Your Solve invitation gives you a short window and one real run. Every game you rehearse before it is a clock and interface you don't have to figure out while your score counts.

10 Redrock Study scenarios: Data collection, calculation and a written report on a 35-minute clock, so the Research Journal and Cases phases feel familiar before your real timer starts. 10 Sustainable Futures Lab scenarios: Decision-modeling tasks with trade-offs on a 20-minute clock, so you rehearse the multi-turn Lab controls before an 85-minute invitation. Unlimited Sea Wolf runs: The systems-thinking task; every run generated from a shareable code and checked before you play: skip the preference stage and each site has a 100% answer, so every rerun is fresh practice. Archive: 2 Ecosystem Creation games: Candidates and prep sites report McKinsey phased this game out of most Solve invitations during 2025. Kept as an archive, so you can practice it if your invitation names it. A report after every run: The results screen and a feedback PDF, so you see where the minutes went before your next run. B1 · The Solve Playbook: A by-hand method for each game on pen and paper, so you walk in with a repeatable scratchpad workflow. B2 · Sprint to your test date: A day-by-day schedule for the last 14 days before your test, so you know what to run each evening.
