Logic Masters Deutschland e.V.

Normal Sudoku Rules apply.
Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.

Thermometer
Digits along each thermometer must increase starting from the bulb end.

Killer Cages
The digits in a cage must sum to the number printed in its corner. Digits may not repeat within a cage.

Inequality
Cells on either side of the inequality symbol must have values that abide by the indicated relationship.

Kropki
A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are given. Extended Kropki: In this puzzle the 2:1 ratio can include double digit numbers (i.e 9 and 18 or 18 and 36). These numbers read from left to right or from top to bottom. Both Sides on a dot have the same orientation (both are horizontal (-) or vertical (|)). Every cell can be part of multiple two digit numbers (ie if r8c5/r8c6 would be a 64 and r8c7/r8c8 would be 32 it is possible for r9c8 to be an 6 forming a 12 with r7c8/r8c8). These rules may only count for one and double digit numbers!
