Fishing Trawler plays on a standard 5x3 reel set with 243 ways to win. Symbols include card royals alongside various sea life and fishing equipment. Wins are formed by matching symbols across adjacent reels starting from the left. The base game focuses on landing these combinations while waiting for the special bonus features to trigger.

The feeding frenzy bonus is activated by landing a full stack of fish symbols on any reel. During this feature, only fish symbols appear for 3 spins while independent multipliers on each reel increase with every catch. This high volatility title suits players who prefer chasing larger potential payouts through specialized bonus mechanics rather than frequent small wins.
