Logic Masters Deutschland e.V.

German Whispers and Numbered Rooms both absolute S tier constraints, so why not combine them? Consensus testing estimate was 2 to 3 stars. Good luck!

• Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box
• German Whispers: Adjacent digits on a green line must differ by at least 5
• Numbered Rooms: Clues outside the grid give the digit to be placed in the Nth position in that row or column, where N is the digit in the first cell. Numbered rooms are to be determined by the solver

Numbered Rooms Example
If you are new to numbered rooms they can look a bit intimidating. This image should clarify how they work. The 3 in R1C1 is saying to place 7 in the 3rd position, i.e. R1C3. The 6 in R1C9 is saying to place the 9 in the 6th position, i.e. R1C4. The 2 in R1C5 is saying to place 8 in the 2nd position, i.e. R2C5.
