SolvePrep is the only preparation tool that replicates the complete 2026 McKinsey Solve assessment. Each simulator mirrors the real format, timing, and scoring — so you experience the full test before test day.
You Only Get One Shot at the McKinsey Solve
The McKinsey Solve assessment is a one-time, high-stakes test with no official practice material. Most candidates go in completely blind — unfamiliar with the format, unsure of the scoring, and running out of time before they even understand the game.
Don't be one of them. McKinsey doesn't publish pass rates, but most estimates put the failure rate around 70%. A single practice session can be the difference between advancing to interviews and getting eliminated.

Practice the Full McKinsey Solve — All Three Games
Each simulator is built to match the real assessment's format, timing, and difficulty. Together, they cover 100% of the McKinsey Solve.
Sea Wolf Game — Microbe Selection
Clean 3 contaminated ocean sites by picking the right microbes for each. Filter the pool by attribute ranges, manage desirable and undesirable traits, and assemble a final 3-microbe selection per site under a tight timer. This is the game most candidates find hardest.
Red Rock Study — Geoscience Investigation
Investigate geological data across multiple case studies. Analyze research, highlight key values, answer quantitative questions, and write a scientific report — all under time pressure.
Sustainable Futures Lab — Situational Judgment
Navigate realistic team scenarios and rank competing priorities in McKinsey's newest Solve module. Each answer shapes the next question through adaptive branching, testing your decision-making consistency under time pressure.

What Is the McKinsey Solve in 2026?
The McKinsey Solve (formerly the Problem Solving Game) is a digital assessment McKinsey uses early in its recruitment process. It replaced the traditional PST and is designed to measure cognitive abilities including critical thinking, decision-making, and systems thinking.
The assessment consists of three main games: the Sea Wolf Game, where you pick microbes to clean three contaminated ocean sites by matching attribute ranges and managing desirable / undesirable traits; the Red Rock Study, a geoscience investigation task; and the Sustainable Futures Lab, a situational judgment test with adaptive team scenarios.
SolvePrep offers a near-identical simulation of the complete McKinsey Solve assessment, updated for 2026 — not just individual game replays, but the full preparation experience covering all three modules. Practice Sea Wolf, Red Rock, and the Sustainable Futures Lab in our McKinsey Solve simulators, learn how to prep for McKinsey Solve, or see what counts as free McKinsey Solve practice before you pay for anything.
