Delta Rune

Rules:

  • Classic Sudoku: Every row, column and 3x3 box must contain every number from 1 to 9.
  • Arrows: Numbers along an arrow sum up to the total in the circled cell.
  • Palindrome Lines: Digits along a grey line read the same backwards and forwards.
  • Region Sum Lines: Box borders divide a blue line into multiple segments which have the same sum.
  • Renban:All digits along a purple line must form a consecutive sequence (in no specific order).
  • German Whispers: Every two consecutive digits along a green line must have a difference of at least 5.
  • Counting Circles: Any digit in a circle indicates exactly how many circles contain that digit (arrow circles are NOT included).
  • Kropki: Two digits separated by a white dot are consecutive; two digits separated by a black dot have a 1:2 ratio.

Solution code: Row 8, left to right.

Love the video game reference, good setting! Definitely 1-1.5*, does take some work in top boxes but flows well. Thanks!

Maybe I missed something obvious but the upper boxes felt exceedingly difficult for a 1*
