In my haste to get this sudoku variant built, play-tested and submitted by the WSGA puzzle deadline, I not only misspelled DEADLINE, I neglected to draw the numbers. Luckily, the puzzle is solvable with these rules:
-
Each number is used once within a row or column.
-
Each colored region (denoted by a thick line) contains the numbers 1 through 9.
-
A white dot means the difference between the adjacent numbers is 1.
-
A black dot means one cell is twice its adjacent.
-
The mathematically astute will notice that the dot between one and two could be either color. Because this isn't intended to be Opening Shots difficult, these are denoted by a half-coloured dot. (You're welcome!)
-
The absence of dots is very important.
For example, if you had a 4x4 matrix with this:
with the numbers 1 through 4, the only solution could be:
