Logic Masters Deutschland e.V.

Standard sudoku rules do NOT apply. Each cell has an integer value between 1 and 10 inclusive. Numbers cannot repeat in a row, column, or marked 3x3 box, and each number must appear in the finished grid at least 8 times.

White and black dots are standard kropki dots: A white dot indicates the two numbers next to it are consecutive (such as 1 and 2, or 6 and 7). Black dots indicate the two numbers next to it share a 1:2 ratio (such as 2 and 4, or 5 and 10). A 1-2 pair may be indicated by either color. Not all possible dots are given.

Standard odd/even rules apply: Cells with shaded circles must contain odd numbers. Cells with shaded squares must contain even numbers.

Standard killer rules apply: Numbers in a cage cannot repeat. All the numbers in a cage must sum to the small number in the upper left corner, if given.

Hints:

1) Keep track of which numbers are not in a row, column, or box. Each number is only excluded from the grid up to once!

2) If a number is not in a box, then it is not in one of the rows crossing it. The same holds true for columns.
