Main Mechanics
The cascading reels system removes winning combinations from the grid. New icons fall into empty spaces to create more wins. This process continues until no new matches form. Each cascade happens within the same spin and adds to the total payout. Mining carts roll across the top of reels 2, 3, 4 and 5. These carts carry extra symbols that drop onto the main grid. The additional icons increase the height of reels and create more ways to win. Some spins produce up to seven symbols on a single reel. The free spins round starts when four scatter letters spell GOLD. Players receive 12 bonus spins with unlimited win multipliers. Each cascade during free spins increases the multiplier by one. Extra scatters award five more spins per set of four letters.
Multipliers and Bonuses
Wild dynamite sticks substitute for all regular icons except scatters. These elements appear on reels 2, 3, 4 and 5 only. The mystery symbol appears as a TNT barrel during regular spins. All mystery icons on screen transform into the same random symbol. This transformation happens after the reels stop but before wins calculate. The game includes several bonus features:
- Reactions Feature – Winning icons explode and new ones drop down
- Mystery Symbols – Transform into matching icons after landing
- Free Spins Multiplier – Grows with each successful cascade
- Scatter Retrigger – Adds five spins for every four GOLD letters
- Maximum Win – Reaches 10,000 times the stake
