In the base game whenever a WILD symbol hits, a random number of WILDS are added to the screen in random positions.
Hit 3 SCATTER symbols to trigger the feature and get 8 free spins.
During the FREE SPINS feature each SCATTER symbol is collected in a meter.
Every 3rd SCATTER symbol collected, the feature is retriggered, 5 free spins are awarded and a random WILD symbol is added to the screen in a random position. The added WILD remains on the screen until the end of the round.
Special reels are in play during the feature.
