In the context of slot machine gambling, the term free spins refers to the most common type of bonus game. This round gives players the ability to spin the reels on the maximum number of paylines without having to pay for the bet.
Sometimes the free spins will feature additional mechanics that either make it easier for the player to win or make the prospective winnings bigger.
The free spins bonus round is typically triggered when 3 or more scatter symbols land on the reels. In many cases, the number of free spins a player gets is directly proportional to the amount of scatter symbols that have triggered the round. For example, in Play’n GO’s Wild Rails, getting 3 scatter symbols will award you 5 free spins, 4 scatters will give you 7 spins, and landing all 5 scatters on the reels will award you 10 free spins.
