landing a Switch symbol triggers 1 to 10 respins in which randomly selected symbols are switched to the top-paying clown symbol or to Wilds; new Switch symbols add more switches and respins.
Wild
a stretching-hand Wild substitutes for pay symbols and is also the highest-paying symbol, paying 50x the bet for 6 on a payline.
Mad Scientist
3 Mad Scientist scatters award 10 free spins with an increased chance of Switch symbols; switched symbols reset after each spin.
Total Takeover
3 Total Takeover scatters award 10 free spins in which switched symbols stay switched for the whole round; 3 more Total Takeover scatters add 4 spins.
SwitchSpins chain: each Switch symbol converts random symbols to the clown or Wilds and adds respins, so a single trigger can grow into a long cascade. Total Takeover holds those conversions in place across all 10 spins rather than resetting each round.
