Bob Marlin Goes Deep Slot RTP, Details & Wager Limits
Each base game spin in the Bob Marlin Goes Deep slot starts on a 5-reel, 4-row machine that offers 1,024 ways to win. Create winners by landing matching symbols on three or more adjoining reels (just two for the super high-paying symbols), starting from reel 1.
The minimum bet here is just 10p per spin. That’s low compared to many online slots. This rises to a maximum of £125 per spin. If you’re playing at UK online casinos, the max bet is capped at £5 per spin.
Head to the settings to adjust spin speed. It goes from very slow to super turbo. There’s also autoplay mode, where you can set between 10 and 1,000 spins with adjustable win and loss stop limits. Autoplay and turbo spin modes aren’t available to United Kingdom players.
You wouldn’t describe the Bob Marlin Goes Deep max win of 3,905x as a whopper of a payout. That figure is low compared to many new slots. Check the top progressive jackpot slots for the biggest potential payouts. What isn’t low is the Bob Marlin Goes Deep RTP of 96.8%. It’s a way behind the best RTP slots, but still a better-than-average number. The hit rate is 20.67%. On average, you’ll land a winner once every 5 spins.
These waters might be deep, but they’re not very choppy when it comes to variance. The volatility is low. Combine that with the small minimum bet, and it’s a good choice for players trying to eke out plenty of play with a small bankroll.
I netted my biggest haul of coins playing the Bob Marlin Goes Deep demo slot in the Collection Free Spins. You can try thousands of free slots here at online-slot.co.uk.
Bob Marlin Goes Deep Theme—Cast Off With a Cheeky Fisherman
The visuals in the Bob Marlin Goes Deep slot game are pretty basic. Bob the fisherman, wearing his wellies and oilskins, is a jolly fellow who pulls a lever to start each spin.
The reels contain low-value A to J playing card ranks, high-value fishing tackle symbols and super-high paying fish symbols. The colourful, cartoonish imagery stands out nicely against the simple sea-blue backdrop.
The sweeping orchestral soundtrack is more energetic than you usually find in a fishing-themed slot. It’s impressive enough, but doesn’t really match the light-hearted tone set by Bob on each spin.
The design is simple, but the visuals are clear and crisp. It doesn’t have the flair of some Yggdrasil slots, but it does the job nicely.
Here’s what the paytable looks like:
| Symbol | Payouts/Info |
|---|---|
J
|
3, 4 or 5 = 0.2, 0.4 or 0.6x |
Q
|
3, 4 or 5 = 0.2, 0.4 or 0.6x |
K
|
3, 4 or 5 = 0.2, 0.4 or 0.6x |
A
|
3, 4 or 5 = 0.2, 0.4 or 0.6x |
Can of Worms
|
3, 4 or 5 = 0.4, 0.6 or 0.8x |
Hook
|
3, 4 or 5 = 0.4, 0.6 or 1x |
Reel
|
3, 4 or 5 = 0.4, 0.8 or 1.2x |
Tackle Box
|
3, 4 or 5 = 0.4, 0.8 or 1.4x |
Blue Fish
|
2, 3, 4 or 5 = 1, 1.4, 1.8 or 2.8x |
Green Fish
|
2, 3, 4 or 5 = 1, 1.6, 2 or 3.2x |
Purple Fish
|
2, 3, 4 or 5 = 1, 1.8, 2.2 or 3.6x |
Red Fish
|
2, 3, 4 or 5 = 1, 2, 2.4 or 4x |
Bonus
|
3 = 10 free spins |
Bob Marlin Goes Deep Mobile Slot
The crisp design in the desktop version is on display if you’re playing at Bob Marlin Goes Deep casinos. The expanding reels make portrait mode a better bet if you’re playing on your tablet or smartphone. I found the experience very smooth when playing the game at mobile casinos. You won’t lose anything when compared to playing on a computer.
Bob Marlin Goes Deep Bonus Features
The design is simple, and it’s the same story with the Bob Marlin Goes Deep bonus features. Highlights include expanding reels, free spins and collecting free spins.
Expanding Reels
Each time a Bonus symbol appears on reels 1, 3 or 5, one extra row is added to the game engine. This also increases the number of ways to win. Reels can expand up to 3 times. When that happens, you’ll have 16,807 ways to form a winning combination. The reels reset to their standard size at the start of each new base game spin.
Free Spins
Land 3 Bonus symbols on the same spin and you’ll receive 10 free spins on the fully expanded 5-reel, 7-row, 16,807-ways-to-win machine.
Collectible Fish
Collectible Fish symbols can appear on the bottom row of the fully expanded reels in the base game. Each fish that lands is collected in its associated meter. Fill a meter with 5 of the same fish and you’ll activate the Collection Free Spins.
Collection Free Spins
Once triggered, you’ll receive 5 free spins on the fully expanded reels. A set of super-high-paying symbols is added to each reel. The exact symbol depends on the colour of the Collectible Fish that triggered the feature.
Bob Marlin Goes Deep Verdict: This Fishing Expedition Was A Little Too Sedate
There’s plenty of competition when it comes to fishing-themed slots. While Bob Marlin Goes Deep has ignored the cliched hook and win feature, it hasn’t replaced it with anything too exciting.
The expanded reels and free spins are fine as they go. The gameplay is all just a bit pedestrian.
On the plus side, the better-than-average return-to-player rate catches the eye. The max win of less than 4,000x is more tiddler than Great White Shark, though.
Bob Marlin Goes Deep is far from the worst slot I’ve played. It lacks a bit of excitement, though.
Keep going with the series and try Yggdrasil Gaming’s Bob Marlin Goes Splashing Wild Fight™ Rushing Wilds™. If you like casting off in the hope of netting a bumper haul of coins, check out the volatile Big Bass Bonanza 1000 from Pragmatic Play. Look out for free spins, multipliers and a 20,000x max win.
There’s also Fishin’ Frenzy Megaways from Blueprint Gaming, which has a whale-sized maximum win of 50,000x.
