As from the name, the Expanding Wild in a slot game is something that can have the powers to “expand” and take up more spaces. In this case, it will be a Wild symbol that will grow on the reel grid and cover up all the other symbols to make more entry for substituting winning combinations.
As with any bonus feature, there are multiple ways in which you can activate the Expanding Wild in the slot game. For example, it may be unlocked through the use of another bonus feature like a Free Spins round or it may appear randomly on the reel grid. It may grow bigger and bigger with each spin or stay as that size for a prolonged time.
An Expanding Wild symbol may occur in a slot game to give you guaranteed chances of winning. Since you can win with a regular Wild, an Expanding Wild can just offer plenty of more options in the next spin. Another bonus feature may cause it to expand in numerous ways, allowing you to control the next spin with ease.
Expanding Wild is simply a Wild symbol but now with more of it, creating better opportunities for you to score in a slot game with more substitutions.
The Wild symbol may also be the biggest payout in the slot game, meaning that by expanding it, you now have better chances of getting the biggest prize on the reel grid. If not, it may take up more space for better symbols you may have been able to land.
The Expanding Wild may also be combined with another bonus feature to give you more winnings in the slot game.
