In Dazed Games’ Steam game How to Fish, get Rich! Millionaire by selling a roulette green payout item worth at least 100,000 after farming and lava-cooking a high-value island 5 fish.
Rich! Millionaire is one of the trickier post-game achievements in How to Fish, the physics fishing-and-shooting game from Dazed Games on Steam. You do not have to grind up to 100,000 one small sale at a time — the practical route runs through roulette on the fifth island, the volcano.
The roulette route to a 100,000 sale
The requirement is blunt: sell something worth 100,000 or more. Selling raw catches will never realistically get you there, but the island 5 roulette does the heavy lifting for you. Betting on green pays out 35x the value of the item you wager, and it pays that value as an item you can then sell — so a single well-chosen fish becomes a five-figure payout in one spin.
Key That is why this pairs so neatly with All in, which unlocks the moment you bet on green and win. Line the two up and one lucky spin can hand you both achievements at once, so it is worth going into this with green as your only bet.
Minimum fish value before you bet on green
| Target | Value |
|---|---|
| Sale value needed | 100,000+ |
| Green roulette payout | 35x the wager |
| Minimum wagered value | 2,858 |
| Raw fish before 1.5x cook | ~1,906 |
| Safer cooked target | ~3,200 |
The math sets a hard floor on what you can bet. Since green multiplies by 35, the wagered item has to be worth at least 2,858 (100,000 divided by 35) for the payout to clear the threshold. Lava cooking multiplies a fish’s value by exactly 1.5x, which means a raw fish worth roughly 1,906 becomes a legal bet after cooking. Cut it that fine, though, and a slightly imperfect catch can leave you paying out at 99,000 — so aim a little higher.
Treat 3,200 after cooking as your real target rather than the bare minimum. That cushion means an average roll of the multiplier still lands you comfortably past 100,000 instead of stranding you just short of the achievement.
Fish on island 5
Work the volcano island, where the catches are valuable enough to reach betting range.
Lava-cook every catch
Cooking multiplies value by 1.5x, so run your fish through the lava before you decide what to do with them.
Check the value with F
Press F to inspect each cooked fish and read its exact worth.
Keep threshold fish for green
Set aside anything at or above your ~3,200 target as ammunition for the roulette.
Sell the lower-value fish
Everything under the threshold gets sold normally to pay for more lures.
Repeat until green lands
Keep the loop running — new lures, more fish, more spins — until green finally hits.
Only bet fish above the threshold
The one mistake that wastes a good spin is betting a fish that is too cheap. A green win still fails Rich! Millionaire if the payout comes in under 100,000, so hitting green on a below-threshold fish burns your luck for nothing. Only ever put a fish worth your target or more onto green.
The upside is that you do not need volume. There is no bet cap, so a single sufficiently valuable fish is all it takes — whenever green lands on that one qualifying wager, the sale clears the achievement.
Inspect every cooked fish with F and only load fish worth about 3,200 or more onto green — that single habit stops a lucky spin from paying out below 100,000.
How long green takes
Green is one pocket in 37, so this comes down to RNG. It might land in a handful of spins or take dozens — there is no fixed timeline, and the honest expectation is that you keep the farming loop going and let the odds come to you.
