A strange little side quest
The rules may be simple on screen, but the backstory around Ninja Shape is anything but tiny. Arthur Wynne published a diamond-shaped 'Word-Cross' in the New York World on December 21, 1913; the name later shifted to 'Cross-Word' and then 'crossword'. The same trail leads to another fact: Space Invaders, released in 1978, helped push video games into mainstream popular culture. Grombi files that under: small game, surprisingly large backstory.
