A closer look
You literally had to wear a baseball cap backwards to win. In the classic 1983 board game Scotland Yard, the player controlling the fugitive Mr. X receives a physical cardboard visor in the box. This wasn't just a quirky fashion statement; it was a crucial mechanical balancing tool. Because Mr. X tracks their hidden movement on a secret pad, their eye movements across the physical board could accidentally telegraph their exact coordinate to the investigating players. The visor blocks their line of sight from the other side of the table, creating a brilliant, lo-fi solution to asymmetric information bleed.
