Flags Make People Click

By Rehan Sayyed, SRT Corporates · Published

A button that adds one to a number is a small thing. Put a flag beside it and something changes. People who would not press a button for themselves will press it for a country.

The cat that started a contest

Popcat began as a meme in October 2020: two pictures of a cat, one with its mouth closed and one edited so that its mouth forms an "O". On 11 December 2020 three students at the University of Sheffield launched a website built on it. Click the cat and its mouth pops open with a sound. Every click also counts toward your nation's rank on a leaderboard.

That last detail turned a toy into a contest. In August 2021 Taiwan became the top nation, and then Thailand overtook it. As of August 2023 the top three were Hong Kong, Taiwan and Thailand.

Flags on a shared canvas

The same instinct shows up where nobody asked for it. Reddit's r/place gave users a blank canvas and one pixel at a time (see A Short History of the Internet Doing One Thing Together). There was no leaderboard and no mention of countries. Even so, much of the artwork in 2022 was country flags, as it had been in 2017, and many of the early artworks in 2023 were flags again.

What a flag adds

These are our own observations, not research findings.

How Click With The World does it

Every click here counts twice: once for the world total and once for a country.

What we left out

A few choices were deliberate.

The rule underneath is the same for everyone: one click adds exactly one, to exactly one country, with a short pause before the next.

Two numbers at once

A country table on its own is a contest. A single world total on its own is a shared project. Having both on one page means every click does two things: it moves your flag up, and it moves everyone toward the next milestone. The rivalry is between countries, but the milestones are reached together.
