Daily — One specimen per category, same for everyone, once per day. Hints are disabled.
Endless — Unlimited practice rounds. Hints available. Period & Difficulty filters available.
Challenge — Like Endless, but one random column is hidden ("Unknown") each round, and hints are disabled.
Time Attack — Pick between a timer of 1, 2, or 3 minutes. Guess as many as you can before time runs out. No hints. Skip a specimen for a time penalty. See your full round breakdown when time's up.
Head to Head — Create a challenge, play a set of 5 or 10 rounds, then share the generated link with a friend. They play the identical sequence, and you both see who won each round by time and guesses.
