About this Slot
Big Boom Bonanza is a mines and gems-themed slot from Disco Koala with an RTP of 96.11%, high volatility and a maximum win of 5,000x. The game plays across 6 reels and 5 rows with scatter pays, meaning 8 or more matching symbols anywhere on the grid form a winning combination.
The Cascading mechanic removes winning symbols from the reels, allowing new symbols to fall and create chain wins from a single spin. During winning combinations, Dynamite multipliers ranging from 2x to 100x can activate to boost payouts.
The Detonator feature starts at 2x during bonus spins and accumulates Dynamite multipliers across spins. This accumulated value persists throughout the entire bonus round, growing with each triggering combination.
Landing 4 bonus scatters awards 10 bonus spins. Landing 5 bonus scatters triggers 10 super bonus spins, which guarantee a Detonator on the first tumble. Collecting 3 extra bonus symbols during the feature grants 5 additional spins.
Four bonus buy options allow direct access to bonus features. Chance Enhancer costs 5x the bet and improves the odds of triggering bonuses. Guaranteed Dynamite costs 20x the bet and ensures Dynamite activation. Bonus Spins costs 100x the bet to launch the main bonus round. Super Bonus Spins costs 200x the bet and awards the enhanced super bonus spins feature.
