Overview
The optimum food chain, derived for you.
The Ecosystem Solver implements McKinsey Solve’s Ecosystem logic. It scores every starting location, selects the producer set with the highest calorie sum, and derives a maximum-length valid food chain — exactly as the game rewards.
Built on the same algorithms as the real assessment, it removes the manual trial-and-error so you can focus on understanding why the optimum chain works.
- ✓Producer scanFinds the highest-calorie producer set across the grid.
- ✓Optimum food chainDerives an up-to-8-species valid chain.
- ✓Reproducible logicThe exact scoring rules from the game — no guesswork.
- ✓Solves in your browserThe solving logic runs in your browser; results are saved to your account.

FAQ
Questions, answered.
How close is the Ecosystem Solver to the real thing?
It rebuilds the real Solve ecosystem game: the same species cards, food-web linking and three-site final selection, with McKinsey-style scoring. It's an independent recreation — the same shape and pressure, never the official content.
How do the runs work?
Your purchase lives on your account: three runs of Ecosystem Solver, unlocked the moment payment completes. Open the tool, confirm the entry prompt, and one run is consumed — re-run freely within that open session. Buy Ecosystem Solver or fold it into the McKinsey bundle.
Do my runs expire?
No. Runs stay on your account until you use them — buy now, practise when your assessment is scheduled. Only entering the tool consumes a run; within an open session you can re-run as often as you like.
Is there a refund guarantee?
Yes — for the McKinsey bundle: use every tool in it, and if McKinsey rejects you with a score below the 8th decile, you get a full refund within 30 days of purchase. This tool on its own is a single-product purchase, outside the guarantee: read the terms.
