Twisted Sister is a high-voltage 6x6 grid slot inspired by the iconic 80s rock band. The game uses a cluster pays mechanic, where wins are formed by groups of matching symbols and cascading reels replace winning combinations. Players can charge up the 'Anger Meter' by landing winning clusters, unlocking band member features that modify the grid. A 'We're Not Gonna Take It!' free spins round awaits, offering explosive wins with Guitar Charge Wilds and multiplier bombs.
