There has been no official announcement of Knowledge is Power being delisted, but users first noticed and reported on this title (plus other Sony published PlayLink games) going missing at the beginning of November 2023, the earliest posts being the 1st of November and the 3rd of November.

This is following after the game’s developer Wish Studios being shutdown on the 28th of February 2019, and lack of further support for all PlayLink games by the platform holder/publisher (Sony Interactive Entertainment.) The reasons for the shutdown of the studio are cited as a lack of further funding for PlayLink projects, and no interest from other publishers for different pitches/projects.

The company reports it had been “seeking a publishing deal for one of its two new projects, alongside a search for other funding opportunities”, but was unsuccessful in securing a deal.

MCV News Post – February 28, 2019

Despite the digital removal of this title, the companion mobile app that is required for all gameplay is still currently available on both the Google Play and iOS App stores, although with some caveats.

But it remains in question as to how long the mobile app will be officially supported, due to the nature of how backwards compatibility of apps works across Android & iOS, a device that only runs an Operating System version between the app required minimum and no higher than the OS version available as of the game’s last update would be guaranteed to work with an install (official or otherwise acquired APK.)

PSN Store description
Go head-to-head against your friends and family in this quirky, quick-fire quiz game where all you need is a mobile, a TV, your PS4™ and a brain full of general knowledge, trivia, tricks and tactics…

Part of the exclusive PlayLink for PS4™ range, Knowledge is Power challenges up to six brainboxes, bluffers and guessers to pick up a smartphone or tablet to swipe, type and tap in those all-important answers/random guesses.

  • Battle to the top of the gameshow’s Pyramid of Knowledge, answering questions on a wide range of categories.
  • Vote for quiz categories in which you’ll excel – or veto those you dread.
  • Hurl crazy Power Plays into the mix to slow your opponents down – forcing them to tap through ice or rub away gunk before they can even answer.
