Sukrokuro
Fill a Latin grid and satisfy the black-cell sum clues.
Controls
Fill every row and column with the digits 1 to 9 once each. Each black cell shows a sum for the white run to its right or below it; the digits in that run must add up to the clue. Kropki dots mean consecutive digits, and the puzzle has no given numbers, so use the sums and dots to deduce the grid. Tap a cell, then a digit, and use Clear to reset.
