A solution to McKinsey's recruitment puzzles — eliminate the guesswork.

The most realistic McKinsey Solve practice available. Our Sea Wolf simulation and Redrock simulation recreate the real timed assessments — same phases, same pressure, same scoring — and the Sustainable Futures Lab tests project management and crisis decision-making under time pressure. The Sea Wolf Solver walks you through microbe selection across three contamination sites. For BCG candidates, the BCG Quantitative Reasoning simulation recreates the 40-minute numeracy test. The Ecosystem Solver derives the optimum food chain. One fair price for three runs.

How it works

Simulations and solvers, one disciplined approach.

Each McKinsey Solve game rewards a structured, repeatable method. Our simulations mirror the real timed assessments and our solvers implement the exact selection logic you'd do by hand — instantly and reproducibly — so you arrive at the optimal answer every time.

1

Most realistic simulation available

A full timed, 3-site Sea Wolf assessment that mirrors the real McKinsey Solve experience — same phases, same pressure, same scoring. Nothing else comes closer to the genuine thing. Three difficulty levels — Easy, Medium and Hard — with over 100 unique scenarios, so an optimum selection of microbes is not always guaranteed, exactly as in the real assessment.

3 difficulties · 100+ scenarios
2

Scoring provided at the end

Work through profile, categorization, prospect building and final selection under the clock. When time's up, you get a full AI-powered score breakdown — microbe routing analysis, timing and pacing analytics, decision-making insights, and a per-site effectiveness breakdown — so you can see exactly how you'd have done and where to improve.

When I applied before my MBA I didn't get an invite to R1 or a callback, I think it was partially because I ended up running out of time. Keen not to lose the opportunity this year, I decided to try this and I'm quite glad I did. Thankfully I got the email inviting me to first round shortly after this, so THANK YOU!

The Sea Wolf solver saved me — I just didn't have enough time to prep for this as I was handling loads of applications at the same time. It would be worth the £10 on its own twenty times over but I ended up getting the bundle.

Honestly skeptical at first, I thought it would be some vague framework but it's not. Strangely and I don't know how you guys did it the questions were very, very similar from the simulations. The solver was quite easy to use and took me about 4 minutes to punch in the numbers and get the answers.

Bought the bundle the night before my assessment and ran through two of each of the simulations. Didn't expect much given how little I'd prepared for this particular assessment, I was mainly casing. I finished both games with time to spare though, normally I'm rushing on the last screen barely reading things! The hour I spent actually felt like it was enough preparation.

I'm experienced/switching careers so it's been ages since I've touched ANYTHING like this. I was a little nervous going into it, admittedly. This put my mind at rest and was worth every dollar. Massive thanks!

Used it purely for practice with the simulations since I didn't feel using the solvers was right for me. The simulations basically match exactly what the real game asks and look like, but with a different color scheme. I did make it through without the calculators but I'm pretty sure I would have ran out of time without the simulation prep.

FAQ

Questions, answered.

Is this affiliated with McKinsey?

No. Ace the Solve is a service providing independent study aids for the McKinsey Solve ecosystem — it is not endorsed by or affiliated with McKinsey & Company, BCG or any other commercial entity unless otherwise explicitly written.

How does the paywall work?

After checkout you receive an access token with a personalised return link. Open a solver or simulator, confirm the "enter & consume run" prompt, and one run is consumed server-side — you can then re-run within that session as many times as you like. Every product (Ecosystem Solver, Sea Wolf Solver, Sea Wolf Simulation, Sustainable Futures Lab, Redrock Simulation, BCG Quant Simulation) gives you three runs per purchase. If you buy the McKinsey bundle, you get three runs of all five McKinsey tools; BCG Quant is sold separately. Consumed runs cannot be reused.

Does my data leave my browser?

No, data privacy is a big concern and as a candidate you should feel confident that your e-mail, name and any other details will remain private. We do not create user accounts and the entire solver runs client-side. Your assessment data is never sent to a server.

How long will I have access to the solver for?

There's no time limit — your token stays valid until you use it. Once you confirm entry to a solver (or start a simulation run), that run is consumed, but you can re-run within the open session as often as you like. Tokens don't expire, so you can buy now and solve later.

Stop guessing. Start solving.

One payment, one solve, one optimal answer. Get instant access to the Ecosystem Solver, the Sea Wolf Solver, the timed simulation, or all three.
