Normal sudoku rules apply. ALL lines in the grid are N-Lines. Each N-line is composed of one or more non-overlapping sets of adjacent digits, each of which sum to N. Every line has a different N value. Coloured lines (not including the grey ones) each have an additional rule: • Renban (pink): Digits on a pink line form a non-repeating consecutive set, which can be arranged in any order. • Even Sum Lines (darker blue): All the digits on a darker blue line sum to an even number. • Prime Lines (purple): Adjacent digits on a purple line sum to a prime number. • Anti-Kropki Lines (red): No two digits anywhere on the same red line are consecutive, or in a 1:2 ratio (but they may repeat). • Same Difference Lines (turquoise): Each pair of adjacent digits on a turquoise line have the same difference. This difference must be determined for each turquoise line.
