Logic Masters Deutschland e.V.

This is the first time I am playing with disjoint sets, so I apologies if it is rough round the edges.

Normal sudoku rules apply (Every row, column, and 3X3 box contains the digits 1-9)

Normal disjoint group rules apply (Cells that appear in the same relative position in their 3x3 box must not contain the same number)

Thermos strictly increase from the bulb to the tip.

Standard killer sudoku rules apply (Digits in caged areas add up to the number in the upper left corner. And digits can not repeat in cages)

Normal Sandwich rules apply(Digits on the outside of the grid indicate the sum of digits between 1 to 9 on the indicated row or column)

Grey squares are even and grey circles are odd
