highest value. Landing five of these on a payline will reward the player with x4.5 their initial bet. The Scatter symbol is a disco ball – a fitting choice for this groovy slot!
Wilds
The Wilds symbol is a pair of golden stars. It can substitute for any other symbol on the screen except the Scatter.
Double Stacks feature
This feature is the big draw on this game. When identical symbols appear on top of one another once the reels stop after a spin, the Double Stack feature is activated. When that happens, all the stacked symbols are effectively doubled, with each single symbol counting as two symbols.
So if five winning symbols land on a payline, the Double Stacks feature will turn them into ten winning symbols, thus doubling the size of the winning combination. A winning combination of diamonds, for instance, will translate to a win of x1,000 the original wager.
Double Stacks free spins
Double Stacks also feature a Free Spins bonus feature. This is triggered when 3 or more Scatter symbols appear anywhere on the game screen. 3 disco balls will land you 5 free spins; 4 Scatters mean 15 extra spins; 5 Scatters reward with 30 free spins.
Wilds and the 4 premium, high value symbols can appear during free spins, with stacking also possible. This means that it is possible completely fill the screen with a single symbol and landing a big win.
Free spins can be re-triggered by Scatter symbols while the feature is active. Two, 3, 4, or 5 Scatters will rewards with 2, 5, 15, and 30 extra free spins, respectively.
Double Stacks jackpot
Double Stacks does not offer a progressive jackpot. There is plenty of opportunity for big in-game wins though, thanks to those Double Stacks and Free Spins features.
