Logic Masters Deutschland e.V.

The following rules apply:

• Irregular Sudoku: Each row column and irregular shaped region should contain the digits 1-7.
• Anti Factor Lines: Digits on a line of length n may not be any multiple or factor of n other than 1, and must sum to a multiple of n

N.B. Everything you see has been distorted by the shape of the mirror. All cells, line lengths and line sums should be treated as octal representations of their true value. e.g. A line that appears to be 14 cells long has a true length of 12 (i.e. 1x8 + 4). A line that appears to sum to 42 has a true sum of 34 (i.e. 4x8 + 2)
