14. Hide and Seek
Hide and seek is a much beloved game by children all over the world so it’s no surprise that somebody had the idea to turn it into an official sport. In fact, a sports scientist by the name of Professor Hazaki has been lobbying for the “sport” to be included in the Olympics. Hide and seek sport version requires 2 teams of 7 players each to hide and seek within a 65ft x 65ft pitch in a 10-minute game.
