Normal sudoku rules apply. Fog will clear as correct digits are placed. There is a red cage from r3-r9 and c3-c9 in which Japanese sums colorings will take place, with clues given in c1-2 and r1-2. Clues are colored pink, and if there is a cage there, the sum of the run of pink cells is known to be the small digit in the corner * 10 + the value in the cage. So if a cage had a little 1 and a 4 was placed in it, the JSS clue would be 14. If there is no cage, you know there's a run of coloring, but not what it sums to. The clues inside the grid (r1-2 and c1-2) indicate the sums of the contiguous runs found in that row or column that must be shaded. There must be an unshaded cell between runs of the same color. If a row or column is unclued (no pink cells at all), there is no shading in that row or column. Cells joined with a V sum to 5. 4 colored dots in the grid, Green, Red, Blue and Yellow are ratio dots and may represent any ratio from 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, or 1:9. It's up to the solver to determine which dot is which type. A pink line is either Renban (consecutive sequence of digits in any order) OR German Whisper (neighbouring digits differ by at least 5. Each line must be determined individually. A circle is odd.
