place was a recurring collaborative project and social experiment hosted on the content aggregator site Reddit. Originally launched on April Fools' Day 2017, it has since been repeated again on April Fools' Day 2022 and on July 20, 2023.

The 2017 experiment involved an online canvas located at a subreddit called r/place. Registered users could edit the canvas by changing the color of a single pixel with a replacement from a 16-color palette. After each pixel was placed, a timer prevented the user from placing any more pixels for a period of time varying from 5 to 20 minutes (depending on whether the user had verified their email address).[1][2] The idea of the experiment was conceived by Josh Wardle.[3][4]

Over a million users edited the canvas, placing a total of approximately 16 million pixels, and, at the time the experiment was ended, over 90,000 users were actively viewing or editing the canvas. The experiment was commended for its representation of the culture of Reddit's online communities, and of Internet culture as a whole.[5]
