Question 1

What is DDxam?

Accepted Answer

DDxam is a free daily diagnostic reasoning game. One clinical vignette a day. You lock in a top-3 differential, spend a fixed points budget on history, exam, labs and imaging, and then name one final diagnosis and live with it.

Question 2

Is DDxam free to play?

Accepted Answer

Yes. It is free, it asks for no account, and it runs in any browser on a laptop or a phone.

Question 3

How often are new cases released?

Accepted Answer

A new case goes up every day. Old ones stay in the archive, so a day you missed is still there to play.

Question 4

Who is DDxam for?

Accepted Answer

Medical students and residents who want daily differential-diagnosis practice in a few minutes rather than an evening. It reads like clinical rotations and board-style diagnostic reasoning, so it works as preparation for both.

Question 5

How do you score a case?

Accepted Answer

You start with a points budget and every piece of workup you order comes out of it, which means the fewer tests you needed, the better you score. Get the final diagnosis right and you bank whatever is left. Get it wrong and the case ends at zero.
