Objective / Rules - The clues are on the right and across the bottom and are the totals for the respective rows and columns. - The numbers across the top and on the left are the values for each of the squares. - The first square in a row is worth 1, the second 2, the third 3, and so on. - The first square in a column is worth 1, the second 2, the third 3, and so on. - Marking a square in Blue will add that square's value to both the row's total and the column's total. - E.g. if the second and fourth square in a row were Blue, the row's total would be 2 + 4 = 6. - Find all of the Blue squares such that all of the totals match the clues. - You can mark squares in White for those that cannot be Blue. - Numbers in brackets indicate the row/column totals so far (unless the total is zero).
