What games are in the current version of McKinsey's PSG?

I know Redrock has suddenly become standard, which of the two other games has it displaced, the Ecosystem game or Plant Defense?

I guess you can probably get them all, but what are the most “typical” ones now in 2023?

Hi there,

Q: I know Redrock has suddenly become standard, which of the two other games has it displaced, the Ecosystem game or Plant Defense? I guess you can probably get them all, but what are the most “typical” ones now in 2023?

Starting from the end of February 2023, McKinsey replaced Plant Defense with Redrock.

If you want to learn more about the game, you can find at the link below the video simulation I created with:

  • 23 videos where you can watch how to crack the Ecosystem Game in 23 minutes (instead of the recommended 35), resist 25+ turns in the Plant Defense (instead of the minimum target of 15) and prepare for the 4 Phases of the new Redrock Study (including tips for the 10 cases)
  • Automated Excel with Formulas to build a food chain in the Ecosystem game in 16 minutes
  • 152-page PDF guide with all 6 possible games and how to crack each of them

You can access immediately the video simulation at the following link:

If you have any questions about the game please drop me a message, I will reply within 12 hours.

Best,

Francesco

Hi there,

The Plant Defense has been replaced.

That said…be careful. Redrock came across “suddenly” as you noted.

It can just as quickly disappear.

Plant Defense could just as quickly come back.

And a whole new game could just as quickly appear.

Learn how to read instructions for these games (and other similar ones). The most common are Ecosystem and Redrock….for the moment.

Hi there,

I think this is an interesting question that may be relevant for many people. I would be happy to share my thoughts on it:

  • First of all, based on the experience of my coachees and my personal network, McKinsey has completely replaced the Plant Defense game with the Red Rock study, meaning you will most likely need to solve both the Ecosystem game and the Red Rock study.
  • However, as you mentioned, since the Red Rock study appeared unexpectedly, it could also disappear just as quickly. As such, I would advise you to still prepare for the Plant Defense game.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

Best,

Hagen

Redrock replaced the plant defense. So it is ecosystem first for 35 minutes and then redrock for 35 minutes. As mentioned, you can get any but that seems to be pretty standard.
