Sudoku is Then One Foggy Christmas Eve by Panthera, App variant is DOMINO


Santa needs your help to deliver his gifts in the snowstorm!! Place the digits from 1-6 twice in every row, column and region. Normal Japanese sums rules apply. Colors used in this puzzle are beige, brown, dark brown, red and grey/black. The squares outside the grid indicate the order of runs of contiguous cells found in that row or column that must be shaded the color of the clue. The number in the clue, if given, indicates the sum of the cells in the run. There must be at least one unshaded cell between runs of the same color, though there is no need between runs of differing colors. All runs are given. White snow dots separate consecutive digits.
