Double Stacks Features – Reels, Paylines & Theme

The Double Stacks online slot follows a format of five reels, three rows, and 10 fixed paylines. This scatter is one of the most important symbols, and it takes three of the same symbol to activate the perks.

If you obtain three scatters, you receive five free spins; get four, and you get 15 free spins; get five scatters, and you earn 30 free spins. Here’s a quick graphic breakdown for your perusal.

▶️ Type of Slot Video Slot
▶️ Payout Rate 96.10%

Another wonderful trait of the Double Stacks slot is that it really caters to players of all budgets, as the limits between bets ranges from $0.10 – $200. However, we encourage you to always gamble responsibly. Such flexibility allows players to enter with low stakes and have a fighting chance of increasing their winnings.

Thankfully, multiplier bets are available, although they are not active during the free spins feature. However, more spins inside the free spins rounds are conceivable and can be continually regenerated. In our book, such appealing features place Double Stacks among players’ favorites.

Double Stacks Slot RTP, Symbols & Payouts

This might sound enticing, but how fair is this game in reality? As it turns out, the Double Stacks slot RTP is 96.10%, indicating a game of medium-to-low volatility. Apart from the ”scatter symbol”, the most important symbol for gameplay in Double Stacks is the diamond.

Watermelons, plums, cherries, and lemons are the lower-hanging fruits so to speak, while 7s, bars, bells, and diamonds are the higher-paying symbols in Double Stacks. Below is a useful graphic for a quick visualization:

Double Stacks Symbols with Payouts
RTP Rate: Highest Paying Symbol: All Symbols: Paylines: Max. Win
96.10% Diamond 8 10 1,000 x stake per spin

The double stacked pay symbols are the major draw of this online slot (hence the name). Five of the same kind might pay up to 4.5 times your wager. However, the Double Stack slot feature may transform this into a ten-of-a-kind immediately. If Luck is on your side, you can easily maximize any payouts.

If you land a full screen of double diamonds (or diamonds and wild symbols), then you stand to win exactly 1,000x your stake. During free spins rounds, this can even explode up to 10,000x. If you want to know more about the optimal winning combinations, you should read the fine print first.

Of course, sign up with a reputable casino site with generous bonus offers for US players to get the most out of your gaming experience.

All Bonus Features – Potentially Endless Free Spins and Double Stacks

As we said, the free spins bonus is easily activated. All you need to do to trigger these free spins is get three of any symbol. The game also features wild substitutions, and ‘wild’ double stacks symbols that can bolster your payload frequently appear. The bonus sign is a glistening, vibrant circle with the word “scatter” written in it.

Wins for a single five-of-a-kind vary from 2x to 4.5x the wager, and when double stacked premium symbols occur, the payouts increase to between 10x and 100x your stake. We must also acknowledge that it’s fantastic that free spins can be continually rewarded throughout free spins rounds.

When the Double Stack option is enabled, the ride becomes considerably smoother. To clarify, when a full stack lands on a reel, the symbol on that reel will double in value. This nifty feature only adds to the excitement and potentially lucrative betting opportunities for astute players.

During our investigation for this Double Stacks slot review, we were pleased by how user-friendly the design was for this particular slot. Since the RTP is pretty standard, the reels frequently land in the desired order, even during the free spin rounds.

Still, at the end of the day, we recommend you play a free version of this game first to see if the bonus feature occurrence rate suits you.

The Author’s Opinion on Double Stacks

In my opinion, the Double Stacks slot is a fun throwback to simpler times, and its classic fruit machine design will appeal to veteran gamblers and newcomers alike. In any event, the game has a simple and engaging premise, and the Double Stacks slot RTP is respectable.

I can see why some seasoned slot fanatics might give it the slip. Adding more gameplay dynamism in the form of bonuses would elevate the experience considerably. However, the fair RTP and plentiful free spins make this a game well worth your time.
