Logic Masters Deutschland e.V.

Think I found myself a new hobby, hope you enjoy!

Rules:

Normal Sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box.

Thermometers: Digits along a thermometer must strictly increase from the bulb to the tip.

Killer cage: Digits in cages must sum to the number given in the corner.

Quadruple: Digits in the white circels must appear in the four surrounding cells.

XV: Cells separated by a V must sum to 5.

Kropki dots: Cells separated by a white dot are consecutive, cells separated by a black dot have a 1:2 ratio. Not all dots are necessarily given.

Arrows: Digits along an arrow must sum to the digit in the circle.

Diagonal: Digits along the marked diagonal must not repeat.

However! One of these constraint types is false and must not be true. If there is more than one of that constraint type non of them can be true. It is up to the solver to deduce wich of the constraints is false.
