Pseudoscience
- Whisper lines
- Renban lines
- Nabner lines
The brief
- Normal sudoku rules apply.
- In each row, column and box there is exactly one 'pseudo cell.'
- The digits 1-9 each appear once in a pseudo cell.
- The real value of a pseudo cell (for the purposes of the coloured lines) is determined by multiplying its row number by its column number. Eg; if there is a pseudo cell in r6c3, it has the value of 18, regardless of which digit appears in that cell.
GERMAN WHISPER: The values of adjacent cells on a green line have a difference of at least 5. RENBAN: The values of the cells along a purple line form a non-repeating consecutive set, which can be arranged in any order. NABNER: The value of a cell on a yellow line may not be consecutive with (or the same as) any other values on that line. REGION SUM: The value of cells within each 3x3 box along a darker blue line sum to the same amount. SAME DIFFERENCE: The values of adjacent digits on a turquoise line always have the same difference. DIFFERENT DIFFERENCE: The difference between the values of adjacent cells on a peach line must be different for every pair of adjacent cells on that line. Eg: if there are two cells with values of 7 and 9 next to each other on the line, then cells with values of 4 and 6 may not appear next to each other on the same line (as both pairs would have a difference of 2.)
