For this Sudoku Variants Project I have planned to publish a unique Sudoku variant every week.
Encaged 4
Inspiration for this type comes from Sudoku Grand Prix 2026 Round 4 (Switzerland).
Solve online in Sudokupad.
I will see how long it takes before I am running out of ideas.
Apply classic sudoku rules.
Each digit 4 may have only odd digits as its horizontally and vertically neighbours.
Solution code: Row 3
