Bob Marlin Goes Deep Slot Information

I've had my fair share of sea slots, and Bob Marlin Goes Deep sticks to a 5-reel setup that shifts from 5x4 to 5x7 with 1,024 up to 16,807 ways. Stakes run from 0.10 to 125 per spin. The default RTP sits at 96.8%, though there's a 90.5% variant out there. Volatility is low, base hit rate about 20.67%, and the cap is 3,905x. The vibe is relaxed, but the core loop leans on reel growth, free spins, and collection progress.

Paytable wise, lows are J, Q, K and A paying 0.6x for five. Highs are fishing bits like a can of worms, a lure, a reel, and a tackle box, worth about 0.8x to 1.4x for five. The big hitters are Super High Paying fish on golden tiles, active only in Collection Free Spins, paying 2.8x to 4x for five and scoring from two of a kind. There's no wild. Bonus symbols show as a boat, while collectable fish land only on expanded rows.

Bob Marlin Goes Deep: Slot Features

Features centre on expanding rows, two flavours of free spins, and a colour-coded collection. Bonus symbols can extend the grid by up to three extra rows, pushing the layout to 5x7 and opening 16,807 ways. Height resets between base spins, so momentum comes from hitting repeat boosters in one go. The main free spins need three bonus symbols, while the collection path builds through fish that only appear on the added rows, leading to a short but sharper stint with top symbols.

When three boats land together, 10 free spins kick off on a fully expanded 5x7 matrix. No extra boats drop during the round, and the collectable fish sit it out as well. You simply get the larger layout for the whole feature, which can throw out the odd multi-way. In my sessions it felt steady rather than thrilling, a change of gear rather than a surge, as the paytable doesn't jump and the pace mirrors the base with a wider canvas.

Collections run on four meters for blue, green, purple, and orange fish. You start with three orange already banked. Collecting five of one kind triggers five Collection Free Spins on the full grid, using the average stake placed while filling that meter. If more than one completes, they play in the order blue, green, purple, then orange. Only the matching Super High symbol joins the reels, pays from two of a kind, and hits the top line of 2.8x to 4x for five.

Expanding Reels in Bob Marlin Goes Deep

Bonus symbols tend to land on the left, middle, and right, and each one adds a row to the bottom, up to three extra in a single spin. The height then resets before the next base spin. In practice I often saw one-row bumps that came and went, with the odd climb to 5x7 helping multi-way lines. It's a neat nudge mechanic rather than a chain reaction, and it sets up the boats or fish you need without flooding the screen.

Free Spins in Bob Marlin Goes Deep

Three boats landing together light up 10 free spins on a 5x7 layout. No boats or collectables appear during the round, so there's no retrigger path and no meter work here. It's all about using the full height for extra ways, hoping the premium kit lines up. I found it serviceable as a pace change, with modest hits flowing through, but it rarely felt like a breakout moment because the paytable stays the same and the reels don't cascade.

Collectible Symbols in Bob Marlin Goes Deep

Collectable fish only show up on the extra rows added by boats during the base. That means progress is tied to hitting growth first, then hoping the right colours land. You begin with three orange fish pre-loaded, which trims the grind on that meter. Completing five of the same colour moves you to a short five-spin stint on the full grid. In my play, blue and green felt slower to fill, as one-row lifts don't always leave much room to catch them.

Collection Free Spins run with the average stake used while completing the meter. If more than one set finishes on the same spin, they fire in sequence blue, green, purple, then orange. Only the matching Super High symbol is active, pays from two of a kind, and tops the card at 2.8x to 4x for five. There are no boats or collectables in this mode, so it's a focused burst that lives or dies on whether those gold fish show up.
