Seven Lines

(Published on 13. January 2026, 21:06 by StephenR)

This is my first puzzle - I don't think I've made any howlers but please leave a comment if you spot anything. I've marked it as two stars, but wouldn't be surprised if some rate it at one star.

However many stars, I hope you enjoy it.

Rules

  • Normal sudoku rules apply.
  • Digits in the larger white circles must appear at least once in the four surrounding cells.
  • Digits on a pink line form a set of consecutive, non-repeating digits in any order.
  • Digits on the blue line have the same sum in each box the line passes through.
  • A black dot separates digits where one is double the other.
  • A smaller white dot separates consecutive digits.
  • Digits in the cage sum to the number in the top-left corner.
  • SudokuPad

I was surprised to see that it was your first puzzle, it was very nice, but I confirm the 1* for difficulty (which is not a bad thing at all)
