Numeric-Maze challenge
In the following numeric-maze, go to the ‘START’ box and proceed through the maze, following instructions as provided, until you get to the ‘FINISH’ box. What number did you finish with?
Solution:
Good day. When I click on the November 2025 challenge, it gives me the options to see the answers from the previous month’s challenge. However, the answer key does not fit the October challenge. It only gives me the answers to the Numeric-Maze which was not in the October challenge. Am I looking in the wrong place?
