About this Slot
Mad Machine is a Steampunk and Sci-Fi themed slot from Rat Hole Reels with an RTP of 96%, low volatility and a maximum win of 5,000x.
Winning clusters of matching symbols trigger cascading wins, with symbols tumbling down after each cluster removal to create further winning combinations.
Three or more Scatters anywhere on the grid trigger Free Spins. Landing additional Scatters during Free Spins retriggers the feature, adding more free spins to the total.
Bonus Hunt costs 5x bet per spin and boosts the frequency of Scatter and Switch symbol spawns. The feature runs continuously until you choose to switch it off.
Collecting four Switch symbols in a single spin triggers the Overcharge Chamber bonus round. This feature uses a separate symbol set and locks symbols into sockets, building value through matched symbol sequences.
20 Mega Spins can be purchased for 300x bet. This feature increases the spawn rate of premium symbols during the spins.
10 Free Spins are available as a direct purchase for 100x bet.
The Overcharge Chamber bonus can be bought directly for 200x bet, bypassing the need to collect four Switch symbols in base play.
