Introduction of Double Stacks Slot  

NetEnt has received a lot of flak from its followers and the avid gamblers that many of its titles offer low potential. It looks like NetEnt has made some serious corrections in its ideology. The software provider has changed its formula and thinking process. NetEnt has mainly come out with an impressive Double Stacks slot to offer the bettors a chance to win 1000x of the stake on a single spin. The betting range allowed is from a minimum of €0.10 to a maximum of €200.00.   

More Important Information

The Double Stacks slot machine comes with 3 rows, 5 reels, and 10 betting lines. It falls in the classic-styled video slot category as it comes out with a fruit theme. The impressive feature of this fruity slot is the stacked symbols. Besides, it has other common features also. The impressive features that drive many gamblers to try it out in the licensed online casinos are free spins, stacked wilds on complimentary rounds, wild and scatter symbols. This medium to high variance title comes with an impressive Return to Player (RTP) percentage of 96.1%. The stacked premium icons that contribute to a win double up to offer impressive payouts. 

Since September 2018

The Double Stacks online slot machine was released in September 2018 and it soon became a huge hit among many of the classic fruit-themed slot fanatics. NetEnt has gone the extra mile to do away with low variance and low earning potential slots to bring out a power-packed and thrilling title. The icing on the cake is when you gain access to 30 free plays with stacked wilds on the reels. 

Game Symbols

As this is a classic fruit-themed slot, the wagers can find the regular fruit icons as the low valued symbols. They include melons, plums, lemons, and cherries. The high valued icons are bells, bars, lucky 7s, and diamonds. The golden star with wild written on it is the wild symbol. The 4 highest paying symbols can turn into stacked symbols and offer better and bigger wins. All you need to do is to line up three or more of the identical symbols consecutively on the active betting lines. If this happens, you get a payout as mentioned in the paytable based on the identical symbols. 

The diamond is the highest paying icon and landing five of these on an active payline results in 4.5x of the stake. If you happen to hit diamonds all over the 3×5 tiles, you enjoy a maximum win of 1000x of the stake. The wild and the scatter icons of the Double stacks slot do not appear stacked in the base game.

Double Stacks Slot-Important Features and in-Game Bonuses

Like in many other slots, the Double Stacked free online slot comes with the wild and the scatter icons. These symbols have a role to play in helping the gamblers gain some wins. The wild and the scatter do not offer any payout as such as the other fruit icons and the premium symbols and they just contribute to boosting your wins. 


The wild star is the wild symbol here. When a wild lands on the reels after a spin, it will substitute the other low valued icons other than the scatter symbol. By matching with any other symbols, it helps you to create a winning combination. Any line of icons you create by using the wilds as a substitute turns into a truly winning combination. Therefore, hitting wilds during a spin boosts your chance of winning.  

Free Spins

To activate the free spins round, you need to land three or more of the Scatters anywhere on the reels. The scatter icon is the Disco Ball. Landing three scatters rewards you 5 complimentary rounds and the free rounds go up to 15 for hitting 4 scatters on the 3×5 grid. If you can land 5 scatter icons anywhere on the 3×5 grid, you can avail 30 complimentary rounds. There is every chance for you to re-trigger this feature if you land three or more of the scatters during the bonus round. So, if you are lucky, you can get unlimited free spins when playing the Double Stacks slot game. 

During the additional bonus rounds, 2 scatters offer 2 extra spins and 3, 4, or 5 scatters reward you with 5, 15, or 30 free rounds. Therefore, if you are lucky, you can see big and massive wins coming your way. They can stack up like anything during these free spins. During these extra spins, only the highest paying icons like the bars, lucky 7s, bells, and diamonds will show up on the reels. They can also appear stacked on the reels. Apart from this, you can see the wild icon to show in the stack or the reels of the complimentary spins. The wilds that land on the reels during the free spins round will double up to increase your winning potential. 

Double Stacks Slot Feature

This is the most important feature of this online slot machine. You can activate this feature when all the symbols that land on the grid are identical after the reels come to a stop. It is evident from the name of the feature that the icons will tally as two instead of one. You end up with 10 identical symbols on the reel. You get a payout as mentioned in the Double Stacks slot paytable above. If you can spin and land diamond icons on all the tiles of the reels set, the symbols double up offering you a massive win of 1000x of the wager. Most importantly, your aim as an avid bettor should be to land five stacked diamonds on the payline to receive a payout for 10 diamonds.
