If it’s Pi Day, that means…

by

Brainfreeze Puzzles must have a new Pi Day Puzzle up — woo hoo!!!!!

The Rules are to fill in this pie-shaped circle so that the numbers 1 through 12 appear:

  • exactly once in each double-wedge of the same color,
  • exactly once in each pair of opposite wedges, and
  • exactly once in each ring around the center.

As in previous years, they are having a contest for correct entries (information on this website and this pdf file), so no hints or solutions are to be posted in the comments until the contest closes on June 1.  [If/when they print a solution, we'll post a link to it.]

If you missed Brainfreeze’s earlier puzzles, here are the ones from:
