Blue Prince is an intricate puzzle game set in a mansion with impossible architecture.
The game involves building the manor by drawing from a pool of floorplans and discovering the 46th room.
While not marketed as cooperative, Blue Prince naturally lends itself to co-op play, allowing one person to take control and another to jot down clues.
The article highlights that many single-player puzzle games can be enjoyed as couch co-op experiences, mentioning several favorites including Lorelei and the Laser Eyes, The Talos Principle 2, and The Rise of the Golden Idol.
