This is actually three related Nikoli puzzle types. Place digits from the given set in some of the squares of the grid. Each row and column may contain each digit at most as often as it appears in the set; when not given, the set is assumed to be 1 to 9 once each. Clues for each row and each column correspond to blocks of consecutive digits, similar to clues for Nonograms, but each clue gives the sum of the digits in the block for Japanese sums, the product of the digits for Japanese products, or either the sum or product of the digits for Japanese sums or products
