"A Redditor found the easter egg by typing "text adventure" into google.com and opening Chrome's javascript console. Beneath a warning reminding users never to manually copy and paste anything nefarious into the code, the console asks: "Would you like to play a game? (yes/no)".While not exactly complex, the story - which is a mission to locate the missing letters of the Google logo by way of simple text directions - requires you to navigate by way of a series of directional instructions, plus the actions "grab", "inventory", and "use". You can also ask "why", and bring up all commands available to you via "help"."
