Bonus Features Deep Dive
1. Cascading Reels & The Cave-In
- Mechanic: Winning clusters are cleared away, causing a "cave-in" where new symbols fall from above.
- This can create chain reactions of wins from a single spin.
2. Dynamite Wild Explosions
- Trigger: A Dynamite Wild is part of a winning cluster.
- Mechanic: After the win is paid, the wild explodes.
- Effect: The blast removes all symbols in a 3x3 area around it, triggering a massive cascade and potentially hitting a Gold Nugget multiplier.
3. Prospector's Pick (Pick-Me Game)
- Trigger: Land 3 or more Bonus (Old Boot) symbols on the grid.
- Mechanic: You are shown a wall of 12 rocky outcrops.
Use your pickaxe to break open rocks and reveal prizes:
- Instant Cash Prizes (e.g., 5x, 10x, 25x bet)
- Multipliers (e.g., 2x, 3x) for your next spin.
- "Fool's Gold!" Ends the game but awards all collected prizes.
- Find the "Rich Vein" to win a major prize (100x bet) and end the bonus.
4. Deep Dig Free Spins
- Trigger: Land 3+ Scatter (Mine Elevator) symbols anywhere on the grid.
Awards:
- 3 Scatters = 8 Free Spins
- 4 Scatters = 10 Free Spins
- 5+ Scatters = 12 Free Spins
Locked Multiplier Nuggets:
- Before the round begins, 3 Gold Nuggets are placed on the grid, each with a random multiplier (x2, x3, x5).
- These multipliers are locked in place for the entire free spins feature.
- Any win that occurs on a reel with a nugget is multiplied by that nugget's value.
- If multiple nuggets contribute to a win, their values are multiplied together.
5. Lucky Strike (Random Feature)
- On any random non-winning cascade, you might get a lucky strike.
- Effect: Transforms all low-paying symbols on one reel into a high-paying gem.
