Free Spin Slot Machine Bonus Features

The free spin slot machine bonus feature is the most popular type of slot machine bonus.
Once the feature is triggered ( often when three scatter or bonus symbols appear on the slot machine reels ) the slot machine player is granted an amount of free spins on the slot machine.

The basic free spin bonus feature simple spins the slot machine a number of times and adds the wins to the players online casino account. Fortunately, most online casinos have slot machines with more impressive free spin bonus features.

The most common version of the free spin bonus feature is the multiplication bonus.
Slot machines with free spin winning multipliers double or tripple the wins during the free spin bonus feature.
Some slot machines have random winning multipliers and allow for up to 18 x wins during lucky spins.

Another fairly common version of the free spin bonus feature is the extra wild feature.
This version of the free spin bonus feature is played with more wild symbols on the game reels than during normal spins. Sometimes they bonus or scatter symbols are removed and are replaced with wild symbols.

Most slot machine free spin bonus features have a re-trigger option. This means that the free spin bonus feature can be re-triggered during play. If you win 10 free spins, and the bonus occurs again during the free spins, you gain an additional 10 free spins that are played during the same bonus session.

Some free spin bonus features have special bonus symbols that increase the amount of free spins during play or even the multiplier.

You will quickly discover the vast amount of different free spin bonus features available at the online casinos when you start playing.
