Shows the answer, then moves on
  • Each name appears in turn. Click its list, or press its number.
  • The groups never move, so the number keys are quick.
  • Skip (0) sends a prompt to the back of the queue.
  • Pause whenever you like (Esc). The board hides while the clock is stopped.

Press the group each name belongs to. The groups appear when you start.

About this quiz

Every name is read from a list Ribbia already holds, and a name that sits on two of these lists is never dealt, so each one has a single right box.

  • A wrong pick shows the right group for a moment and the round moves on.
  • The full run plays all 73 names with its own best score.
  • The first round of the day is the same for everyone.
