In the beginning online slots were very simple. They had 3 reels, up to 8 pay-lines and a minimal number of features. The symbols were also simple and if a certain combination is triggered, you win credits. Nowadays online slots are a lot more complicated and come with all kinds of extras. In particular, they come with bonus games of different complexity, free spins, the opportunity to gamble your winnings including a jaw dropping progressive jackpot. The purpose of this article is to examine and explain the free spins feature found in almost every video slot on the Internet.

Free spins, as the name implies, are spins of the reels of a slot that you don’t have to pay for. Depending on the slot they are triggered in different ways. A frequent way of activating the free spins is by hitting three or more scatter icons anywhere on the reels. This is the simplest version of a bonus game in slots. In addition, the free spins rounds can also be retriggered in some games if you get three or more scatters while the spins are being played.

Furthermore, the free spins options in online slots might be part of a bonus game. For example, in a Pick Me feature you choose from several items to reveal your prize. The prize can range from free spins, extra wilds to multipliers. In addition, in most cases, the free spins are also attached a win multiplier of a certain value. This adds to their winning potential. Regardless of the ways they are triggered, the free spins can be very generous and everything you win from them is added to your total winnings.
