r/place: one tile per user every five minutes — 1M people paint a 16M-tile canvas in 72h
For April Fools' 2017 Reddit opened a 1,000×1,000 canvas; one tile per account every five minutes turned communities into the internet's biggest shared artwork.
What it had to solve
Reddit engineers wanted an April Fools' project with a fixed April 1 launch date, a team of only three or four engineers, and rules simple enough that the community itself would generate the fun. Earlier years had shipped one-day experiments; r/place was given 72 hours on a completely blank canvas.
How it works
On 31 March 2017, Reddit replaced its front page with a blank 1,000×1,000 pixel canvas and told logged-in users they could place one colored tile from a 16-color palette every five minutes. The April Fools' project had a hard launch date, a team of three or four engineers, and a simple motto: "Individually you can create something, together you can create something more."
The five-minute per-account cooldown made drawing anything alone nearly impossible, so the game was really about coordination: subreddit communities formed alliances, drew borders, defended their art against vandalism, and fought territorial wars over 72 hours. The final canvas was a dense patchwork of country flags, memes, game characters and a Mona Lisa — plus an independent "atlas" documenting every piece that survived.
The numbers: 1.1 million unique users placed 16.5 million tiles before the experiment ended, enough to cover the board more than sixteen times over. In 2022 Reddit repeated it with more colors and daily canvas expansions: 10.4 million users placed 160+ million tiles from 236 countries and territories, with 943 million screenviews over four days.
Why it lands
- One tile every five minutes makes solo drawing useless, so the only way to create anything is to coordinate — the rule manufactures cooperation.
- A blank canvas plus a deadline creates a zero-sum game of territory, so communities compete and negotiate with drama that outsiders can watch.
- The output is a time-stamped artifact of the community itself, and the timelapse turns the whole conflict into a watchable story.
- Entry costs almost nothing — a logged-in account — and the result is legible to anyone, so participation scales from individuals to nation-sized factions.
What it did
1.1 million unique users placed 16.5 million tiles in 72 hours, per Reddit's own engineering write-up (the company's summary rounds this to over 1 million users and about 16 million tiles). In 2022 Reddit repeated it with more colors and daily canvas expansion: 10.4 million users placed 160+ million tiles from 236 countries, with 943 million screenviews over four days.
What you can take
One tile every five minutes makes solo drawing impossible, so alliances and turf wars — not the art — become the content; the constraint itself is the creative act.
Since then
r/place became a recurring platform ritual: Reddit brought it back in 2022 with more colors and daily canvas expansion, and the community kept building tools around it — an independent Atlas of every artwork and timelapses of the canvas's evolution. The one-pixel-per-five-minutes format has been borrowed by other communities and brands as a template for mass collaboration.
