About this Slot
Dr. Clanker is a horror, sci-fi and steampunk-themed slot from Energi with an RTP of 96.1%, high volatility and a maximum win of 40,000x. The game features 5 reels, 4 rows and 1024 Ways to win.
Cascading reels cause winning symbols to drop away, allowing new symbols to fall and potentially trigger further wins in a single spin. A battery mechanic tracks consecutive winning tumbles, charging one cell per win. When fully charged after three consecutive wins, the battery doubles the active multiplier, then resets following the next non-winning tumble or base game spin.
Procedures are random events triggered by either a fully charged battery or a non-winning tumble. These events transform the board without affecting scattered Specimens.
Three or more Specimens scattered across the board unlock Free Spins, awarding 10 spins at a x1 multiplier. Four Specimens trigger Super Free Spins, which award 10 spins at a x4 multiplier. Five Specimens open The Pit, granting 5 spins at a x32 multiplier and guaranteeing a minimum win of 500x.
During free spin rounds, landing 3, 4 or 5 additional Specimens awards 5, 7 or 10 extra spins respectively. The Basement preserves the active multiplier throughout the entire bonus run, with Free Spins occurring on B1, Super Free Spins on B2 and The Pit on B3.
Power Surge increases both the frequency of Specimen scatters and Procedure triggers. Live Wire forces two Procedures during the first two dead tumbles within a single spin.
Buyable Free Spins grant 10 spins at x1 multiplier. Buyable Super Free Spins grant 10 spins at x4 multiplier. Mystery Bonus randomly sends players to either Super Free Spins or The Pit.
