What Are Stacked Wild Slots

Like any other type of “wild” in a game, stacked wilds play the role of a "joker" of sorts, substituting other symbols on a slot reel to match a payline completely. Depending on the rules, how much of the slot reel can get substituted by stacked slot symbols generally varies from game to game. It may, at times, be the entire reel or only the bottom portion.

For a bit of history, when the first-ever traditional slot machines became popular several years ago, they did not have any stacked wild features. The feature came out later in brick-and-mortar casinos found in Las Vegas and other gambling locations.

Today, you will find many stacked wild slots games at casinos, online and land-based. They became highly popular due to the added excitement and benefits they offered. In some cases, substantial wins with stacked wilds can also offer life-changing money. Some slot games offer the possibility of stacked wilds on every reel, whereas others merely have them appear on certain reels. Many slot games having bigger chances of stacked wilds on every reel have higher variance. Stacked wild slots online casinos often offer stacked wilds with additional enhancements to add a bit more excitement to the process.

If you are wondering how these differ from Expanding Wilds, they are essentially quite similar. However, the main difference is that stacked wilds are static and not dynamic. Beforehand, they land on the slot reels in their “stacked wild” state. On the other hand, an expanding wild may land on a reel in one form and change its position and size right after it settles (hence explaining its dynamic nature).

How to Play Stacked Wild Slots

Playing stacked wild slots online is simple. You can treat stacked wilds as you would normal wild symbols while playing a game of slots. As we established earlier, stacked wild symbols are just a couple or more wild symbols are seen next to each other on the slot's reels. These often cross multiple paylines while you play, sometimes offering more wins at once.

These are not only found on slot reels during bonus rounds, but they are often part of the base gameplay (in the case of many game titles). Below are some tips you can keep in mind while you play at slots online casinos:

  • Learn from the experts: If you are somewhat new to playing stacked wild slots online, closely note how experienced players do it.
  • Start Small: Beginning with a small stake is very helpful, especially when testing the waters. While there is an option to play for free, this technique will help you understand the rules.
  • Play by the Rules: This has to be the most important part of playing at stacked wild slots machines and online.

Odds to Win Stacked Wild Slots

All slots are created differently; however, if you play stacked wild slots online, funding high RTP games should not be too hard. Consider consulting the game developer’s websites, and they will tell you the RTP percentage of each slot game. When it comes to live casinos, finding high payout stacked wild slots machines is trickier. However, you can ask local players. 

In any case, try to figure out which games have the highest RTP percentage, and you will be able to increase your winning chances at your chosen stacked wild slots game dramatically. Besides that, go with games offering a decent variety of wild symbols. The more wild symbols there are, the better your odds are of forming winning combinations.

You can also look for stacked wild slots games with higher bet limits. The more you can bet on every slot spin; the more money is at stake. This, in turn, increases your chances of winning more money.

Price of Each Spin

When it comes to free online stacked wild slots, you do not have to bet money. This option is great for practising strategies, trying games and whatnot.

As for paid games, you can bet from $0.20 to $100 per spin with average slot games. However, some games also feature minimum bets as low as $0.10, $0.08, $0.05, or even $0.01 per spin. In terms of how high the price can go, some games accept maximum bets going as high as $1000.
