Mechanics
Set deep underground, connect clusters of 5+ matching symbols on the 7x7 grid to unearth maximum wins of 10,000x.
In the base game, when a dynamite-themed bonus symbol is visible at the same time as a winning combination anywhere on-screen, the symbol turn into a nugget – either bronze, silver, gold, or diamond. These nuggets remain on the reels for the remainder of the tumbling sequence, randomly awarding a win from a range of values depending on its type. Each time it pays, the nugget also collects a point, with three points upgrading the nugget’s type unless it is already diamond.
Land 3-7 bonus symbols to trigger the feature with 8-20 free spins. Each bonus symbol turns into a random nugget and remains sticky for the entire feature. Further bonus symbols that land at the same time as a winning tumble also transform into sticky nuggets and award two additional free spins.
What to expect:
- Landing three or more bonus symbols triggers the free spins round, awarding a maximum of 20 spins.
- During the feature, bonus symbols turn into random nuggets and are sticky throughout free spins.
- For every new mine created in the feature, a further two spins are awarded.
