Hidden Year of the Snake
(Published on 22. December 2025, 16:42 by logicanimal)
Rules: Math Path variant
1. Insert the numbers 1-25 into the grid so that the ordered sequence forms a connected path. The path may travel diagonally and may cross itself.
2. Some bolded regions contain a math operation (- or x). Applying the operation successively to the numbers in its region, starting with the largest number, must produce one of the following results: 20, 25, -20, -25.
You can solve the puzzle here.
This is one of 12 disjoint puzzles I made this year, with varying styles/difficulties, themed around snakes and 2025. Enjoy!
Solution code: Enter the numbers in row 2 and 5.
