About this Slot
BOOMSHAFT is a mining-themed slot from Bad Habit with an RTP of 96%, high volatility and a maximum win of 10,000x. The game features five reels, four rows and 1024 Ways to win.
The Wild Drill symbol substitutes for all regular symbols except the TNT Scatter. When five Wild Drill symbols land across the reels, the symbol pays on its own.
TNT Scatter symbols trigger the bonus via a scatter ladder system. Cascading Reels activate after wins, with a multiplier that starts at x1 and rises with each successive win.
BOOMSHAFT mode plays on a 5x4 board with boosted Wild Drill frequency. The bottom row destroys after each cascade, creating additional winning opportunities.
Boomshaft Extended expands the board to 5x5 and requires four Scatter symbols to trigger. This mode offers boosted Wild Drill frequency and a growing multiplier across cascades.
Hidden Bonus triggers when five Scatter symbols land or via the buy option. TNT clusters drop onto the board before free spins begin.
Extra Blast doubles the cost of a standard bonus buy and triples the chance of triggering the feature.
Deep Mine costs 5x the base stake and grants one paid 5x5 spin.
TNT Frenzy costs 100x the base stake and provides one paid 5x5 spin where random TNT clusters explode before cascades begin. Symbols covered by TNT clusters become Wild Drill symbols.
Dig for Hidden costs 500x the base stake and awards a random feature.
