Logic Masters Deutschland e.V.

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Copycat Cells: Place 9 Copycat Cells into the grid so that there is exactly one Copycat Cell in each row, column, and 3x3 box. Each Copycat Cell must contain a different digit. The value of a Copycat Cell is the digit in the cell rotationally opposite itself in the grid (180° rotation about the center of the grid). For example, if r2c3 is a Copycat Cell containing the digit 5, and r8c7 contains the digit 9, the value of r2c3 is the digit in r8c7, which is 9.
• Renban: Values along a pink line must form a set of non-repeating consecutive values in any order.
• Nabner: No two values along a yellow line can be consecutive or the same, regardless of their position on the line.
