BOOMSHAFT

About this Slot

BOOMSHAFT is a mining-themed slot by Bad Habit with an RTP of 96%, high volatility and a maximum win of 10,000x. The game uses 5 reels, 4 rows and 1024 Ways to win, with cascading reels and a multiplier that builds during bonus rounds. Wild Drill substitutes for every regular symbol except TNT Scatter. It also pays as its own symbol when it lands on all five reels, giving it a dual role beyond simple wild substitution. TNT Scatter lands anywhere on the board and does not pay as a regular symbol. Instead, it unlocks bonus spins through a scatter ladder that reaches three different bonus modes. BOOMSHAFT starts when you land three TNT Scatter symbols or buy it directly. The feature plays on a 5×4 board with boosted Wild Drill frequency, and the bottom row is destroyed after each winning cascade. The multiplier begins at x1 and increases after every win. Boomshaft Extended triggers with four TNT Scatter symbols or through a direct purchase. This mode expands the board to 5×5, uses boosted Wild Drill frequency and row destruction cascades, and features a multiplier that grows with each winning cascade before resetting at the start of the next spin. Hidden Bonus starts when five TNT Scatter symbols land or via Dig for Hidden. The 5×5 board receives TNT clusters before every free spin, making this the most volatile bonus mode. Extra Blast is a paid feature that doubles the round cost and triples the natural bonus trigger chance. It does not alter symbol payouts or cascade rules. Deep Mine costs x5 and opens one paid 5×5 spin using the same ways and cascade rules as the feature boards, without triggering free spins. TNT Frenzy costs x100 and opens one paid 5×5 spin where non-overlapping TNT clusters between 1×1 and 5×5 land and explode before cascades begin. Covered symbols become Wild Drill symbols. Dig for Hidden costs x500 and randomly awards one of three features through a weighted result table.
