Bonus Features Deep Dive
1. Cascading Reels & The Polish Feature
- Cascading Wins: Standard cluster-pay mechanic.
- The Polish Feature: This is the core game mechanic. After any winning cascade that includes an Artisan's Hammer Wild, the Hammer strikes the grid.
- It randomly selects one adjacent symbol and "polishes" it, upgrading it to the next highest value symbol (e.g., a Rough Gem becomes a Flawless Diamond).
- This often creates a new, subsequent winning cluster, leading to a powerful chain reaction.
2. Masterwork Free Spins
- Trigger: Land 3, 4, 5, or 6 Masterwork Anvil scatters to award 8, 10, 12, or 15 free spins.
Special Rules - The Polish feature is enhanced. The Hammer now polishes 2 to 3 adjacent symbols after every cascade.
- The Heat Meter fills 50% faster.
- The progressive multiplier from the base game is active and does not reset between spins.
3. The Heat Meter
- A forge-themed meter on the side of the grid fills with every symbol in a winning cluster.
- At 100% - Temper: The entire forge overheats. All Low-Paying "Rough Gem" symbols on the grid are instantly upgraded to High-Paying "Flawless" symbols, setting up a guaranteed large win or a massive cascade sequence.
