Play Double Stacks Slot For Free

Double Stacks is a Net Entertainment slot machine, and one which is perfectly capable of delivering slot action whether you favour playing on your mobile phones and tablets or laptop computers.

The game features plenty of classic slot imagery, such as bars, bells, cherries, and diamonds, but it also offers a series of non-progressive jackpots. Icons appear stacked on the reels of this game, double-stacked, even, and this all contributes to the likelihood that you’ll land a win when playing the slot.


Net Entertainment’s Double Stacks slot bears a striking resemblance to several of their other top slots, such as Twin Spin. The game may look primitive, but it offers a lot more in terms of special features than its fruit and classic slot theme suggests. A decent RTP (return to player) rate of 96.10% is present in the slot, and that is common practice for this software provider.


How to play

Like most other games from this software provider, betting levels and coin values are adjustable, even if the number of lines you play with are not. For the record, there are 10 paylines spread over the 5 reels of the slot. Players can use the coin value and betting level buttons to alter their stakes so that the fall anywhere between the $0.10 minimum and $200 maximum limits.


Wild symbols: Wild symbols appear as stars in this game. The icons are impossible to miss, as they have “wild” written across them. Naturally, wilds can substitute for all other symbols barring scatter icons.

Scatter symbols: These pop up as retro looking, circular emblems. Again, a word is written across these special symbols, with “scatter” this time spread across them. Players can expect to be able to trigger a free spin bonus when 3 or more appear anywhere on the reels.

Double stacked symbols: When players land a reel filled with the same stacked symbols, those symbols will count twice. This means that you can land double the cash prizes. In theory, you can, therefore, win with ten-of-a-kind winning combos. Fill all the reels with the same symbols, and you will win whatever the cash prize happens to be displayed above the reels.

Free spin bonus: Players who land 3, 4 or 5 of the groovy scatter icons in any position on the screen will start the bonus round with 5, 15 or 25 free games. In the feature, wild symbols can also appear stacked on the reels, which can help you land wins that little bit easier. Players can also win an additional 2, 5, 15 or 30 free games if they land 2, 3, 4 or 5 scatters on the reels in this bonus round.

Maximum pay-outs

As mentioned, this slot contains an RTP rate of 96.10%, and there are four major cash prizes which can be won when you fill the reels with those symbols. Players need only look above the reels to see what those prizes are and how they can win them. The top prize is worth 1,000 credits and is yours if you can land 5 reels filled with diamond icons.


Double Stacks may look like Twin Spin, but its features are wholly different. This is a game which continues NetEnt’s proud history of developing quality, original gaming engines for their slots. If you like your classic slots but fancy playing one with special features which are a touch more modern, you can’t go far wrong with this release.
