Circle of Life

Wheel of Fortune is a bonus game styled after a TV show's 'prize wheel', where the player spins a large wheel divided into multiple segments to win the prize indicated by the pointer when it stops. This feature is simple yet allows for very dramatic presentations, which is why it is very frequently used as a method for determining the winner of a progressive jackpot.

A Retrigger means winning additional free spins by landing scatter symbols again during a free spins bonus round. Furthermore, some slots adopt an 'unlimited retrigger' system, which means there is no limit to the number of times it can re-trigger. In theory, if luck is on your side, the free spins can continue indefinitely, making it one of the most powerful features a slot can have.
