What Are Stacked Wild Slots?

Just like any other type of wild, stacked wilds act as a kind of “joker” that can substitute any other icons on the reel to complete a winning line.

What’s special about stacked wilds specifically, though, is that they usually come in pairs of 2, 3, 4, or 5 symbols that can even cover an entire reel when they drop! For the players this means way bigger winnings compared to regular wilds because you can potentially get multiple payouts with just a single spin.

This is why stacked wild slots are such a popular choice when it comes to slots. Who can resist the possibility of such an advantage?

How Do Stacked Wilds Work?

Now that we know what they do, you might be wondering how exactly stacked wilds work?

Well, it’s actually pretty simple. Stacked wilds function in a similar way to expanding wilds in that they can expand to cover the whole reel. However, unlike expanding wilds, stacked wilds are single symbols that get dropped.

How much of the reel or which portions can get covered by stacked slots can vary from game to game and depends on individual rules. It could be the whole reel or just the bottom section.

Keep in mind that you can always check these rules in the paytable of any given game. Just look for a button that indicates “paytable”, “menu”, “info”, or something else along the same lines.

7 Other Popular Types of Slots

If you like the sound of stacked wilds, check these other types of slots. Each one comes with its own unique set of advantages and features we’re sure you’ll love!

#.1 Low Stakes Slots

Otherwise known as penny slots, low bet, or low balance slots, low stakes slots are a type of slot game that has a very flexible lower betting range, sometimes starting as low as £0.01.

This is perfect for both beginner and experienced players who want to enjoy long sessions of slot gameplay while still getting consistent payouts and having a chance of hitting the jackpot.

#2. High Stakes Slots

If you can place super low bets with low-stakes slots, high-stakes slots allow you to make BIG wagers. You can usually bet as much as £300 per spin with these super fast-paced games.

High-stakes slots are usually played by high rollers who love the thrill of taking big risks with large amounts of cash!

#3. Sticky Wild Slots

Wild cards are always a welcome sight for slot players. Unfortunately, they usually make super brief appearances. That’s not the case with sticky wild slots, though.

These games feature wilds that stick around for several spins, giving you way more chances to score payouts than the average slot game.

#4. Tumbling Reel Slots

Tumbling reel slots are still a relatively new but popular type of slot. Also known as rolling reels, cascading reels, falling symbols, or avalanche slots, these slots have a super cool feature that allows you to get multiple payouts with just a single spin.

Once you get a winning combination on a tumbling reel slot game, the winning symbols either disappear, explode, or crumble away, leaving space for new symbols which drop down to take their place. This process continues as long as you keep getting winning combinations with the new symbols.

#5. High Payout Slots

If you’re looking to win big on slots, high payout slots are probably your best bet. These have the highest Return To Player (RTP) percentage, giving you the best probabilities to get payouts.

With so much competition between casinos, high RTP percentages are often used to attract more players, so you can always find these advantageous machines at most casinos. The best casinos offer slots with RTPs as high as 99.7%!

#6. Win Both Ways Slots

With win both ways slots you can make winning combinations by moving either way on the reels, which doubles your chances of getting a payout!

This one is perfect for players who get easily frustrated when the symbols don’t quite match up.

#7. Progressive Jackpot Slots

One of the most popular types of slots, progressive jackpot slots attract players with their massive jackpots.

For this type of slot, there is no single jackpot per machine. Instead, there is one huge jackpot with around 10% of every wager being collected from all of the machines taking part in the progressive jackpot. This means that you could potentially win way more than what a regular slot machine could offer.
