Quick answer

Rich! Millionaire unlocks when one item is sold for at least 100,000. Reach the Volcano stage, catch a replaceable high-value fish, cook it without burning it, and inspect its displayed value. Current retail field guides report that roulette green returns an item worth 35 times the wager. Bet only a cooked item showing at least 2,858, collect the green payout item, confirm that it displays 100,000 or more, and sell that item to a vendor.

Why 2,858 is the minimum displayed wager

The threshold is transparent arithmetic based on the community-documented 35x green payout: 100,000 ÷ 35 = 2,857.14. Because the wager must clear the target, the displayed cooked item should be at least 2,858. Do not cut it close if the game's displayed value rounds; a value around 3,200 gives a safer buffer. Inspect the actual item rather than relying on an old base-price table, because catch value and balance can change between patches.

Step-by-step Rich! Millionaire route

1. Reach the late-game Volcano route and keep inventory space for several replaceable catches. 2. Catch valuable normal fish with the Scientific Lure; do not wager a boss trophy or story hand-in. 3. Cook each candidate carefully, then inspect it and keep only items above your chosen green threshold. 4. Take one qualifying item to roulette and bet it on green. The item can be lost, so expect retries. 5. When green wins, collect the payout item instead of walking away. 6. Inspect the payout and sell it only when the displayed value is 100,000 or higher. 7. Confirm Rich! Millionaire in the Steam overlay or achievement list.

Failure branches

If you reached 100,000 in your wallet through many sales, that does not match Steam's one-sale wording. If green paid out below 100,000, the wagered item was too cheap; raise the displayed cooked value before the next attempt. If you won green but did not unlock Rich! Millionaire, collect and sell the payout item—the roulette win itself belongs to the separate All in achievement. If the fish burns or roulette loses, return to ordinary late-game fishing and use only replaceable catches for the next attempt.

Evidence and Patch 1.0.12 boundary

Steam officially states the 100,000 sale requirement. Two independent retail walkthroughs describe the cook → green roulette → sell sequence, and one publishes the 35x calculation. Dazed Games' public notes through Patch 1.0.12 do not document the roulette multiplier or cooking formula, so both remain field-guide evidence rather than developer-confirmed constants. That is why the safe completion check is always the current displayed value before you wager and before you sell.
