A Rrow of Dots

(Published on 19. January 2026, 21:38 by MathGuy_12)

This was set for Scojo's Setting Saturday prompts. I redeemed this prompt to create a puzzle that highlights the interaction between sum dots and another constraint.

Thanks to lmdemasi for testing!

Rules:

  • Normal sudoku rules apply.

  • Digits in cells touching a gold Sum Dot must sum to the indicated total. Digits may repeat if allowed by other rules.

  • Digits along an arrow sum to the digit in the bulb of the arrow.

  • Digits along a double arrow line have the same sum same as the sum of the digits in the two bulbs. The two double arrow clues are intentionally ambiguous.

Solution code: Row 9 left to right
