Round 1: Diagnose
-
Read the case
Start with the opening history and any image. Tap an image to zoom in on scale, borders, hair, and pigment.
-
Make a guess
Start typing and pick the diagnosis from the list. Small typos, common names and abbreviations still find it, and a guess that isn't on the list never costs you a turn.
-
Misses unlock clues
Each wrong guess turns gray and reveals the next clue. Some clues are new images of the condition, shown alongside the first.
-
Solve it, or see the answer
Get it in five or fewer and your tile turns green. Either way you’ll see the diagnosis, the teaching points, and your stats.

Round 2: Spot it again
Your case images stay at the top. Below them, choose which new image shows the same condition. Pick a look-alike and you’ll see what it actually is and how to tell them apart. Keep going until you find the match.
