Indextropy (with ChinStrap)
(Published on 12. February 2025, 21:04 by sujoyku)
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
For each set of 3 lines with the same color (and line styling), 2 of those are index lines and one is an entropic line.
- Index Lines: Each index line has an invisible diamond (to be determined by the solver) at one end of the line. The digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears. For example, 3214 is a valid index line, the 1st digit, 3, indicates that the 3rd digit is a 1, and so on.
- Entropic Lines: Any three adjacent digits along an entropic line must contain one low digit (1, 2, or 3), one medium digit (4, 5, or 6) and one high digit (7, 8, or 9).

Solution code: Column 5 from top to bottom (9 digits in total)
