Logic Masters Deutschland e.V.

Rules:

• Normal Sudoku rules apply.
• Digits along lines sum to at most 2 different totals, to be determined by the solver.
• Modular lines : every set of three sequential digits along a teal line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line, if allowed by other rules.
• Modular squares : every 2x2 square must contain at least one of each set of residues modulo 3.
• Digits joined by a black dot are in the 1:2 ratio. Digits joined by a white dot are consecutives. Not all dots are given.
