Arithmetid Quiy
(Published on 19. June 2026, 16:30 by mnasti2)
A little bit harder Knapp-Daneben inspired follow-up to Arithmetic Quiz and Arithmetic Quiz Fillomino. Hope you enjoy!
- Normal sudoku rules apply: Place the digits 1-9 exactly once each in every row, column, and 3x3 box.
- Off-By-One Equations: Complete each equation in the grid so that the right hand side is exactly one greater or one less than the value of the left hand side, using standard arithmetic operations. Two-cell pills represent two-digit numbers.
- Adjacent digits along a red line differ by at most 2.
Solution code: Enter row 9 (left-to-right, 9 digits)

Definitely 4* for me as well, and a total delight. Thank you for failing me!

As soon as I saw your name, I knew that I had to solve this. (I use the previous one with my students at the end of the school year, and they always ask "is there another one". And now there is! Thanks a lot.
