(Published on 7. April 2024, 05:00 by Will Power)

Normal Sudoku rules apply. KROPKI PAIRS- Numbers with a black dot between them (meter needle) are in a ratio of 2:1. Numbers with a white dot between them are consecutive. Not all possible dots are shown. DUTCH WHISPERS(+)- Numbers on red lines (meter body) are at least 4 apart from their neighbors on the line. ALL NUMBERS on red lines are UNIQUE TO THAT LINE. No lines have any numbers in common with the other two lines. MIN/MAX- Cells with (Greater than) pointing outward are greater than all adjacent cells. Cells with (Less than) pointing inward are less than all adjacent cells. LITTLE KILLER- Numbers outside the grid are the sum of the indicated diagonal.

Fun puzzle! Thanks!

@MarthaB Thanks for the kind comment. As my resident mathematician, have you attempted my "Sequence Master" puzzle (not sudoku) from a long time ago? Only 5 have solved it so far. Peace to you. -Will Power
