Free McKinsey Solve Practice Test
Play a complete game from our McKinsey Solve simulation for free. Work through a full Sustainable Futures Lab scenario from start to finish, get your performance report, and compare your decisions with Deniz's YouTube walkthrough of the same scenario.
Play the Free Demo
Sustainable Futures Lab opens with the Pelora Bay scenario, and you have 30 minutes, as in the real assessment. Redrock Island and Sea Wolf are locked in the demo. When you finish, enter your email address to see your report.
A Full Scenario, Not a Preview
A short preview shows you the interface, but not how you would perform.
That’s why the demo is a full scenario of Sustainable Futures Lab, the newest game in McKinsey Solve. McKinsey redesigned it in 2026 as a team leadership simulation, and it is the game candidates know least: many guides and videos online still describe the retired format.
In Pelora Bay, mangroves started declining after a severe storm season, and you lead a four-person research team to find out why. You play all three project days and make every decision yourself. At the end, you receive a full performance report with your results in four areas: Information Prioritization, Resource Allocation, Adaptive Problem Solving and People Judgment.
Compare Your Result with Deniz's
Deniz, Prepmatter's founder, recorded himself playing this exact scenario. Play the demo first. Then watch the video and compare: who he chose to speak to on Day 1, where he assigned each researcher and why, and how he handled each judgment call.
For the format and the strategy behind each stage, read our guide to the Sustainable Futures Lab.
What You Get in the Full Simulation
The demo is one scenario of one game. The full simulation is the most comprehensive McKinsey Solve practice we have built, and all three games were updated in November 2026:
- Redrock Island: 30 full-length scenarios.
- Sea Wolf: unlimited practice, with a different scenario every time you play.
- Sustainable Futures Lab: 30 scenarios, each with its own team, workstations and dilemmas.
The games are built from real candidate experiences to match the current format as closely as possible, and you get a performance report after every attempt.
The numbers behind it:
- 2,200+ candidates have prepared with the simulation.
- 97% of them passed the game.
- 880,000+ views on our Solve tutorials, the most-watched Solve preparation content globally.
Across all our courses, more than 17,500 candidates have enrolled, and our YouTube channel has reached over 2.6 million people.
You get 12 months of access for a one-time charge. If you don't place in the top 30%, we give you 50% of your money back.
