2017 experiment The final product of the original 2017 r/place experiment In the 2022 edition, the canvas was eventually expanded to four million (2000 x 2000) pixel squares, and the palette gradually gained sixteen more colors for a total of 32. In 2017, the waiting time varied from 5 to 20 minutes throughout the experiment, and the user could choose their pixel's color from a palette of sixteen colors. The experiment, on both occasions, was based in a subreddit called r/place, in which individual registered users could place a single colored pixel (or "tile") on an online canvas of one million (1000 x 1000) pixel squares, and wait a certain amount of time before placing another. On the 1st of April 2022, Reddit began a reboot of the experiment that lasted for four days. The experiment was commended for its representation of the culture of Reddit's online communities, and of Internet culture as a whole. Over 1 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. It was ended by Reddit administrators about 72 hours after its creation, on 3 April 2017.

The idea of the experiment was conceived by Josh Wardle. 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). Registered users could edit the canvas by changing the color of a single pixel with a replacement from a 16-color palette.

The 2017 experiment involved an online canvas located at a subreddit called r/place. R/place was a collaborative project and social experiment hosted on the social networking site Reddit on April Fools' Day 2017 and repeated again on April Fools' Day 2022.
