CAPTCHA test / Showroom
CAPTCHAs built to be talked about
One-off builds by developers and designers: a CAPTCHA that makes you play DOOM, one that makes you sight-read piano. Brilliant, unforgettable, and impossible to put on your own site. We describe them, show our own screenshots and link to the original.

Two to start, more as we capture them. Same card as everywhere else; the status is what makes it a showroom piece.
DOOM CAPTCHA
Guillermo Rauch, Vercel
Asks: play a WebAssembly build of DOOM and defeat three enemies with 50 bullets and 100 health. Why it matters: it makes the cost of a challenge visible - minutes, not seconds. Cost to a visitor: however long it takes you to win. Original: doom-captcha.vercel.app.
Worst. CAPTCHAs. Ever.
Michael Hsu
Asks: sight-read and play a melody, shoot ducks against the clock, scratch three boxes, or win two hands of blackjack before the login form opens. Why it matters: "creative ways of how NOT to do things", in the author's words. Original: worst-captchas-ever.vercel.app.
