The paysymbols that appear in view are oil lamps, shovels, gold nugget pouches on the low end followed by better-paying mine carts, game logo, wild, and a scatter.
The slot uses the so-called tumbling reels mechanics where the symbols that form a winning combination explode to make room for new ones that may form a winning combination as well. The feature ends when the symbols that appear on the grid do not form a winning combination.
Each winning cascade expands the grid and in the best-case scenario, you will play on a 5×10 grid. What’s more, each winning cascade adds points to the meter you see next to the grid. Once you collect the required number of points, you get extra wilds placed on the reels, a multiplier, or a mega wild appearing 2×2 in size.
Free Spins
Land at least 3 dynamite scatter symbols to get 8 free spins. Every extra scatter you land grants you 1 extra free spin. During the free spins round, the randomly triggered Rollercoaster Spins feature might come into play and award you 100 spins.
*At the time of writing, the Gold’n Rocks slot is yet to go live, but its launch is expected any moment now. It might already be playable across the best Microgaming casinos by the time you read this review, so it would not hurt to check them out.
