Logic Masters Deutschland e.V.

Rules

• Normal Sudoku Rules Apply: Place the digits 1 to 9 in every row, column, and box, without repetition.
• Bulbless Thermo-renbans: Digits along a grey bulbless thermo-renban line form a non-repeating consecutive set of digits which strictly increase from the bulb end. Each line has exactly one bulb at one end, but which end must be determined by the solver.
• Diagonal Sums: A number with an arrow outside the grid indicates the sum of the digits pointed to along the indicated diagonal. Digits are allowed to repeat along those diagonals as normally allowed by the other rules.
• X-Sums: A number without an arrow outside the grid indicates the sum of the first N digits, where N is the digit in the closest cell to the clue. A parity outside the grid indicates the parity of the sum of the first N digits, where N is the digit in the closest cell to the clue.
