Bob Marlin Goes Deep

Bob Marlin Goes Deep is an underwater-themed video game from Yggdrasil, where the player dives into the depths of the ocean to catch valuable catches. The game starts with 5 reels and 4 rows, and there are 1,024 ways to win, but the reels can expand up to seven rows, allowing for up to 16,807 ways to win. The expansion occurs when bonus symbols (scatters) appear on reels 1, 3, or 5 – each of them adds a row during the respective spin.

The theme of the game is fishing, with a focus on colorful fish and maritime symbols. A central feature is the "Collectible Fish" system: when the reels have been expanded, fish symbols in various colors can appear, and five fish of the same color fill up a collection, activating the Collection Free Spins feature.

There are two different free spins modes in the game. The first, "Regular Free Spins," is activated when three or more bonus symbols are obtained – the player receives ten free spins with fully expanded reels (5x7), but without scatters or collection fish.

The second mode is Collection Free Spins, which is triggered based on collection tools. When five fish of the same color are collected during the base game's expansions, the player is awarded five free spins, where super high-paying symbols of the corresponding fish color appear.

Wild symbols are not part of the game, and there is no option for bonus buy. Bets start at low levels, and there is a reasonable upper limit; the game's volatility is low, meaning that wins are achieved more often, but they are generally smaller. The max win can be up to 3,905 times the bet.

You can try it for free in demo mode or play it for real money.
