A strange little side quest
The rules may be simple on screen, but the backstory around Football Headz Cup is anything but tiny. The penalty kick entered football's laws in 1891 and was nicknamed the 'kick of death' in its early days. And then there is this: Archery was already on the Olympic programme in 1900, boxing joined the modern Games in 1904, and basketball became a medal sport in 1936. That long chain of experiments is part of why football still feels fresh when a game finds the right twist.
