McKinsey Solve Game: 2026 Assessment Hub

The McKinsey Solve assessment (formerly the Problem Solving Game, originally built by Imbellus) is a gamified online test — typically 65 to 85 minutes depending on your invitation — that plays a major role in whether your McKinsey application advances to interviews. McKinsey states that Solve results are weighed together with the rest of your application, but in practice it acts as a key screening gate. In 2026 the assessment draws on three games: the Red Rock Study, Sea Wolf Game, and the Sustainable Futures Lab — though the exact mix varies by office, role, and recruiting cycle, and some candidates receive only two of the three. McKinsey doesn't publish pass rates, but most estimates put the failure rate around 70%, and you get just one attempt per application: failing typically means a 12–24 month wait before reapplying. If you prepped earlier, check what changed in the McKinsey Solve before you trust older material. This hub collects everything on the current format: complete game guides, timed simulations of all three games, and free diagnostic tools.
