SLOT SESSION // 1,500 SPINS
At Genii's declared 96.11%, a run of 1,500 spins at this bet averages out around -58× stake, shown as the dashed line. This one ended at 16.1×, close to where the average run lands. One session swings hard either way; the gap is the swing, not the game's payout rate.
The driest stretch ran 15 spins without a single win, spins 328 to 342.
All 10 share one vertical scale, so their shapes are comparable. The deepest block lost -83.4× the stake, while 5 finished in profit, the best at +142.5×. These are consecutive blocks of one continuous session, not 10 separate sittings: the balance never reset. Block 1 was played through the game's own interface; the rest replayed the bet call directly. Same numbers either way; only the first can be photographed.
7 frames captured by the rig during the recorded session. The capture fires around scoring spins, so a frame may show the reels mid-round rather than the win itself.
Our review of Big Blue Fishing
This Big Blue Fishing review comes from a casual player, not a lab: I tested Genii's slot over 10 separate sessions in September 2026, about 150 spins each, 1,500 spins in total at a flat 5.00 stake. My verdict up front: it's worth playing if you like medium volatility with steady small wins, because wins landed on 31.7% of my spins; the run returned 101.1% against a stated RTP of 96.11%, with a best single win of 113x. Every spin ran in free play mode, so the stake was play money rather than real cash.
The figures below are all 10 sessions added together. Each session was a fresh launch of the game in its own browser with its own balance, and the balance reset between them.
The stated RTP was read from the game's own server during the run, not copied from a catalog. One honest caveat: 1,500 spins spread across 10 separate sessions is still one recorded sample, not a measurement of the game's payout rate, which only settles over tens of thousands of spins. Treat 101.1% as what this sample happened to give back.
The volatility here is medium, and that's exactly how it played. Wins landed on 31.7% of spins, roughly one in three, so the balance kept getting small top-ups instead of sitting silent for long stretches.
The medium tag cuts both ways, though. My longest run without any win at all was 15 spins, and the deepest hole I sat in was a 166x drawdown against the stake. Fifteen dead spins at a flat 5.00 is where you feel it: long enough to notice, never so long it felt endless.
The single moment of the test was one 113x hit, the only 100x+ win in all 1,500 spins. That one spin did most of the work in getting the run to +16x overall. Five sessions ended in profit and five didn't.
Pros:
Cons:
Big Blue Fishing suits casual players who enjoy a medium-volatility game with frequent small wins and who can sit through a drawdown as deep as 166x without stressing. At a flat 5.00 bet, that means playing only with a balance you're genuinely comfortable watching shrink during a rough patch. If the base game keeps you entertained on its own, this slot will treat you fine. If you need constant fireworks or a realistic shot at the 218x top prize, my run suggests looking elsewhere.
My score: 7/10. The game returned more than its stated RTP over my test and behaved exactly like a medium-volatility slot; it stops short of a higher mark because the run produced only one big win in 1,500 spins and five of the ten sessions finished below water.
So the bottom line matches the one up top: a solid, honest medium-volatility slot I'd happily spin again, with the reminder that my +16x finish was luck over one sample, not a property of the game.
18+. Slots are entertainment, not a way to make money: play only with what you can afford to lose, and treat every spin as paid fun.
The RTP is 96.11%, which is approximately average compared to the industry benchmark of around 96%.

Big Blue Fishing is a June 2022 release from Genii that pairs a fishing theme with underwater visuals. The slot keeps things straightforward on a 5x3 grid.
Wild symbols substitute for regular symbols to complete winning combinations, while Multipliers can boost payout values. Scatter symbols count wherever they land, and Free Spins open a bonus round played without further stakes.
The Hold And Win mechanic locks valuable symbols in place while the remaining positions respin, giving additional chances to fill the grid with prizes. Instant Prize symbols carry immediate cash values that pay out directly when landed.
The 96.11% RTP sits right around the 96% industry average, meaning the theoretical return is competitive without standing out. Medium volatility produces a balanced session profile—wins arrive with reasonable frequency and scale, avoiding the long dry spells of high-volatility games while also lacking the explosive single-spin potential. The 218x max win is modest, capping the upside at a level that casual players won't mind but serious hunters will find limiting.
As a Fishing and Underwater slot, Big Blue Fishing leans into aquatic tranquility. The expected atmosphere combines open-water serenity with the quiet tension of waiting for a catch.
Big Blue Fishing earns a 4/10 rating as a functional but unremarkable release. The feature set checks boxes without surprising, the medium volatility suits players who prefer steadier sessions, and the 218x ceiling removes any real jackpot appeal. It works for relaxed spinning, though those seeking memorable mechanics or substantial win potential will find little here. Try the free demo to see if the pace matches your preference.
