Free Slots with Wild Symbol

The slot machine wild symbol is described as the generous symbol, as its primary function is to substitute any other symbol on your reels. Let’s say you land a BAR on reel 1 and reel 3, and the wild on reel 2, this symbol will count as a BAR for that round and deliver a win. So in layman's terms, your wild is the random filler that increases your winning potential in online slots.

The only symbol it does not substitute is the scatter. Always make sure on your paytable, which is the wild, and which is the scatter. The wild can also randomly award you with a bonus payout, but that is determined by the individual developers and not a set standard in all games.
