SolveForge rebuilds the three games McKinsey is actually using right now: Red Rock, Sea Wolf, and the Sustainable Futures Lab. Same phases, same clock, same steps that lock behind you. You get a score the second you finish. The retired Ecosystem game is still here too, if you want the extra reps.
Solve is the current name for what older guides call the McKinsey Problem Solving Game, the Imbellus test or the McKinsey Digital Assessment. Same test, one name change at a time.
Free to start, no card needed. A McKinsey pass is a one-time $29 for 30 days or $69 lifetime, never a subscription.
Each simulator runs the same phases and time limits as the real thing, and scores you by the same rules.
Investigation with the Research Journal, then Analysis on the calculator, then the Report. Leave a phase and it locks. Six cases at the end.
Three contaminated sites, four steps each. Build a profile, sort the microbes, assemble a prospect pool, then pick exactly three for the treatment.
Twelve branching decisions, four options each, and five stakeholders who remember what you did. There's no right answer. You're scored on whether your choices hang together.
Dropped from Solve in 2025. Build a food chain that survives in one habitat. Kept here because it's still a good reasoning drill.
Honest, in-depth breakdowns of every game: what it measures, how it's scored, and where people lose points. No signup, no paywall.
Format, timing, what each game measures, and an FAQ. Start here if you just got your invitation.
Read the guide βThe three one-way phases, a timing split, the math it tests, and worked examples of the traps.
Read βThe four steps, the exact efficiency formula, and a worked microbe-selection example.
Read βThe newest game: 12 branching decisions, five stakeholders, and how consistency is scored.
Read βTheir online screens are different tests, not versions of Solve. Same approach here: honest guides, and practice written from what's publicly known about each format.
SOVA or TestGorilla: numerical, logical, verbal and situational judgement. Guides for both platforms, plus timed practice sections.
Bain overview βThe Casey chatbot case, SHL's CCA, or a reasoning test, depending on the office. What BCG's own pages say, office by office. Practice coming soon.
BCG overview βFormat, length, what each tests and what overlaps, for anyone who applied to more than one firm.

Every run is scored out of 100 and saved. Your SolveScore is your best result in each game added together, so 400 is a perfect sweep. Boards run for this week, this month, and all time.
There are 22 trophies across McKinsey and Bain. The first one lands on your first run. The last few are hard to get.
Post a score βNothing to install. The idea is to run the games often enough that the mechanics stop costing you time.
Start with Red Rock or Sea Wolf. Those are the two you'll meet first.
Real phases, real time limits, and steps that lock behind you once you move on.
Your score comes up straight away. Where the game has a mathematically optimal answer, you get that too.
Every run counts toward the weekly, monthly and all-time boards.
Solve marks your process, not just your answers. If you already know the rules, you spend your time solving instead of working out what the game wants, and you finish with room to spare. None of it is hard once you know what's being optimized. The problem is that the first time you meet these games, on a live timer, is a terrible moment to work that out.
That's the whole idea here: your first real attempt shouldn't be your first attempt.
