Play Double Stacks Slot For Double Fun

Double Stacks is 5-reel 3-row and 10-line video slot will take you back to slot basics, as its functions and features are reminiscent of the early days of slot gaming.

This online slot is played with ten fixed lines where you can choose from 1 to 10 bet levels and various coin values using the control options at the bottom of the panel. For those players who are new to the scene and want to bet low, you can start at a coin value of 0.01.

For those willing to crank it up a notch, the maximum that you will be able to bet is a total of 2 coins per line per spin. This means that the default minimum bet is 0.10 per spin, while the maximum is a staggering 200 per spin.

How to play Double Stacks

After you’ve chosen your preferred bet amount, just hit that funky ‘Spin’ button at the centre of the control panel and watch those classic fruit and standard slot symbols turn.

How to play Double Stacks

In order to access the Free Rounds Values, you can set the level at bet level 1, using all 10 bet lines, and with a 0.01 coin value (which will cost you 0.10 per spin).

The RTP of this game is 96.10%, which means you’re going to have to put some effort into it in order to get your money’s worth.

Our Favourite Double Stacks Attractions

Double Stacks brings back the endless fun of the 5x3 classic slot game theme that never fails to impress. The mother of all slot-types, its basic design, vibrant colours, and happy-go-lucky vibe makes it a game that most players find comfortable to play each time that they come across it.

Not only is it bursting with a variety of colours and tasty fruit, but its Double Stacks and Free Spins features have us hungry for more.

Double Stacks Special Features

The special features of this game are packed to the brim with stacked Wilds and awesome payouts. For your chance to win a maximum of 10,000 coins, read on to see how to access the Free Spins and the Double Stacks features.

Double Stacks Feature

This is the online slot’s own special feature, and unique in its bonuses as well. It is triggered when a reel stops and all symbols on it are of the same type. Then, when triggered, the feature allows that all of the symbols on the reel will count as two symbols when calculating wins for the current spin.

It is important to note that during the base game, only the four highest-paying symbols will appear in stacks on the reels.

Free Spins Bonus

The Free Spins Bonus feature is the main attraction of this game - and it’s as lively as the game itself.

Three or more Scatters appearing anywhere on the reels in the base game activates Free Spins:

  • 3 Scatters = 5 Free Spins
  • 4 Scatters = 15 Free Spins
  • 5 Scatters = 30 Free Spins

Additionally, the Wild symbol and the four highest-paying symbols appear as stacked. During free spin rounds, two or more Scatter symbols anywhere on the reels will award additional Free Spins:

  • 2 Scatter symbols = 2 Free Spins
  • 3 Scatter symbols = 5 Free Spins
  • 4 Scatter symbols = 15 Free Spins
  • 5 Scatter symbols = 30 Free Spins

So Double Stacks isn’t your typical classical slot casino game after all. With the addition of its own feature which doubles your wins through stacked symbols, along with a Free Spins feature that just keeps on giving, there’s always more to gain when playing this retro online slot game.
