Play 4 Wolf Drums Slot by 3 Oaks Gaming for Free

4 Wolf Drums by 3 Oaks Gaming places three colour-coded Drum Meters above a 5x3 wilderness grid, each filling as matching Bonus symbols land. Triggering a drum fires up to three features: Grab sweeps all on-screen values, Multi drops multipliers into empty cells, and Mirror expands the layout to 5x5 while duplicating symbols. A Master Drum can strike at any moment to refill empty positions. Four fixed jackpots and a Royal Jackpot worth 5,000x complete the bonus.
