In addition to wins using only standard symbols, online video slots feature a wide array of bonus icons and rounds, which improve a player’s chance of success, while also adding some variety to gameplay. The most commonly used slot game bonus features include Scatters, Wilds and Multiplier bonuses.
Scatter symbols are icons that do not necessarily have to appear on the payline in order to be activated. In most online video slots, the appearance of three, four or five scatter symbols spread out across the reels will generate a bonus payment, or even launch a bonus round or free spins round.
Wild symbols act as chameleons and can be substituted for other icons, which can help turn a losing line into a winning one. It's worth bearing in mind, though, that wild symbols are not usually able to replace a scatter symbol.
Multiplier bonuses rounds can take various forms, but ultimately lead to a player trying to progress through several rounds in order to increase their score. This is often then multiplied by the initial bet to reward a much higher cash prize.
