Our article dives into Yggdrasil’s new fishing adventure Bob Marlin Goes Deep, explaining its expanding-reel mechanic, 16,807 ways, low volatility gameplay, dual RTP settings, and why Canadian players may prefer its steady 3,905× max win over riskier fish slots.
Uniqueness Compared to Previous Fishing Slots
Bob Marlin Goes Deep splashed onto Canadian lobbies on 24 July 2025 as the first in-house fishing slot from Yggdrasil in almost five years. Earlier wet-and-wild efforts, Golden Fish Tank 2 and 4ThePlayer’s partner release 4 Fantastic Fish, relied on cash-collection hooks or scatter pays. Bob steers a different boat. The core loop is reel expansion plus fish collections, not money symbols, so wins feel steadier and more base-game driven. Yggdrasil’s official sheet confirms the game sits in the low-volatility class with only two RTP configurations and a capped 3,905× multiplier, again diverging from volatile “hook and pay” rivals.
Expanding Reels and 16,807 Ways in Bob Marlin Goes Deep
Every scatter that lands on reels 1, 3, or 5 adds a bottom row for that spin. The grid can stretch from 5×4 to 5×7, lifting paths to 16,807 ways. Rows reset between paid spins, so pacing stays lively and light on bankroll. Reviewers call the mechanic “consumed by Expanding Reels,” noting three scatters in one drop unlock instant full height.
Below you see the way size changes affect hit potential.
| Grid Size | Rows | Ways to Win | % Increase from Base |
|---|---|---|---|
| 5×4 | 4 | 1,024 | – |
| 5×5 | 5 | 3,125 | +205 % |
| 5×6 | 6 | 7,776 | +660 % |
| 5×7 | 7 | 16,807 | +1,542 % |
More rows mean extra fish symbols can land, fuelling the meters we cover next. The table highlights why patient expansion spins matter. Two or three added rows multiply line potential far beyond classic 1,024-way formats.
Payout Boosts from Four Fish Meters
Bob tracks four coloured fish, blue, green, purple, orange, beside the reels. Catch five of a kind and you trigger five Collection Free Spins on the full 5×7 board. During that mini-bonus, only one “super high” fish symbol appears, paying 2.8× to 4× for five of a kind and just two needed to start a line.
Players begin with three pre-collected orange fish, trimming grind time. When multiple meters fill together, they fire in blue-green-purple-orange order, a detail that matters if you crave the 4× red fish first.
Low Volatility with 3,905× Max Win
Yggdrasil pegs variance as “Low,” rare for a modern fish slot that still flirts with a 3,905× ceiling. Canadian casuals who favour longer entertainment over extreme spikes can finally fish without white-knuckle swings. A capped jackpot under 4,000× may deter adrenaline chasers, yet a steadier hit frequency, 20.67 % in demo audits, keeps small-to-mid wins flowing.
Critics, Streamers, and Ratings
Early reviews hover around the middle of the lake. Scores praise the fair RTP but call visuals “not the most eye-catching.” Some verdicts have been blunter, comparing the end flavour to “a soggy fish finger.”
Still, Twitch streamers like CasinoDaddy clipped 450× base-game hits within the first week, sparking a community challenge, collect all four fish on a single €1 spin. Anecdotal buzz suggests Bob will slot into variety rotations rather than headline high-risk marathons.
Super High Pay Symbols
The paytable uses three tiers. Super High symbols are framed gold fish that unlock only in Collection Free Spins and pay from two matches. High symbols are tackle-box gear paying up to 1.4×. Low symbols are card royals capped at 0.6×.
- Collection Meter: Tracks up to five identical fish.
- Super High Pay: Fish active during Collection Spins.
- Bonus Symbol: Boat steering wheel scatter that expands reels.
Knowing the jargon avoids confusion when Bob shouts “Big Catch!” but your meter stays empty—he is celebrating a scatter, not a fish.
Bet Sizes and Patience Strategies
Bob accepts wagers from $0.10 to $125. Low volatility tempts many to crank stakes quickly, yet tests show average meter completion every 90-110 spins at minimum bet, doubling stake shortens the grind only marginally.
Consider this three-step bankroll plan before diving in:
- Start at 100× session bankroll divided by 300 spins.
- Raise one unit after each Collection Spin set, never before.
- Drop back if two full grids expand without any fish catches.
This approach stretches entertainment and positions you for potential bonus offers without busting early.
Comparing Bob Marlin to other slots
A quick side-by-side puts Bob in context.
| Slot | Volatility | Max Win | Core Feature | RTP Top |
|---|---|---|---|---|
| Bob Marlin Goes Deep | Low | 3,905× | Expanding reels + collections | 96.8 % |
| Fishin’ Pots of Gold (YGG) | Medium | 10,000× | Pot-collection multipliers | 96.0 % |
| Big Bass Bonanza 1000 (PP) | High | 20,000× | Fisherman cash collector | 96.1 % |
Bob sits below on potential but above on stability. For Ontario players chasing a mellow session after work, his profile trumps the roller-coaster of high-volatility favourites like Big Bass.

Yggdrasil supplies two maths models. Picking the wrong lobby slashes playtime by more than 70 %. Always open the paytable and check the stated percentage. If the casino shows 90.5 %, consider switching sites—some run the full-fat 96.8 % build.
Cartoon Visuals, Ambient Ocean Sounds, and Bob’s Quips
Graphics lean into bright cartoons. Bob stands starboard, pulling a lever with each spin while gulls chirp softly overhead. Reviewers note that the orchestral soundtrack is “more energetic than usual,” providing momentum without drowning out reel clicks. Occasional one-liners “Another keeper!” give character without looping too fast, keeping vibes relaxed.
