What is Draw a Perfect Circle?
Draw a Perfect Circle is a one-move game by Neal Agarwal, released on neal.fun on January 6, 2023. There is a dot in the middle of the screen. You draw a circle around it in one stroke, and the game tells you how close it is to a mathematically perfect circle as a percentage, colouring the parts of your line that wobbled.
It went viral almost immediately. Players posted scores on Hacker News and TikTok, trading results in the high 90s and arguing about the best technique. It is the kind of game you can explain in five words, and that is exactly why it spreads: everyone thinks they can draw a circle, and the score proves otherwise.
