Logic Masters Deutschland e.V.

• Samurai Sudoku rules apply: normal sudoku rules apply in each of the five grids. Shared boxes conform to both grids' sudoku.
• The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
• Cells one chess knight or king move apart may not contain the same digit. (For example, r10c7 and r9c5/6 may not have the same digit.)
• Adjacent digits on a yellow/green/orange line must have a difference of at least 6/5/4.
• Any set of three consecutive cells along a red (entropic) line must contain a low digit (123), a medium digit (456), and a high digit (789).
• Any set of three consecutive cells along a dark teal (modular) line must contain one digit of each residue class modulo 3, i.e, the sets {147}, {258} and {369}.
• The 3x3 boxes split the blue line into connected components with the same sum.
• Digits joined by a black dot are in a 1:2 ratio, and digits joined by a white dot are consecutive. Not all possible dots are given.
• Digits joined by an X sum to 10. Not all possible pairs are given.
• Cells with a green circle contain an odd digit, and cells with a shaded square contain an even digit. Not all possible circles and squares are given.
