The maximum reward is an impressive 3,905x the bet.
This video slot consists of 5 reels, 4 to 7 rows, and an initial 1,024 ways to win, expandable to a maximum of 16,807. Players can place bets starting from 0.1 up to 125. The game has a default RTP of 96.80%, with a lower variant of 90.50% available for some operators. It is characterized by low volatility and an expected base hit frequency of 20.67%.
The game incorporates valuable features such as Expanding Reels, Collections, Free Spins, and Collection Free Spins that can enhance the player experience.
The main setting of the game features clear turquoise waters, with most of the screen occupied by a wooden-framed mechanism held together by thick ropes. A fishing net stretches across, serving as a landing space for symbols. Bob the fisherman stands ready on the right, gripping the lever to activate the machine. Winning combinations require at least three matching symbols (or two for Super High Paying ones) on adjacent reels, starting from the leftmost reel. Thanks to its responsive design, players can enjoy the game on various devices, including desktops, smartphones, and tablets.
The paytable features three distinct sets of regular symbols. The low-paying symbols comprise royal letters from playing cards: J, Q, K, and A, which award 0.6x the bet for a five-of-a-kind hit. High-paying symbols include various fishing items, such as a can of worms, a lure, a fishing reel, and a tackle box, with prizes ranging from 0.8x to 1.4x the bet for five matching symbols. The Super High Paying symbols take the form of fish on golden tiles, appearing only during free spins and paying between 2.8x and 4x the bet for complete sets of five. In addition to regular symbols, the reels may occasionally display Bonus Symbols represented by a fishing boat and Collectible Symbols that contribute to progress towards special free spins.

The maximum win is up to 3,905x the bet.
What features are available in the slot Bob Marlin Goes Deep?
The game includes the following features: Expanding Reels, Collections, Free Spins, and Collection Free Spins.
Every Bonus symbol that lands in the playing area expands the grid by adding an extra row. The maximum grid height is 7 rows.
Next to the grid, there are four collection meters. Each meter requires five units of the respective fish to complete the progress. Collectible symbols can only appear on the additional rows created by the Expanding Reels feature.
Landing three Bonus symbols in a single spin activates 10 free spins, played on a fully expanded 5×7 grid.
Completing any meter triggers 5 Collection Free Spins, played on a fully expanded 5×7 grid with one active Super High Paying symbol type.
In a market flooded with fishing-themed slots, a unique approach is essential to stand out in this genre. While some titles like Big Bass Bonanza have the advantage of familiarity, new releases need to differentiate themselves. In the case of Bob Marlin Goes Deep, Yggdrasil seems to have missed an opportunity to creatively blend themes of Rasta culture and fishing suggested by the title. Despite hints of uniqueness in the title, players are presented with a conventional bearded fisherman in a rather uninspiring environment. While features like grid expansion add some dynamism, the overall gameplay remains unexciting.
The gameplay primarily revolves around occasional grid expansions where special fish symbols can appear, yet the paytable is relatively modest, leading to lackluster wins. Upon completing a collection, a free spins round offers one Super High Paying symbol, which, while beneficial, does not drastically enhance potential winnings compared to regular symbols. The only redeeming quality is the slightly above-average RTP of 96.80%.
Ultimately, Bob Marlin Goes Deep presents a rather shallow experience rather than an exhilarating deep-sea adventure, marked by a generic theme and uninspired gameplay.
