Hi Rajesh,

Congrats on getting the Solve invitation!

When it comes to preparing for the McKinsey Solve assessment (also known as the Problem-Solving Game), the best approach is to focus on developing structured thinking, pattern recognition, and data interpretation. While McKinsey doesn’t release official practice material beyond the sample on their website, here are a few useful ways to prepare:
    1.    McKinsey’s Official Practice Game:
Make sure you complete the official sample game provided in the invite — it gives you a good feel for the mechanics, pacing, and interface.
    2.    Logical Reasoning & Cognitive Puzzles:
Practice with online logic games, pattern recognition puzzles, and numerical reasoning tests (similar to GMAT Integrated Reasoning or SHL-style assessments). These will sharpen the type of thinking Solve tests.
    3.    Ecosystem Simulation Prep:
Some of the Solve scenarios involve balancing ecosystems — try to familiarize yourself with basic resource management games and simulations that involve cause-and-effect decision-making.
    4.    Reddit & Prep Platforms:
Many candidates share their experiences and practice resources on forums like Reddit (e.g., r/consulting). 

Most importantly, approach the test calmly and focus on structured thinking rather than speed alone. Many candidates who prepare this way perform very well, even without formal “prep packs.”

Good luck with the assessment! Let me know if you’d like more help!

Best,

Evelina

Hi Rajesh,

Q: Are there any prep materials which I can practice before I take the assessment

Yes, you can find courses and also full simulations of the games to practice in advance.

The current version of Solve (2025) includes three games:

  1. Ecosystem Management (35 minutes) - You need to find 8 species to build a food chain and the right location for them to survive
  2. Redrock Study (35 minutes) - You need to collect relevant information and answer questions based on the information provided about a natural environment
  3. Sea Wolf (30 minutes) - You need to select 3 microbes to cleanse the ocean in 3 different sites

If you want to prepare, you can find a course covering all the games at the link below (full disclosure, I am the author):

For any questions about the game please feel free to PM me.

Good luck!

Francesco
