How to Get the Rich! Millionaire Achievement in How to Fish
Updated 2026-08-26
Money guide for the 'Rich! Millionaire' achievement in How to Fish: it tracks a single item's sale value, not your wallet. The verified value levers — expensive creatures, cooking premium, killscore bonuses — and how to stack them.
What the achievement actually tracks
'Rich! Millionaire' (8.3% global unlock rate) reads "Sell something worth 100,000 or more." Community testing confirms this means a single item's displayed sale value — not your wallet balance, and not a lifetime total. Selling fifty items worth 2,000 each does nothing; one item reading six figures at the vendor does.
The three value levers you can verify
Every public source points at the same three levers, and the route is stacking them: 1. BASE VALUE — start from the most expensive thing you can sell. Third-party guides record the Goblin Shark at a $6,200 base price, the best ordinary sale in the game; late-game drip variants also sell at a premium over their normal versions. 2. COOKING — the grill raises an item's sale value before you sell it. Field guides describe cooking pushing a big creature's value toward 1.5x, which is why the Goblin Shark advice is always "run it across the grill first." 3. KILLSCORE — the multiplier system behind the 'Impressive' achievement (74% unlock rate) rewards stylish kills with bonuses, so the way you kill a high-value target matters, not just what you kill.
A practical route
Unlock the grill early (carry the Blue Shark to the Grillmaster on the Desert island — do not sell it). Build your bankroll with cooked Desert catches on the $15 Standard Lure. When you are ready, buy the Scientific Boss Lure ($5,800) on the Volcano, kill the Goblin Shark with the best killscore setup you can manage, cook the body, and check the displayed value before confirming the sale. If the number falls short of six figures, sell anyway and treat it as bankroll — the levers are documented, but no public source documents the exact full stack to 100,000, so expect a few attempts of pushing base value, cooking, and multiplier higher each time.
What about the casino?
The slot machine and roulette are real ('GOLD GOLD GOLD' at 61.6% and 'All in' at 24.2% confirm both), and a lucky pull can spike a big win. But both are RNG — there is no documented reliable route from the casino to a six-figure sale. Treat gambling as entertainment funded by spare cash, not as the plan.
The habit that matters more than the route
Read the displayed sale value before you confirm. The achievement fires on the number shown at the moment of sale, so the check costs you nothing and saves you from selling a 95,000 item you could have pushed further with one more lever. And flip the usual beginner instinct: cooked sells for MORE than raw, so never sell a big creature raw out of impatience.
How to apply this guide safely
Begin with “What the achievement actually tracks” and compare it with the objective, inventory, and controls shown by your installed build. Do not change several variables at once. If the guide concerns progression, complete one dialogue or hand-in and confirm the objective changed before sailing away. If it concerns combat, test the control or equipment choice on an ordinary encounter before spending a boss trigger. If it concerns troubleshooting, preserve the save and start with reversible checks such as restarting the session and verifying files.
Keep a short run record with the game version, solo or co-op state, host identity, starting objective, relevant equipment, steps taken, and outcome. Physics, network state, and retail patches can make two attempts look different even when both players describe them honestly. A controlled record lets you identify which condition changed. It also gives the developer a useful reproduction if the result points to a defect rather than a missed quest step.
Evidence and version check
This article uses GAMES.GG — How to Fish guides (Goblin Shark base price, cooking premium), Steam Community Achievements — How to Fish. Official store text and developer announcements establish supported features and broad progression. Steam achievement wording establishes that a named action exists, but it does not prove an exact coordinate, probability, price, damage value, or hidden timer. Community discussions can reveal a repeated problem and possible workaround, but one reply is not treated as a universal mechanic. Where evidence stops, the guide uses cautious testing steps instead of inventing a precise answer.
Before relying on an older route, check the Steam news and discussion dates against the updated date at the top of this page. Prefer the current in-game objective when it conflicts with a video or forum post. Avoid unknown executables, replacement saves, cheats, or destructive file edits offered as shortcuts. A legitimate workaround should be explainable, reversible, and testable without surrendering account credentials or deleting the only known-good save.
Completion check
Finish with “The habit that matters more than the route,” then verify the result in the system that matters: quest log for progression, inventory for items, Steam for achievements, or a repeatable symptom check for a technical fix. Do not treat a visual animation alone as proof that the save registered the event. Wait for a normal transition and inspect the state before selling items, changing hosts, or starting another objective. If the result differs from this page, send the URL, build number, exact steps, and observed result through the contact page; that evidence is how we correct guides without turning uncertain reports into false facts.
