Normal sudoku rules apply. Every run of five digits on the yellow line contains a digit from {1,6}, a digit from {2,7}, a digit from {3,8}, a digit from {4,9}, and the digit 5. The grey line consists of one or more contiguous groups of cells, each of which sums to 10. These groups of cells cannot overlap. Digits an equal distance from the centre of the purple line must sum to the digit in the centre of that purple line. Adjacent digits along the green line must differ by at least 5. Digits on the pink line form a set of consecutive integers in some order.
