The scatter symbol is the Grease logo and it is key to one of the main bonus features.
Bonus Features
On any spin the Sweetheart Wild Symbols Feature may be triggered and between five and eight extra wilds will be added to the reels to help you form loads of wins. Best of all, when it triggers, you are guaranteed a stacked wild.
If Danny, Sandy, or the Danny and Sandy symbol fills the first reel then the Rockin’ and a Rollin’ Respins feature begins. The reels will respin for free three times, and during the spins all wild symbols will lock into place. Furthermore, if the feature was triggered by Sandy then all Sandy symbols will lock, if it was triggered by Danny then all Danny symbols will lock, and if it was triggered by the Danny and Sandy combo then all three symbols will lock in place.
