Logic Masters Deutschland e.V.

Rules:

Sudoku: Normal sudoku rules apply, i.e., each row, column, and 3x3 box must contain digits 1-9 once each.

Region Sum Line: Digits on the blue region sum line have an equal sum within each box it passes through. (Note: 6 squares at R34C123 are all on the region sum line.)

German whisper line: Two cells connected by green German whisper lines must have a difference of at least 5.

Renban lines: Purple renban lines contain a set of consecutive digits in any order without repeats.

Parity line: Every pair of consecutive cells along the red parity line must contain an even digit and an odd digit.

Kropki dots: Digits separated by white dots are consecutive. Digits separated by black kropki dots have a 1:2 ratio. Not all dots are given.

Arrow: Digits along the arrow sum to the number in the arrow's circle.

Ohm's Law: The grid contains an electric circuit with a power supply of V Volts and a resistor of R Ohms. Hence, a current of I Amperes is flowing through the circuit, where I = V/R. These values must be determined by the solver using the following information: - The cage labeled V contains the 3-digit number V, reading from top to bottom. - The cage labeled R contains digits that sum to R. This sum is also equal to the region sums of the region sum line. - The arrow's circle contains the current I.

+ and - signs are purely cosmetic and do not contribute to the solution path.

Sudoku: Normal sudoku rules apply, i.e., each row, column, and 3x3 box must contain digits 1-9 once each.
