Logic Masters Deutschland e.V.

This is our first time creating a puzzle, feedback is appreciated :).

• Normal sudoku rules apply.
• Killer cages: digits in a cage sum to the clue and do not repeat.
• Renban (purple lines): digits on a line form a set of consecutive digits, in any order.
• Thermometers: digits increase strictly from the bulb (the grid centre).
• White dots: the two digits differ by 1. Black dots: one digit is double the other. Not all dots are given.
