Note: The first batch of printed newsletters had a misprint on the page 7 puzzle (“Pascal’s Puzzle Tree”). This error has been corrected for future batches, including in the link above. To make sure you have the correct version of the puzzle, look at the last row on the tree. Both “462” cells should be touching. If there’s a space between them, please print out the fixed version.

For our avid puzzle-solvers, we sincerely apologize for any potential frustration caused by this error!
