What Are Stacked Wilds?

Twilight princess Stacked

Stacked wilds refer to two or more wild symbols that appear vertically stacked on a single reel. This creates a column of contiguous wilds that essentially functions as one giant wild symbol.

Standard wild symbols in slots can only substitute for one symbol at a time on the reels. Stacked wilds build on this by allowing a group of wilds to stand in for an entire section of symbols vertically.

Some key attributes of stacked wilds:

  • They always appear vertically, covering multiple symbol positions on a single reel.
  • The number of wilds stacked can vary, often 2-5 wilds clustered together.
  • In some slots, stacked wilds may cover an entire reel.
  • Stacked wilds boost the chance of hitting winning combinations across paylines.
  • Their clustered formation leads to higher volatility and bigger potential payouts.
  • Stacked wilds are valued for their ability to trigger multiple wins from just a single spin.

How Do Stacked Wilds Work?

Whenever a column of stacked wild symbols lands on the reels, they will substitute for any regular symbol in their path. This allows them to potentially complete multiple winning combinations across various paylines simultaneously.

Stacked wilds mechanics

For example, if a stack of 3 wild symbols lands on reel 3, every payline running through that reel now has a greatly improved chance of forming a win. The stacked wilds can stand in for any 3 adjacent symbols needed to make a matching combo.

As a result, it’s common for slots with stacked wilds to award several wins on a single spin. The more paylines available, the higher the likelihood that stacked wilds will trigger multiple wins together.

This is why stacked wild slots tend to be on the volatile side with a high hit frequency – their ability to trigger several wins at once increases the potential payouts per spin.

Stacked Wilds vs. Expanding Wilds

Expanding wilds are another popular type of special wild in modern video slots. While they sound similar to stacked wilds, there are a few key differences:

  • Stacked wilds always cover multiple symbol positions on a single reel vertically.
  • Expanding wilds start as a single wild symbol that can expand to cover an entire reel horizontally.
  • Stacked wilds boost winning chances across multiple paylines at once.
  • Expanding wilds impact a single payline but with higher payouts.
  • Stacked wilds trigger more frequent but smaller wins.
  • Expanding wilds lead to less frequent but larger wins.

So in summary:

  • Stacked wilds = multiple smaller wins per spin.
  • Expanding wilds = fewer but bigger wins.

Both special wild features make slots more exciting to play. But stacked wilds provide a higher hit frequency for keeping gameplay lively.
