4 Fantastic Fish Gigablox Slot Review — 4ThePlayer

4 Fantastic Fish Gigablox is a 6×6 GigaBlox video slot released by 4ThePlayer, a London-headquartered studio founded in 2018. The game runs on a reel set that can grow in size during play, generating up to 46,656 ways to win, and it has a medium-to-high volatility rating and a substantial payout ceiling. The Cash Collector respin feature offers a route to larger payouts, although its triggering frequency is not specified here.

Core Gameplay Experience

The 6×6 grid is the defining structural feature of 4 Fantastic Fish Gigablox: unlike a fixed-payline slot, its reel set can change shape mid-session, which is what pushes the ways-to-win count to 46,656 at full size. This reel-set-changing mechanic means the grid you see on a given spin is not guaranteed to be the one you see on the next, and the visual difference between a narrow base-game grid and a fully expanded one is the main rhythm driver of the session.

Visually, the slot is built around an underwater fishing theme: sharks, crabs, starfish and a fisherman’s boat sit against a dark blue ocean backdrop, with fish symbols carrying the bulk of the paytable. Players who enjoy the broader catalogue of Pirates & Sea themed slots will recognise the setting, though the mechanics here lean closer to a collector-style bonus round than a pirate adventure narrative.

Features and Mechanics

The respin round — described by the provider as a Hold and Win mechanic — is paired with a Cash Collector element: certain symbols function as a collector that gathers value from other positions during the respin sequence before the round ends. A Mega symbol (4×4) can land across the grid and occupy multiple positions at once, effectively compressing several matching symbols into one bigger block, which is one of several ways the game inflates match sizes rather than relying purely on ways-to-win count.

Symbol exchange and stacked symbols work alongside a random multiplier that can apply during respins, and the bonus game itself is reachable either organically or through a buy-bonus option that lets a player pay to enter the feature round directly. A jackpot element sits on top of this structure, and the catalogue also lists the slot under slots with Big symbols, reflecting how often oversized blocks appear once the reel set expands.

RTP, Volatility and Payout Model

4 Fantastic Fish Gigablox carries a listed return to player of 94% on a medium-to-high volatility profile, with outcomes that can vary considerably across sessions and larger individual hits possible when the Cash Collector round lands well. The provider’s own listing for the title shows configured RTP versions spanning roughly 94% to 96%, including a Germany-specific setting, so the exact theoretical return a player sees depends on which version an operator has deployed — a detail covered by the game’s RTP-range feature rather than a single fixed number.

An RTP of 94% sits in the 5th percentile of the 4,481 slots in our catalog with a published RTP, against a catalog median of 96%, which places this title toward the lower end of return rates for games of this type. The 12,000x maximum win exceeds the 2,500x catalog median reported for slots with a published payout ceiling. Its updated percentile position has not been recalculated, so the previous 77% comparison is omitted.

At a 0.10 minimum stake, 100 spins cost 10.00 in stake currency before any wins; at the 80.00 maximum stake, the same 100 spins cost 8,000.00. Players sizing a session around this slot’s medium-to-high volatility profile should choose stakes and loss limits that allow for uneven results; the frequency of Cash Collector triggers is not guaranteed.

Similar 4ThePlayer Slots — Comparison

Across this group, RTP climbs from 94% up to 97% while ways to win range from 1,024 to 46,656, so a higher way count does not translate into a higher return here — 4 Fantastic Fish Gigablox and 4 Fantastic Lobsters share the lowest RTP of the group at 94% despite the former having by far the widest way count. The listed medium-to-high volatility of 4 Fantastic Fish Gigablox differs from the High ratings of the other games shown, so a ranking limited to high-volatility slots is not directly comparable.

Similar Multiway Slots from Other Studios

Of these four titles, 10 Lucky Spins carries the highest RTP at 97.2%, while 2 Million B.C. sits lowest at 91.94%. Published maximum wins range from 1,000x for 10 Lucky Spins to 5,000x for 15 Dragon Pearls, with 2 Million B.C. reported at 4,496x. At 12,000x, 4 Fantastic Fish Gigablox has the higher stated maximum win, with a Medium/High volatility rating.

Conclusion

“A reel-expanding Cash Collector slot with a 12,000x ceiling, multiple RTP settings and medium-to-high volatility.”

At the listed 94% RTP and Medium/High volatility, 4 Fantastic Fish Gigablox offers a 12,000x maximum win and a 46,656-way grid.
