Logic Masters Deutschland e.V.

Place the digits 0-9 once each in every row, column and box. To do this, 1 cell in each row/column/box is a Schrödinger cell, which contains 2 digits. The value of this cell is the sum of the contained digits.

The digits 1-9 each appear exactly twice in the Schrödinger cells, and no two Schrödinger cells contain an identical pair of digits.

• Values separated by a black dot are in a 1:2 ratio. Values separated by a white dot are consecutive.
• Adjacent cells on a green line differ in value by at least 5.
• Adjacent cells on an orange line differ in value by at least 4.
• Cells on a purple line form a non-repeating set of consecutive values (however, digits may repeat on the line if one is in a Schrödinger cell).
• Digits in a cage may not repeat (but values may), and must sum to the total given in the top left corner.
• Values separated by a 'V' sum to 5.
• Values separated by an 'X' sum to 10.
• Cells containing a grey circle must have an odd value.

Lines do not branch, and lines of the same type do not cross.

Additionally, the grid is partially covered in fog. Placing correct digits will clear the fog from the surrounding cells, potentially revealing more clues. No guessing is required.
