- Normal Sudoku Rules apply
- Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.
- Palindrome lines: Digits along the grey lines read the same forwards and backwards. (e.g. 1534351)
As well as setting puzzles, I also solve puzzles on YouTube. Please check it out!
Solution code: Column 9

I loved this puzzle so much that I was sad when I’d solved it!

A really fun puzzle, alas I eventually had to switch letter tool rather than colouring as I couldn't work out a good scheme for box vs cell restrictions with colours :D
