Logic Masters Deutschland e.V.

Another co-work with my son Till. He did the design, I tought of some (hopefully) clever challenging interactions. Leave a comment if you enjoyed it.

Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Thermometers: Digits on Thermos are strictly increasing from bulb to tip.

Kropki pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.

German Whispers: Usually shown as green lines, adjacent digits along a German Whispers line must differ by at least five.

Renban line: Usually shown as purple lines, digits along a Renban line must form a set of non-repeating consecutive digits in any order.

Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.

Odd: The cell marked with a grey circle contains an odd digit.
