What are Wild Symbols?

Before diving into the expanding wilds, let’s cover what wild symbols are in general. In slot games, they serve as a substitute for other symbols to create winning combinations. By replacing other symbols on the reels, wilds increase your chances of landing winning combinations and potentially securing big payouts.

How Expanding Wild Slots Work?

Hitting an expanding wild for the first time may seem unusual to you as it behaves like no other symbol, despite that initially, it looks like a regular wild.

Expanding wilds take the concept of wild symbols to the next level. When such a symbol lands on a reel, it expands vertically upwards and downwards to cover the entire reel, transforming all symbols on that reel into wilds.

This expansion can lead to multiple winning combinations across various paylines, boosting your chances of scoring a significant win.

Not all slot games feature expanding wilds, and the specific mechanics may vary between games. For example, some slots may have expanding wilds on particular reels only, while others on all reels.

Some expanding wilds may trigger bonus features or come with additional multipliers, so it’s essential to understand the rules and paytable of each game.

Advantages of Expanding Wild Symbols

We have gone through how the expanding wilds work, so let us take a look at the benefits you get from them.

Increased Winning Potential

As expanding wilds cover entire reels, they create multiple winning combinations and increase your chances of securing a large payout.

In games where wilds serve as a jackpot symbol, winnings are boosted even further.

Enhanced Excitement and Anticipation

The appearance of an expanding wild on the reels adds a layer of excitement as you eagerly watch to see if it will lead to a big win. This results in more dynamic gameplay, as these symbols add an additional layer of unpredictability.

Visual Appeal

Usually, expanding wilds come with eye-catching animations and graphics, along with exhilarating sounds which make your gaming experience even more enjoyable.

Disadvantages of Expanding Wilds

Of course, expanding wilds have their drawbacks too, so here we will list the most significant ones.

Increased Volatility

A common aspect of the expanding wild slots is that they are highly volatile, meaning that your winnings can be more substantial but less frequent.

Potentially Lower Base Game Payouts

In some cases, the presence of expanding wilds and other special features may result in lower payouts for regular symbol combinations in the base game. This trade-off can be worth it if you seek more significant wins through special features but may be less attractive to those who prefer more consistent, smaller wins.
