Jack Hammer's primary bonus feature is the innovative Sticky Win mechanism that activates on every winning combination:
Sticky Win Feature: • All winning symbols lock in position • Non-winning positions re-spin automatically • New winning symbols also become sticky • Process continues until no new wins occur • Total winnings paid out at sequence end
This feature applies to both regular symbols and free spin scatters, making it easier to accumulate the scatter symbols needed for the main bonus round. The Sticky Win mechanic significantly increases your chances of extending winning sequences and building substantial payouts.
The free spins feature in Jack Hammer activates when you collect 5 or more scatter symbols simultaneously on the reels:
Free Spins Award Structure: • 5 scatters = 10 free spins • 6 scatters = 15 free spins • 7 scatters = 20 free spins • 8 scatters = 25 free spins • 9-15 scatters = 30 free spins (maximum)
Bonus Features: • All wins receive a 3x multiplier • Sticky Win feature remains active • Maximum potential of 3,000x your stake
The Sticky Win mechanism makes accumulating multiple scatters more achievable, as scatter symbols lock in place during re-spins, increasing your chances of triggering substantial free spin sessions.
While Jack Hammer doesn't feature a progressive or fixed jackpot, it offers impressive win potential for a low volatility slot:
Win Potential: • Maximum payout: 3,000x your total stake • Achieved during free spins with 3x multiplier • Top prize potential: £750,000 at maximum bet • Consistent smaller wins due to low variance
