How to Play

Labdle is a daily diagnostic game. A fictional laboratory panel comes back one result at a time — your job is to name the diagnosis.

Rules

• Every day at midnight (Toronto time) a new case is released. Everyone gets the same case.
• The first result is on the sheet immediately, with units and reference ranges.
• Type a diagnosis and pick it from the suggestions — free text isn’t accepted.
• Each incorrect guess releases the next result, up to five.
• Your score is the number of results you needed, out of five.
• After the case ends you’ll see the interpretation, an explanation, and teaching points.

Archive

Every previously released panel stays available in the Result History. Archive play counts toward cases played, but only completing the daily case on its day maintains your streak.

Accounts

No account is needed to play — guest progress stays in this browser. A free Rounds account keeps streaks and statistics in sync everywhere, and works on every Rounds game.

Education only

All cases are fictional teaching material. Nothing here is clinical advice.
