Chock-a-Block

Normal sudoku rules apply.

• Unique N-Lines: 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.

• The grey perimeter can be used for making notes.
