Place a digit from 1-9 in each cell of the main 7x7 grid. Digits may not repeat in a row, column or 3x3 box of this grid. The grid contains nine 3x3 boxes, which overlap at the dashed lines. Clues in pills refer to the digits missing from the associated row or column, but pills do not need to be filled. Thick purple pills are X-sum clues, i.e. the digits missing from that row or column can form a 2-digit number, which is the sum of the first X digits from the direction of the pill, where X is the first digit seen. The digits missing from a row with a pill containing a black dot are in a 1:2 ratio (ie one is double the other); The digits missing from a row with a pill containing a white dot are consecutive; The digits missing from a column with a pill containing an X sum to 10.
