Bob Marlin Goes Deep

Bob Marlin Goes Deep takes Yggdrasil's fisherman hero below the surface, trading open water for a deep-sea descent where collecting colored fish unlocks a special free spins mode built around a single premium symbol type. The 5x4 grid starts with 1,024 ways to win, but the reels grow to 5x7 during the Collection Free Spins, pushing ways to 16,807 and concentrating the action on whichever fish you gathered. With a 96.8% RTP, medium-high volatility, and a max win of 3,905x, the game suits players who enjoy a structured collection mechanic over instant volatility spikes. It plays smoothly on desktop and mobile, and you can try it in demo mode before playing with crypto.

What is Bob Marlin Goes Deep?

Bob Marlin Goes Deep is a 5x4 video slot from Yggdrasil with a 96.8% RTP, medium-high volatility, and a top win of 3,905x your bet. Its standout mechanic is a color-coded fish collection system that determines which super-high-paying symbol fills the expanded 5x7 grid during free spins.

The base game plays on 1,024 ways to win, with four tiers of paying symbols and a scatter that triggers 10 free spins on the fully expanded grid. What separates this game from a standard free-spins slot is the Collectable Fish Feature: landing colored fish (Orange, Blue, Green, Purple) in the base game builds a meter, and banking 5 of any color earns 5 Collection Free Spins where only that fish type and the wild appear, making the payouts considerably denser than a mixed-symbol board.

Who will enjoy this game the most?

You will probably enjoy this game if you like:

• Players who prefer medium-high volatility with a structured reward path rather than pure luck of the spin
• Fans of expanding reel mechanics where the grid grows to maximize ways to win
• Anyone who enjoys collection or progression systems that build toward a dedicated bonus round
• Crypto casino players after solid RTP (96.8%) on desktop and mobile
• Those who like themed slots with a coastal or underwater setting

3. Land 3 or more scatters anywhere to trigger 10 standard free spins on the expanded 5x7 grid with up to 16,807 ways to win
4. Bank 5 fish of the same color to unlock 5 Collection Free Spins, played at the average bet from your collection run with only that fish type as the premium symbol

Bob Marlin Goes Deep Slot Theme & Graphics

The game continues Yggdrasil's Bob Marlin series but swaps the familiar surface setting for a deep-ocean environment. The reels sit against a dark aquatic backdrop, lit by bioluminescent hues of blue and green. Bob himself is a cheerful presence at the edge of the screen as fish drift through the background.

Symbol art follows the underwater-fishing kit theme: tackle box, fishing reel, lure, and worms fill the mid-tier positions, while the four collectible fish (Orange, Blue, Green, Purple) arrive in cartoon style with expressive detail. The expanding reel animation as the grid stretches to 5x7 is one of the cleaner transitions in the series, and the mobile version scales the grid proportionally so nothing feels cramped on a smaller screen.

Bob Marlin Goes Deep Slot Symbols & Paytables

The symbol set divides across three tiers: low-pays are classic card royals, mid-pays are fishing equipment, and the super-high-paying fish only appear during the Collection Free Spins mode. Understanding which symbols show up when is the key to reading the paytable.

Low Value Symbols

Card royals (J, Q, K, A) fill the low-value positions. They land frequently on every spin and form the base of most winning combinations, paying 0.6x for a five-of-a-kind line. They exist mainly to keep the hit frequency alive between the more valuable fishing-theme wins, and they are absent from the Collection Free Spins reels, which strips them out to sharpen the focus on premium symbols.

High Value Symbols

Worm, lure, fishing reel, and tackle box make up the mid-tier group. These pay between 0.8x and 1.4x for five on a line, providing meaningful wins in the base game and standard free spins. They appear across the full 5x4 base grid and on the expanded 5x7 during regular free spins, though like the royals they do not appear during Collection Free Spins.

Special Symbols

The four collectible fish (Orange, Blue, Green, Purple) are the super-high-paying symbols, worth 2.8x to 4x for five on a line in standard play. Their real purpose is the collection mechanic: five of any single color banked in the base game earns 5 Collection Free Spins where only that color fish appears on the fully expanded grid. The scatter lands the standard free spins trigger at 3 or more anywhere in view.

Bob Marlin Goes Deep Bonus Feature & Special Features

Collectable Fish Feature

Throughout the base game, colored fish symbols (Orange, Blue, Green, Purple) land on the reels and populate a collection meter divided into four color tracks. Each fish that lands increments the corresponding color counter. When any single color reaches 5 fish, the player banks those and triggers 5 Collection Free Spins. These spins are played at the average stake placed during the collection period and on the fully expanded 5x7 grid with 16,807 ways to win. Critically, only the collected fish type appears as a premium symbol during those spins, so the paytable is concentrated rather than diluted across four fish types plus equipment symbols. This makes Collection Free Spins the most lucrative mode in the game and rewards consistent base-game play rather than a single scatter-driven trigger.

Free Spins (Scatter Trigger)

Landing 3 or more scatter symbols anywhere on the 5x4 grid awards 10 free spins on the fully expanded 5x7 layout with up to 16,807 ways to win. The expanded rows materially increase the number of symbol positions in play, so wins per spin are generally larger than in the base game. All symbol tiers are present during these spins, meaning the fish collection mechanic continues to operate, and any fish banked during free spins contribute toward future Collection Free Spins. Retriggers are possible by landing additional scatters during the feature. This is the more accessible bonus path compared to the collection route, and both modes benefit from the expanded reel set.
