Since the base game of most slots revolves around making combinations of three or more symbols in order to land a payout, it’s easy to see why the Wilds are your friend. Scatter symbols are symbols that don’t need to line up in the same way as normal winning combinations in order to be activated when you play online slots. Typically, three or more scatters landing anywhere on the reels will activate a bonus, usually a Free Spins bonus, although not always. The Free Spins slots bonus works exactly as it sounds, with the player playing through a series of Free Spins once the bonus is triggered. Often, the Free Spins will also feature a win multiplier or some other element to amp up the online slot excitement further.
