Logic Masters Deutschland e.V.

Rules:

Normal 0-8 sudoku rules apply - Place the digits 0-8 such that no digits repeat in any row, column, or 3x3 box.

Dynamic fog - The grid is covered in fog. Entering correct digits clears the fog, revealing all symbols and constraints (including V, X, etc.) hidden within it.

Index - On a blue line, the digit in the Nth cell along the line (starting from the diamond) indicates the position on the line where the digit N appears.

Thermometers - Digits along a thick grey line increase from bulb to tip.

Anti-Knight - Cells separated by a chess knight's move may not contain the same digits.

Killer cages - Digits inside a cage sum to the total given in the top left corner of the cage without repeats.

V-Pairs - Cells separated by a "V" must sum to 5.
