Mistakes 0 of 5 matched
A patent drawing with numbered callouts pointing at its parts.

How to play

You are looking at a real patent drawing, and you are not told what it is.

  1. Pick a part name from the list.
  2. Tap the numbered callout on the drawing you think it points at.
  3. Three mistakes and you are out.

The names are lifted word for word from the patent’s own text, so they are the draughtsman’s words rather than yours. Finish, and you find out what the thing was and what year it was granted.
