You can choose to get 1-5 random CAPTCHAs out of your favorite selection or complete several CAPTCHAs in a row with the multi-CAPTCHA feature. Other features include Spin around, Fun with Flags to recognize flags, Zombie Walk to walk X meters, Let it be light to put your phone to a light source, Mirror Text to read and write mirror-flipped wisdom texts, and CAPTCHA CAPTCHA, which is the ultimate CAPTCHA that requires you to solve a web-like CAPTCHA. More features are expected to come in the future.
