Where it sits in the assessment
The Sustainable Futures Lab is the third game, after Red Rock Study and Sea Wolf, and it runs about 20 minutes. It only appears on the longer invitation: a 65-minute invite means Red Rock and Sea Wolf; an 85-minute invite adds Future Lab. Your invitation email states the duration, so you can tell in advance exactly which games you'll face.
Because it only launched in March 2026, be careful with older advice. Reddit threads and guides from before 2026 don't mention it at all — and some describe the retired Ecosystem game as if it were still on the test. It isn't; it was dropped in 2025.
The format: 13 prompts, one evolving story
You lead an environmental research team through a single continuous scenario:
- One priority-ranking prompt — a drag-and-drop ordering of objectives that sets your baseline.
- Twelve branching decisions — each presents a situation with four options. Your choice triggers a consequence and reshapes the situation you face next. Two candidates who diverge at decision three are living different stories by decision eight.
Five stakeholders — think funders, partners, your own team — react to what you do. Their relationships with you shift as the scenario unfolds, and later decisions land differently depending on the goodwill you've built or burned.
How it's scored: consistency, not correctness
There is no mathematically right answer, which is exactly why people flounder. What's being measured is whether your judgment hangs together across five dimensions: prioritization, deciding under uncertainty, reading messy information, balancing trade-offs, and handling stakeholders.
Flip-flopping is the failure mode. If you play the cautious consensus-builder for four decisions and then lurch into unilateral risk-taking because an option looked clever, the inconsistency is the signal — not either choice on its own.
How to prepare
- Pick a posture in the first two prompts, then hold it. Decide what kind of leader you're being — transparent, evidence-first, stakeholder-balancing, whatever feels natural — and let that filter every later choice. Your priority ranking in prompt one is a commitment; treat it as one.
- Read the consequence text. Each decision's outcome tells you how stakeholders moved. That's not flavor — it's the state of the board.
- Don't optimize for being liked. Keeping every stakeholder happy at all times isn't possible by design. Trade-offs are the point; consistent trade-offs are the score.
- Run it more than once. The mechanics — branching, stakeholder tracking, pacing across 12 decisions — stop costing you attention by the second or third run, which frees you to actually think. That's the entire case for practicing it at all.
FAQ
Is the Sustainable Futures Lab on every invitation?
No. 65-minute invites are Red Rock + Sea Wolf only; 85-minute invites add Future Lab. Your email states the duration.
Are there right answers?
No single decision is right or wrong. Consistency across decisions is what's measured.
Is it just a personality test?
It's closer to a judgment simulation. Because consistency is measurable, practice genuinely helps — you learn to pick a posture early and hold it under branching pressure.
Is this the real McKinsey game?
No. SolveForge is an independent practice tool rebuilt from publicly documented mechanics. Nobody can sell you the real games, and you should be suspicious of anyone claiming otherwise.
