How 4 Fantastic Fish plays
The setting is a fishing trip, and the regular symbols reflect it: fishing tackle and reels, a crab, a seagull and, at the top of the paytable, the fisherman. Wins are counted as ways across the 6 reels rather than along fixed paylines. The fishing boat is the wild, and the marlin is the scatter that opens the Respin bonus. What makes the base game unusual is that the fish themselves are worth money on any spin, and two extras, the Giant Squid and the jackpot fish on the last reel, add to what a spin can bring.
4 Fantastic Fish: 6 reels, 4 rows; fish symbols pay as ways wins. Cash symbols lock in place while the respins reset.
Cash Ways: fish that pay with the reels
4ThePlayer calls its mechanic Cash Ways. Fish symbols can land on every reel, and each carries a cash prize, with the prizes growing larger the further right the reel is. A fish prize is paid when the fish forms part of a winning ways combination, so there is no separate collector symbol to wait for. Reel six, the last of them, is also where the Big Game Jackpot Fish land.
The Respin bonus and its three lives
Between three and six marlin scatters start the Respin bonus. The reels that held a scatter stay in play and the others close, and any fish already showing on the triggering spin lock in place, their values paid when the round ends. You start with three lives. Each spin without a fish costs one, and every fish that lands resets the count to three, so the bonus only ends after three spins in a row with no fish.
The Shark and the Giant Squid
Two creatures change the Respin bonus. When an open reel fills with locked fish, the shark eats them, adds their cash prizes together and doubles the total, which also frees the reel for more fish. Whatever the four fish on that reel are worth together, the shark pays twice that sum. The Giant Squid can appear on any spin, in the base game too, rearranging fish so that they create a win or improve one that has already landed.
4 Fantastic Fish compared with Big Bass Bonanza
Both games turn fish into cash prizes, but they pay them in opposite ways. In Big Bass Bonanza, the money symbols are collected by wilds during the free spins, and every fourth wild retriggers the round with a higher multiplier. 4 Fantastic Fish pays its fish on any spin as part of a ways win on a larger 6x4 grid, and saves its multiplier for the shark, which doubles a full reel of fish in the Respin bonus.
| Game | Grid and lines | How fish prizes are paid |
|---|---|---|
| 4 Fantastic Fish | 6 reels, 4 rows, ways wins | On any spin, as part of a ways win; the shark doubles full reels in the Respin bonus |
| Big Bass Bonanza | 5 reels, 3 rows, 10 paylines | Collected by wilds in the free spins |

Frequently asked questions
How do the Big Game Jackpot Fish work in 4 Fantastic Fish?
They are special fish that land on reel six, the last reel, and each one points to one of four fixed jackpots: Big, Super, Mega or Ultra. Yggdrasil describes them as fixed rather than progressive, so they do not grow from spin to spin or across players. The game’s information panel lists what each tier pays.
Is 4 Fantastic Fish the first game in the series?
Yes. The June 2022 original came first, and Yggdrasil and 4ThePlayer have since built a run of follow-ups on the same idea, including 4 Fantastic Fish GigaBlox, 4 Fantastic Fish in Egypt and 4 Fantastic Fish Amazon Adventure. The rules in this guide describe the original 6x4 game only, so check each follow-up’s own information panel for how it plays.
What happens to a reel after the shark clears it?
It opens up again. Once the shark has eaten a full reel of fish, added their prizes together and applied its 2x multiplier, that reel is free to take more fish for the rest of the Respin bonus. Any new fish landing there also resets the lives to three, so a cleared reel keeps the round going as well as giving the shark more to collect.
