Double Stacks Introduction

Double Stacks slot is a classic-style slot machine. NetEnt have gone back to basics with this one, creating a glossy, bright, radiant Vegas classic. It’s a particularely tried and tested theme, but for those gamers who are after quick and easy spins, video slots like Double Stacks will be perfect.

The slot reel is your standard five by three, and the symbols are your slot machine staples. There are eight normal symbols that vary in payout value (diamonds, sevens, a bar, the bell, cherries, lemons, grapes and melons) and two feature symbols: Wilds and Scatters (more on these below). The layout of the betting bar is clean and simple, and just like a classic slot machine, everything is easily accessible and in eyesight.

Here’s NetEnt’s own Double Stacks guide to shine some more light on proceedings.

Mix Nostalgia with Modern Tech and Play the Mobile Double Stacks Slot Version

A glossy resolution on both desktop and mobile is pretty standard for an iGaming slot these days, and this game is in the same realm thanks to the advanced HTML5 tech that NetEnt have programmed it in.

So, you can spin away on the Double Stacks mobile slot safe in the knowledge that the desktop experience is being replicated – in crips HD too!

Double Stacks Game Tutorial

As we mentioned above, NetEnt have deployed the favoured 5×3 slot structure here. The game comes packaged with 10 fixed bet lines, so again quite a simple premise – emulating that classic casino game feel. Players can find a list of the bet lines by pressing the ‘?’ button, if they wish.

However, despite the easy nature, the game also has two feature symbols – Wilds and Scatters – which enable some exciting features!

Wild Substitutions

The Wild symbol is unmissable: a bright gold and purple star with the word ‘Wild’ embedded across its front.

The premise of Wilds is simple: they substitutes for all other icons on the grid, except for Scatter symbols. This means that Wild symbols can feature in and complete your betting lines to give you a helping hand.

Double Stacks Feature

While playing, the Double Stack feature may grant players double the value of a symbol. Essentially, if an entire reel is entirely covered by one of the same top four paying symbols, the icons in question will suddenly sprout a twin – with these places now counting for two instead of one.

You can see a visual example of the this feature in the video above, or you can simply follow the ‘?’ in our free-to-play Double Stacks slot demo for more details.

Maximum Payouts

Now, what of those eye-catching amounts above the reels!?

Lift your gaze to see four large payouts listed for the diamond, seven, bar, and liberty bell symbols. If you manage to achieve a screen full of one of these symbols, the corresponding payout will be dished out to really boost your coffers!

Double Stacks Free Spins Feature

Also, a Free Spins Bonus Round on Double Stacks is not a fantasy but instead a reality!

If players get three or more Scatter symbols within the main game (landing anywhere), then the Double Stacks Free Spins Bonus Round will be activated. When this round starts, it’s also possible to see Wild symbols included as part of this Stacks feature, just to give the potential winnings an extra leg-up.

You don’t just get one free spin though! Like a classic slot machine, this depends on how many Scatter symbols initially fall:

  • 3 Scatter symbols = 5 free spins
  • 4 Scatter symbols = 15 free spins
  • 5 Scatter symbols = 30 free spins!

Retrigger Free Spins

Think it’s all over? Not just yet!

That’s because if two or more Scatter symbols then appear in the same spin during the Free Spins round (again, anywhere on the reels), this will retrigger even more free spins! Like before, it all depends on how many extra Scatters fall:

  • 2 Scatter symbols = 2 more free spins
  • 3 Scatter symbols = 5 more free spins
  • 4 Scatter symbols = 15 more free spins
  • 5 Scatter symbols = 30 more free spins

Double Stack Bet Limits

In Double Stacks, bet levels range between 1 and 10, whereas coin values vary from 0.01 to 2. In terms of monetary wagers, these totals allow you to place a minimum bet of €0.10 per spin, or a maximum bet of €200 per spin.

Double Stacks Maximum Win

And what of the maximum win available on Double Stacks? On a single bet line, it can reach up to 10,000 coins – which translates to up to €20,000!
