How to Fish — Gambling Guide
Roulette, slots, green bets, and how not to bankrupt the island run.
How to Fish lets you wager fish money at island casinos. There is no real-money gambling. You are betting coins you earned by catching, shooting, grilling, and selling. Dazed Games added the casino during development because the fantasy is a drunken boat crash that never quite gets responsible — and the Steam listing is explicit that you gamble fish, not cash.
Used well, a short roulette session funds the next rod or a crate of dynamite. Used poorly, you walk back to the shore with a starter stick while your friends already unlocked the next island. This guide covers the tables, the All in achievement, and a bankroll rule that keeps co-op groups from arguing.
What You Are Actually Betting
Coins come from selling fish, seagull kills, quest turn-ins, and trick shot bonuses. The casino does not print a separate currency. If you empty the wallet, shops still charge the same prices. There is no pity payout.
Treat gambling as an optional multiplier on money you can afford to lose. The Money-Making Guide is the reliable engine. The casino is a spike — up or down.
Roulette
Roulette is the table most Steam achievements care about. You place a bet, the wheel spins, and the payout depends on the color or number you picked.
- Outside colors (red / black): More frequent hits, smaller multiplier. Fine for warming up a bankroll you already padded with sales.
- Green: Rare, huge multiplier. This is the All in requirement: take part in roulette, bet on green, and hope it lands. You can complete the achievement on a small stake. You do not need to dump the entire island treasury.
- Straight numbers: Highest risk. Skip these until you are doing a meme run, not a progression night.
A practical pattern: sell a stack of common fish, take ten to twenty percent of that stack to the wheel, and stop after two losses in a row. If green hits once, cash out and buy the rod you came for. The table will still be there after the next boss.
Slots
Slots are noisier and less readable than roulette. They exist for chaotic co-op clips, not for planning a Bean speedrun. If you cannot see the pay table clearly, assume the house edge is worse than color bets and keep stakes tiny.
Do not slot the money earmarked for:
- The next rod upgrade (always first in the Gear Hub priority list)
- Explosives for the coming boss
- Boat engine if you are chasing I am speed
Bankroll Rules That Survive Co-op
Shared sessions create the real danger. One player treating the casino as entertainment while three others need a shotgun for Island 2 is how lobbies implode.
- Buy the upgrade first. If the shop has the rod or gun the group agreed on, purchase it before anyone walks to the wheel.
- Cap the night. Agree on a coin ceiling — for example five percent of the party wallet — and stop when it is gone.
- Split wallets mentally. Even if the game tracks money per player, talk as if you have a raid bank. Announce bets in voice chat.
- Never chase. A green miss is not a signal to double. It is a signal to fish for ten minutes.
- Host last. The host should not be the one spinning while the lobby is trying to board a boat. Physics plus a distracted driver sinks more runs than a bad wheel.
PixelNitro’s launch-week co-op writeup says the same thing in fewer words: do not gamble money the team cannot afford to lose. That advice aged well after the August 20, 2026 launch spike.
When Gambling Is Correct
There are windows where a bet is rational.
- You already bought the island’s key upgrades and have surplus commons rotting in inventory value.
- You need one burst of coins for a shop rotation item (explosives, special ammo) that will disappear, and a color bet is cheaper than another twenty minutes of grinding.
- You are on a dedicated achievement pass for All in and you brought a throwaway stake.
- You are playing a community challenge such as “casino only after bosses” and everyone opted in.
There are windows where it is never correct.
- First hour on Island 1. Sell, buy a rod, learn tension. Casino comes later.
- Immediately before a boss you have not beaten. Gear beats luck.
- After a Steam hotfix if you already crashed once that night. Stop adding variance.
Casino and the Rest of the Loop
Trick shots still beat the wheel for consistent coins once you can land 2x and 3x bounces. Seagull farming is more reliable than slots. Boss loot is the big spike that should go into shops, not green.
If you want the full economy picture, read Money-Making then come back here for the optional spike. If a friend is tilting at the table, send them to Seagulls for a combat palette cleanser.
