A Matter of Dots and Lines
by FullDeck and Missing a Few Cards Open on SudokuPad
- Kropki dots
- Region sum lines
- Renban lines
The brief
**Sudoku, Sum Lines, Renban Lines, Kropki Pairs** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Sum Line: Box borders split blue lines into sections, and the digits on those sections must sum to the same value. If a line has multiple sections within a box, these sections are summed separately. - Renban Lines: Digits along a pink Renban line must form a set of non-repeating consecutive digits in any order. - Kropki Pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given. Note for clarity: the thinner lines contained completely within boxes 2, 4, 6, and 8 are renban lines. The other, thicker, lines are region sum lines. Subscribe to our mailing list to receive a weekly email with all of our puzzles from the past week: https://missingdeck.net/mailing.html
