Unlike a normal CAPTCHA designed to filter out robots, this one filters out humans!
In order to pass you must be a robot (or insanely fast at mental math). If you want to try actually solving the problems, you can modify the timer duration in the state of the Captcha class.
Made with React + Popper.js (warning: first time I've used these).
- 2 correct answers in a row required.
- The following new challenges are added:

- Volume of a rhombicosidodecahedron
- The pi challenge now requires the sum of many digits rather than a single digit.
- The exponent challenge is disabled.
- The colours on the timer now match the page colour scheme.
