Portal, The Board Game (2015) — When a Portal Stopped Being a Hole and Became "Adjacent"
Valve's Portal has a board game, released in 2015. Cardboard panels cannot hold a fall or carry momentum, so something had to go. Reading the rules closely shows exactly what went and what stayed: all that survived is the power to make two distant chambers adjacent. That alone still wrecks how you read a route. Which means anyone adding portals to a grid puzzle can test the idea with that single rule first. A translation for people who build digital puzzles.
