How to Fish Gambling: Lucky Bait Casino Guide

How to Fish’s gambling happens at the Lucky Bait Casino on Island 4: you place a fish on the roulette table and bet on red, black, or green, and if the ball lands on your color, your fish’s selling value goes up. Red and black pay out a 2x multiplier, green pays 35x but has only one slot on the wheel, and if you lose the bet, you lose the fish entirely. This guide covers how to unlock the casino, how a bet actually works, the real odds, and how to win the All In achievement.

Where to Find the Casino

The Lucky Bait Casino is on Island 4, and you can’t reach it until you defeat the Pufferfish boss on the island before it. Beating the Pufferfish and turning in its drop to the Tourist NPC gives you the coordinates to Island 4 — sail there by boat and the casino is waiting once you arrive. See our Rocks Island walkthrough for the rest of that stop.

Before you start betting, stock up on an ample haul of low-quality fish. Since the outcome is essentially a coin flip on the color you choose, bringing expensive or rare catches to bet with is not recommended.

How to Place a Bet

Once you’re at the casino, head to the table in the center of the room. One side of the table holds the roulette wheel, while the other has a glowing yellow square where you place the fish (or fish) you want to bet.

After placing your item, bet on a color — red, black, or green — on the left side of the table. The wheel then drops the ball and spins; if it lands on your color, your item’s selling value increases by that color’s multiplier, and you can choose to bet again to keep stacking value. If it lands on a different color, you lose the item on the table for good.

Odds and Payouts

Red and black both carry a 2x value multiplier and, according to one source, roughly a 50/50 chance of hitting since they each cover more space on the wheel. Green is the high-risk, high-reward option at a 35x multiplier, but the wheel has only one green slot, which makes landing on it extremely rare and entirely down to luck.

There’s no pity system for the roulette table — the game doesn’t nudge the odds in your favor after a losing streak, so repeated attempts are just repeated luck, not a bill you’re paying down.

Smart Gambling Tips

It’s worth grinding out your weapon and gear upgrades before relying on the casino for extra income, since trick shots and regular fishing are more consistent money-makers than roulette. When you do gamble, bet with low-value leftover catches — fish with little to no multiplier — rather than your big, valuable ones, since a loss on the roulette table is permanent.

Unless you’re specifically chasing the All In achievement, red or black are the safer bets: their better odds make them the recommended choice over chasing the rare green multiplier for casual play.

The All In Achievement

Winning a bet on green — the 35x slot — earns you the All In achievement. Unlike most achievements in the game, this one can’t be worked toward through skill or grinding; it comes down entirely to landing that one rare slot on the wheel.

Since there’s no pity payout, the only real strategy is to keep placing low-value fish on green and spinning until luck lands in your favor.

Reel of Fortune vs. Roulette

The roulette table isn’t the only gambling-adjacent system in How to Fish — the Lucky Bait Casino name comes from the venue, but a separate feature, the Reel of Fortune, is where you can spend “drip creatures” or boss drops to get cosmetic skins for your gear. It rewards you with skins rather than currency, so it serves a different purpose from the roulette table’s value-multiplying bets — treat it as a separate system for cosmetics, not a way to make money.

Where Island 4 Fits in Your Playthrough

The Lucky Bait Casino sits on the same island as one of the game’s main boss fights, so you’ll likely pass through it while progressing the story rather than needing a separate trip. The island’s actual required boss — the Albatross — is covered separately in our boss guide, since defeating it, not the casino, is what unlocks the next island’s coordinates.

Is Gambling Worth It?

Both sources describing the casino agree on one point: gambling isn’t a reliable way to build wealth in How to Fish. Regular fishing, trick shots, and completing quests are described as more consistent income than the roulette table, and the recommended approach is to treat the casino as a side activity for spare low-value catches rather than a strategy.

If your goal is simply to see the roulette table in action or chase the All In achievement, a few spins with leftover fish costs you little. If your goal is building up cash for gear, the material collected here points toward fishing and combat instead.
