NetEnt's slot game called Double Stacks is an exciting option for players.

Once you have made your choice between playing Double Stacks for fun or for actual cash, a popular feature offered by many virtual gambling platforms, you are now ready to adjust the wagering sum.

The range of possibilities in this game is vast, with players able to adjust both the level and coin value to set their bet anywhere between 0.10 and 200 coins.

I've always found it fascinating how different buttons on a slot machine can affect your gameplay. Take the "Spin" button, for example. With just one press, it sets the reels in motion, but it's important to remember that it only uses the current bet amount. On the other hand, there's the "Auto Play" button, which introduces a whole new level of convenience. Once activated, it allows the machine to spin the reels automatically, so you can sit back and enjoy the game without continuously pressing the button. Lastly, we have the "Max Bet" button, which is for the risk-takers out there. This button ensures that you place the highest possible bet, typically 200 coins, giving you a chance to win bigger prizes. It's quite exciting to have these options at your disposal, each offering a different way to play and potentially win on the slot machine.

Game rules

• Double Stacks features a set of 10 permanent paylines, along with 5 spinning reels and 3 rows.
• The left-to-right sequence is always where the combinations occur.
• When larger symbols occupy a whole reel, they will be seen as duplicates.
• The free spins are activated when three Scatter symbols appear.
• A single spin can yield a maximum win of 1,000 times the initial bet amount.

I had the most incredible experience playing this online slot machine called Double Stacks. Let me tell you, it's like nothing I've ever seen before. This game has a total of eight symbols, but what's truly fascinating is that four of them are considered high symbols. And here's the kicker - these high symbols have this amazing ability to double in number if they happen to show up alone on an entire reel. Can you believe it? It's like having double the chances of winning big! It really adds a whole new level of excitement to the game.

I must say, it's quite fascinating when such an occurrence takes place. You see, it can lead to rather notable variations in one's earnings. Take, for example, the pinnacle symbol, the Diamond, which graciously rewards the player with a staggering 1,000 times their initial bet - an absolute triumph, to say the least. Now, let's compare that to the second tiniest symbol, the "7", which, in the presence of this very same bonus, would grant a respectable payout of 500 times the original wager. This stark contrast in rewards is truly something to behold.

In this game, you'll find a star symbol acting as the Wild, capable of replacing all the other symbols. On the other hand, the fruits and classic slot machine symbols represent the four smaller symbols, offering comparatively lower payouts.

With only 10 paylines, the potential winnings can be astonishing if you manage to land the perfect combination of the top four symbols.

The Double Stacks game provides an enjoyable bonus feature by doubling the high-paying symbols when they fill up a whole reel. However, there are other exciting bonuses to explore as well.

In my personal experience, I can confidently say that the key to unlocking a whopping 30 free spins at once lies in the Scatter symbol. This symbol is truly remarkable as it bears the very word it represents. To achieve this feat, one must strive to obtain a minimum of three of these symbols in a single round, regardless of their position on the reels. It's an exhilarating feeling when you see those symbols align, knowing that a multitude of free spins awaits you. With 5 to an incredible 30 spins ready to be unleashed, the possibilities for victory are endless.

• 3 Scatter: 5 free spins
• 4 Scatter: 15 free spins
• 5 Scatter: 30 free spins

In the bonus rounds, Wilds may also emerge to fill up an entire reel, much like the premium symbols found in the regular gameplay.

During the free spins round, it's worth mentioning that the acquisition of extra Scatters has the delightful effect of augmenting the quantity of complimentary spins by the identical figure indicated earlier. It's interesting to note, however, that a peculiar exception arises in this particular scenario: while immersed in the realm of free spins, even a mere duo of Scatters has the power to bestow upon the fortunate player an additional boon in the form of two extra spins, an unexpected and welcome surprise indeed.

Released in 2018, Double Stacks is a game that boasts contemporary visuals. With its vibrant sound effects and an array of vibrant hues, the game creates a lively and enjoyable gaming atmosphere for slot players. The graphics are up-to-date and aim to provide a fun-filled gaming experience with their extensive color palette.
