01The grid and the lines
The game runs on 5 reels of 5 rows with 40 fixed paylines. Three, four or five matching symbols on a line pay from the leftmost reel. Low symbols are the 
anchor, 
compass, 
periscope and 
diving helmet; the high ones are four sharks — 
blue, 
green, 
pink and 
orange.
02The Great White Wild
The 
Great White substitutes for every paying symbol and pays the most on its own: 1×, 4× or 12.5× the bet for three, four or five.
03Mystery stacks: Nudge & Reveal
Mystery seaweed lands in stacks of five on any reel.- All Mysteries reveal the same thing: one paying symbol, a Great White Wild or a Golden Shark.
- On the next spin they drop one row and reveal again, until they leave the reels.
04Golden Sharks and Razor Reveal
When Mysteries become 
Golden Sharks, Razor Reveal starts. Each shark reveals an instant prize (1×–5,000×), a multiplier, a Collector, a Converter or a Torpedo. Details on the feature page.
