Let’s see what’s swimming beneath the surface.
Reel Setup and Slot Stats
At its core, Bob Marlin Goes Deep starts with:
- Reels: 5
- Rows: 4 (expands to 7)

- RTP Options: 96.8%, 94%, or 90.5%

Visuals and Theme
The tone is fun, friendly, and cartoonish. Bob Marlin, a fishing enthusiast with a big beard and even bigger ambition, anchors the game’s personality. The background is a peaceful ocean floor, and the reels are filled with colorful fish, sea gear, and quirky aquatic animations.
It’s a relaxing trip under the sea, paired with a bouncy soundtrack and gentle visual flourishes. Nothing too flashy, but it gets the job done.
Expanding Reels and Base Game Features
The base game is far from static. Landing Scavenger Scatter symbols on reels 1, 3, or 5 triggers reel expansion, adding one new row per scatter, up to a maximum of 7 rows. This naturally increases win potential as more rows = more ways to win.
Once fully expanded, the game hits its top win configuration: 5×7 with 16,807 ways to win.
Free Spins and Bonus Mechanics
Bob Marlin Goes Deep has two main bonus features:
- Standard Free Spins
- Triggered by landing 3 Scavenger Scatters
- Awards 10 Free Spins
- Played on the fully expanded 5×7 grid
- No scatter or collectible symbols appear here
These are straightforward spins with no special modifiers—but they benefit from the max number of winways.
Fish Collection Free Spins
This is where things get more engaging.
- Collect 5 matching colored fish (on expanded reels)
- Triggers 5 Collection Free Spins
- Each fish color is linked to a high-paying symbol
- Only that fish’s color/symbol appears during the feature
You can trigger multiple collections, and they’ll play out sequentially in color order: Blue, Green, Purple, Orange.
Payouts and Symbols
While base game wins are on the modest side, the collectible fish features help spike the excitement.
- Regular symbols: pay up to ~1.4× for five-of-a-kind
- Super high-paying fish: pay up to 4× for five-of-a-kind
- No wilds or multipliers in the game, which might disappoint more feature-hungry players
Final Thoughts
Bob Marlin Goes Deep is a great catch for players who enjoy chill, feature-light slots with a twist. The collectible fish mechanic adds a unique flavor, and the expanding reels keep the base game fresh. It’s definitely not for adrenaline junkies or fans of mega wins, but it swims comfortably in its own low-volatility lane.
If you’re looking for a casual dive with steady payouts, Bob Marlin’s your guy.
