Rules:
Fill the grid with the numbers 1–25 exactly once each.
All rows, columns and diagonals sum to the same total.
Additionally, the center 3x3 box and the blue diamond are a magic square as well with all rows, columns and diagonals summing to the same total.
Digits on a coloured line sum to either 20 or 26.
Tip: use pencilmarks to write any number above 9. For solution check: enter only the last digit of a two digit number
Happy 2026
