On random spins a symbol can be randomly chosen to split into two. All instances of that symbol will then split. Any symbol can split except Scatter. Mystery Symbols can also land on any spin. They reveal matching symbols of any type except Scatters. On the random spins the Rumble Row reel modifier will activate above the reels. This can award various features to the reel below it. The Wild Reel will land a full reel of Wilds. Double Trouble will sync the symbols on that reel with the reel before it. X2 Multiplier will award a x2 Multiplier to all wins from that reel.
