How does the Collapsing Mine work?
Each spin starts with 3 rows open. Wins collapse and new symbols drop in, opening more rows up to 6, which gives up to 46,656 ways.
- xBomb Wilds: stand in for every symbol except bonus symbols, then explode, removing the symbols next to them, adding +1 to the win multiplier and starting a new collapse.
- Wild Mining: 3, 4 or 5 matching symbols in a row that do not win award 1, 2 or 3 wilds and a collapse.
How do Lucky Wagon Spins work?
Three, four or five bonus symbols open 2, 3 or 4 extra rows and start the round with 3 spins. Every new coin resets the spins to 3. Minecarts above the reels drop enhancers such as coin values, multipliers, dynamite, bags, chests and the Dwarf, and coins can be worth up to x100.
