Pros & Cons - What Works and What Does Not

Netent had a lot to prove going into 2018, having lost some of the company's glory to upcoming developers who came into Canada with pomp and colour on thrilling releases. Therefore, the designers did not hold out on incorporating in-game bonuses and special symbols to help players boost their winnings. In addition, the slot was created with the modern-day punter in mind and included unique features that add to the overall experience. Despite all efforts to make the Double Stacks slot the best for players in 2024, it does not satisfy every gambler's dreams. Following thorough testing, our Online Casinos CA review team came up with a list of items that work perfectly and what we think could be missing.

What Works

  • Optimized for mobile
  • 3 bonus features
  • 1000x possible win in one spin
  • 10 unique paylines
  • 5 by 3 gridline
  • C$0.10 to C$100 bet range

What Doesn't Work

  • Vintage-style graphics
  • On-loop sound effects

Double Stacks : Theme and Overview

Double Stacks was released in 2018, adding to the rich collection of creative slots from Netent. Players spin reels arranged in horizontal and vertical lines, with 5 reels running horizontally and 3 lines running vertically. From the reels, you can expect to win on 10 paylines by landing a minimum of 3 or more matching symbols. Classic symbols enhance the Retro theme on this video slot, including high-value ones like the Bar, Bells, 777s, and diamonds, plus low-value icons such as cherries, melons, lemons, and plums. Lucky players get to walk away with massive prizes based on how much they put down in wagers, with the highest possible win being a 1,000x bet multiplier. Bets on the high volatility slot range between C$0.10 to C$ 100, enabling participants to win up to C$10,000 in a single session of spinning the reels.

How to Play Double Stacks

Netent created the Double Stacks slot with two ways in which players can enjoy spinning the reels. i.e. free play mode and real money mode. In the Double Stacks free slot game, you get a chance to test all the features, including placing bets and activating bonuses, but you cannot place real money wagers. In the real money mode, you can wager real money by following the steps outlined below and win an amount equal to the bet multiplier activated depending on the symbols on the reels.

  1. Open Game: Log in to a Canadian online casino with Netent games and search for the title in the lobby, then click on the game's thumbnail icon.
  2. Select Game Mode: Choose between real money mode and the for fun demo mode. In demo mode you only get to test the game, while real money mode gives you chances to wager and win real money.
  3. Set Bet Amount: Specify the amount you want to bet on each spin. The betting range varies between a minimum of C$0.10 and a maximum of C$100.
  4. Set Bet Mode: Here, you can opt to set manual bets, which will require you to activate each bet, or set automatic bets, in which you can let the game automatically execute up to 1,000 bets.
  5. Spin the Reels: In the final step, hit start to spin the reels. Basic wins on the game start with three matching symbols lining up consecutively on reels 3 to 5 when the reels stop spinning.

Double Stacks Slot Bonus Features

Netent slots come with a wide array of bonuses you can activate with no deposit. Simply match the correct symbols sequence to active free spins and respins once you sign up at the best Netent casinos like Casumo and PlayOJO. From the title, you can easily tell that the outstanding feature of the game works by doubling your win, but the reels contain a hidden gem in the form of free spins.

  • Double Stacked Symbols : Any of the four premium symbols can appear stacked when playing the base game, while the free spins mode comes with extra opportunities for the wild symbol to appear stacked. Stacked symbols on one reel count as two, meaning that only one more occurrence of the same symbol is required to win a three-of-a-kind multiplier. On the same note, landing 5 staked symbols activates a ten-of-a-kind bet multiplier.
  • Free Spins : Scatters appearing on the reels is good news, with 3, 4, and 5 scatters activating 5,15, and 30 free spins, respectively. And when spinning the reels in the bonus round, you can activate extra respins if 2 to 5 scatters land on the reels. The stacked feature is deactivated when playing in the promo spins round, but landing a series of 5 wilds promptly triggers every symbol to appear stacked and payouts made in the value of the diamond symbol.

RTP, Volatility, and Jackpot

The Double Stacks slots RTP averages at 96.1%, which is no surprise for a game developed by Netent, one of the best-known software developers in Canada. From the statistic gathered, the average hit frequency is about 16% and matching stacked symbols comes with amazing payouts, making it a high-volatility slot with instant payouts. Unfortunately, you cannot win a progressive jackpot prize on this slot.

Payouts on the reels from a series of matching low-value symbols range between 2x to 4.5x, but combinations that include high-value symbols can take up the multiplier to 10x. Things get better with the stacked icons, which count as double, taking the bet multiplier to between 10x and 100x on ten-one-of-a-kind combinations. The ultimate win comes from a spin that ends up with a combination of 5 stacked diamonds or stacked diamonds and wilds, in which you get 1000x of your wager.

Double Stacks Popularity at Real Money Online Casinos

When looking for the best slot game, players majorly consider the return to player percentage and variance, both of which are optimally balanced in this game. The 96.1% RTP is just a little above the average RTP on popular slots, and the high volatility rate works well to raise the thrill of spinning the reels. Doubling the value of high-value symbols which appear stacked activates rare rewards that you cannot easily find on any other game within Canada, and the 1000x ultimate bet multiplier puts participants in the lead. All things considered, it is no surprise that the game ranks top in many Netent casinos operating in Canada.

Enjoy winning on double-valued symbols when you spin the reels and land a series of stacked symbols on Android and iOS mobile casino apps. If you prefer no download instant play, you can still have the time of your life spinning the reels in flash mode using the mobile or PC browser interface.
