How the Game Plays

Bob Marlin Goes Deep takes you on a bright, aquatic excursion featuring the titular fisherman and his automated netting system. Unlike standard fishing slots that typically use "Collect" mechanics, this Yggdrasil Gaming title centers on a dynamic grid that expands when bonus symbols appear. The base game begins on a 5x4 grid with 1,024 ways to win, where matching symbols pay from left to right. When scatters land on the first, third, or fifth reels, the grid adds additional rows at the bottom for that spin, potentially reaching a 5x7 layout with 16,807 ways to win.

Free Spins Explained

There are two ways to experience free rounds in this slot. Landing three scatter symbols in the base game triggers 10 standard Free Spins, which are played on the fully expanded 5x7 grid for maximum winning potential. Separate from the scatter-driven bonus, players can also trigger Collection Free Spins. By filling color-coded meters with matching fish symbols that appear on expanded rows, you unlock 5 specialized spins. These rounds use the full 5x7 grid and feature super high-paying versions of the collected fish, which award wins with as few as two matching symbols on a path.

Expanding Reels Explained

The core of the experience lies in the reel expansion. Every time a scatter symbol lands on an active reel, it adds one extra row to the playing area. Up to three additional rows can be unlocked in a single spin. These extra rows are the only place where collectible fish symbols appear, making the expansion mechanic essential for progressing toward the higher-value collection bonuses.
