About Zebritis

Zebritis is a free daily rare disease quiz game where obscure knowledge finally pays. Each prompt, like 'Name a cause of finger clubbing', has a long list of correct answers. Common answers score 1, rarer ones more, true zebras 10, and the single rarest answer, the unicorn, 20. Wednesday is Super Zebritis, with five prompts instead of three.
