Logic Masters Deutschland e.V.

An homage to the German nonsense poet Christian Morgenstern.

Standard Sudoku rules are in effect, i.e., each row, column, and 3x3 box must contain one each of the digits 1-9.

A V between cells means that these digits sum to 5, an X that they sum to 10. Not all Xs and Vs are given.

Cells along lines between two filled circles must have values which lie between those in the circles. That is, between a circled 2 and 7 you may only place 3,4,5, and/or 6. Digits may repeat along a between-line.
