Gemstones in various colours litter the rock surface.There are 8 regular symbols in this slot game that pay when 3 more symbols land in consequence reels, starting from the left.

This feature makes room for more symbols to drop down into new positions. The symbols of a winning combination explode and the symbols above them fall into place. New symbols drop down from the top, giving the player another chance to win. New symbols continue to drop down until there are no more winning combinations. 4 or more identical symbols can drop in a square formation, but each symbol functions as individual symbol.


This feature is activated after 2, 5, or 9 consecutive drop down wins occur. The Gem Rock feature guarantees a win. A single Monster rock made up of identical symbols is awarded during the Gem Rock feature. Up to 9 consecutive wins can be recorded on the Gem Meter (gargoyles). After the 9th consecutive wins, no more wins can be recorded until the Gem Meter is reset by missing a consecutive win. The more consecutive wins a player lands, the larger the Gem Rock. The size of the Monster rock increases in the following way:

2 Consecutive wins in a row = 2*2 Monster Rock

5 Consecutive wins in a row = 3*3 Monster Rock

9 Consecutive wins in a row = 4*4 Monster Rock
