The reels are situated in the cloudy, greenish water of a Scottish loch. Each reel is separated by a line of moving bubbles, adding to the underwater aesthetic. At the bottom of the lake, players will see an ancient castle with schools of fish swimming among the towers. This enhances the sense of mystery around the loch.
Among the symbols are fishing rods, tackle boxes, colorful fish, and vibrant dragonflies. Lower-paying symbols take the form of stylized letters that evoke medieval texts.
The most memorable symbol is the Gold Ness Monster himself, with his long neck and gleaming golden scales. His large eyes and small smile suggest that he is not a monster that should be feared.

If the regular Free Spins feature is selected, each Fisherman Wild symbol collects all values from any Money symbols on the reels. Every 4th Fisherman Wild collected retriggers the feature, awarding 10 additional free spins and a multiplier that increases for each retrigger. The multiplier increases from 2x to 3x to 10x.
If the Gold Ness Free Spins feature is selected, the regular symbols disappear, leaving a grid where only Money symbols and Fisherman Wild symbols appear. The round begins with 10 free spins.
