Race the bots

A room on this device with bots in it. Same rules as a live room.

How to play
  1. A tracing appears with a short history. The bar sweeping across it is your clock.
  2. Type the diagnosis and press Enter. Abbreviations work (AF, CHB, WPW, LBBB, PE, HCM…) and small typos are forgiven.
  3. A right call scores 100 plus up to 100 for speed. In a room, the first right call gets 25 more. Each wrong call costs 10; “close” answers cost nothing and tell you to be more specific.
  4. Then pick the next step from four options for 50 more.
  5. After each tracing you see it annotated, with the explanation and references.
