Sustainable Future Lab Simulator: How to Practice McKinsey's Newest Solve Game
McKinsey's third Solve game tests judgment, not math. A dedicated SFL simulator is now available. Here's how to use it to build consistent decisions—the skill the test measures.
Why a Sustainable Future Lab Simulator Matters
If you apply to McKinsey & Company in 2026 and your invite shows 85 minutes instead of 65, you will face three Solve games. One of them is the new Sustainable Future Lab (SFL).
This game is different. You won't use spreadsheets or calculations. You work through team scenarios. Each choice changes what happens next.
That creates a prep gap.
- For Red Rock Study, you can train data analysis and percentages.
- For Sea Wolf, you can train optimization logic.
- For SFL, reading tips is not enough.
You need to experience the decision flow.
That is the role of the SFL simulator.
What the SFL Simulator Covers
The simulator mirrors the structure, pace, and logic of the real SFL.
| Game Element | Real SFL | SolvePrep Simulator |
|---|---|---|
| Mission briefing with context | ✓ | ✓ |
| Priority ranking (4 actions) | ✓ | ✓ |
| Sequential team scenarios (~11 questions) | ✓ | ✓ |
| Adaptive flow (choices affect next steps) | ✓ | ✓ |
| Multiple-choice format (3 options) | ✓ | ✓ |
| ~20-minute time constraint | ✓ | ✓ (with timer) |
| Post-session behavioral feedback | ✗ | ✓ |
The key feature is the adaptive flow.
In SFL, each decision affects the next scenario. If you handle conflict in one way, the next situation changes. The simulator reproduces this branching logic. You see how your choices build on each other.
Unlike Red Rock or Sea Wolf, SFL has no single correct answer. It measures consistency in judgment across decisions.

The Four Skills the Simulator Builds
1. Structured Decision-Making Under Ambiguity
Each scenario gives you several reasonable options. None is clearly correct.
The simulator trains you to apply a consistent framework instead of guessing. After each session, you review whether your choices follow a clear logic.
2. Team Leadership and Collaboration
You will face:
- A disengaged teammate
- A dominant voice
- A split team
You decide how to act:
- Address behavior directly
- Create space for others
- Redirect the discussion
The test rewards effective team outcomes, not politeness.
3. Consistency Across Decisions
SFL tracks your choices across the full sequence.
Example:
- You push for consensus early
- Later, you shut down discussion in a similar case
This weakens your profile.
The simulator flags these contradictions so you can fix them.
4. Priority Setting and Sequencing
The game starts with ranking four actions.
This tests a core consulting skill:
- What is urgent
- What drives impact
- What depends on what
The simulator includes this task and shows how your order compares to structured consulting logic.
How to Use the Simulator
Step 1: Define Your Framework
Before you start, write down how you make decisions in teams.
Example:
- Direct vs indirect conflict handling
- Consensus vs speed
Keep it short. This is your anchor.
Step 2: Run One Full Session
Complete one session without overthinking.
Follow your framework. Move forward.
This shows your baseline behavior.
Step 3: Review Feedback
Check where your decisions match your framework—and where they don't.
Focus on contradictions. These matter most.
Step 4: Refine and Repeat
Adjust your approach. Run 2–4 more sessions.
Each run sharpens your judgment.
Target: 3–5 sessions total
Step 5: Add Time Pressure
Enable the 20-minute timer.
SFL requires careful reading. Missing details leads to weaker choices.
Time pressure shows whether your approach holds.
⚠️ Common Mistake
Do not try to guess what McKinsey wants. The adaptive design exposes inconsistent answers. A clear and consistent framework performs better than guessing.
Build Your Decision Framework
Run 3–5 sessions to develop the consistency the real SFL measures.

SFL Simulator vs Generic SJT Practice
You can use general situational judgment tests (SJT). They help with basic principles.
But they miss key SFL features:
| Dimension | Generic SJT Practice | SolvePrep SFL Simulator |
|---|---|---|
| Question format | Varies (often 4–5 options) | Matches SFL format (3 options) |
| Adaptive flow | Static — each question independent | Adaptive — answers shape next scenarios |
| Context | Generic workplace scenarios | Research team context matching SFL themes |
| Consistency tracking | Not measured | Tracked across all 13 questions |
| Consulting competency alignment | General leadership principles | McKinsey-specific competencies |
| Time-pressured practice | Rarely timed | 20-minute timer matching real assessment |
Best approach:
- Learn SJT principles
- Apply them in the SFL simulator
How SFL Fits Into Full Solve Prep
If your test is 85 minutes, you will complete three games across the McKinsey Solve simulation suite:
Red Rock Study (35 min)
- Focus: data analysis, percentages, case logic
- Priority: highest practice time
Sea Wolf (30 min)
- Focus: optimization, pattern recognition
- Learnable mechanics
Sustainable Future Lab (20 min)
- Focus: behavioral judgment
- Train via 3–5 simulator sessions
Prep Strategy
- Start with Red Rock and Sea Wolf
- Add SFL in the final 3–5 days
This avoids constant switching between skill types.
Who Should Use the Simulator?
Use it if your invite shows 85 minutes.
SFL appears often in:
- Germany
- Middle East
- Selected regions
If your invite shows 65 minutes, SFL may not apply yet. Still, one session helps you understand the format.

Frequently Asked Questions
Final Takeaway
SFL tests one thing: consistent judgment under pressure.
You don't prepare it by memorizing answers. You prepare it by applying a clear framework across many decisions.
The simulator gives you that environment.
Use it to build consistency before test day.
