Rule Out
Clues
Pick a diagnosis from the list. A miss shows whether you matched the body system, the type of problem and the timing, and unlocks the next clue.
A daily diagnosis game you solve by ruling things out
Rule Out gives everyone the same medical mystery each day. Name the diagnosis in six clues or fewer. Each miss shows whether you matched the body system, the type of problem and the timing, so you work toward the answer the way clinicians do. More than 350 original cases, each linked to a free study guide with cited sources.
What is Rule Out?
Rule Out is a free daily diagnosis game from Progress Note. Everyone gets the same medical mystery each day. Read the first clue, name the diagnosis, and each miss unlocks another clue, up to six.
Who is it for?
Pre-med, nursing, PA and medical students, and anyone who likes a medical puzzle. Clues start with the patient's story and end with classic test results, so you don't need clinical training to solve most cases.
Is it free? Do I need an account?
It is free and needs no account. Your streak and stats are saved in your browser.
How is it different from other medical guessing games?
Every miss tells you whether you matched the body system, the type of problem and the timing, so you narrow the diagnosis the way clinicians do: by ruling things out. Every answer links to a free study guide with cited sources.
Can my class or club play together?
Yes. Start a league from the game page and share its code. Members compete on a private weekly leaderboard. Run a Discord or Slack? Get the daily case posted in your channel.
When does a new case come out?
A new case arrives at midnight. You can also play past cases from the archive.
