Free spins (aka Free Games) refer to a feature of more recent slot games. Usually 1 spin of a slot game, whether it’s mechanical or video reels, costs money or as we call, a bet. However, in certain games, if a certain game condition is met, a number of free spins will be rewarded to the player. Some games offer extra bonus features to the free spins so that the player has a higher chance of winning big during these free spins.
Example: The popular game 88 Fortunes by Shufflemaster. In this game, if the Free Spins feature is triggered by 3 scatter symbols, then the player is awarded 10 free spins. On top of that, during the 10 free spins, all the lower value symbols disappear from the reels, so the player has a higher chance of getting one of the higher symbol wins throughout all 10 free spins.
