Logic Masters Deutschland e.V.

RULES:

• Normal Sudoku rules apply.
• The grid is partially covered in fog. Correctly placed digits will clear fog in that cell and sometimes other cells. No guessing is required.
• Divide the grid into non-overlapping Dominoes. Every cell in the grid belongs to a domino apart from the given digit in the red cage.
• The sum of a domino's digits indicates how many dominoes in the grid share that sum. For example, if a domino sums to 10, there must be 10 dominoes with the sum of 10.
• Domino borders divide each blue line into segments of equal sum.
• Digits joined by a black dot must be in a 2:1 ratio.
