Logic Masters Deutschland e.V.

Sudoku: Normal Sudoku rules apply to both grids; place the digits 1-9 once in every row, column, and 3x3 box.

Ambiguous Lines: All lines are either Parity Lines or Polarity Lines. Each line is of one type in one grid, and the other type in the opposite grid. It is up to the solver to determine the nature of each line in the grid. Note: Different colors are used only to distinguish line intersections.

Parity Lines: Digits along a parity line alternate between odd and even.

Polarity Lines: Digits along a polarity line alternate between the sets {1,2,3,4} and {6,7,8,9}.

Killer Cages: Digits in a cage do not repeat and, if given, sum to the value indicated in the upper leftmost corner. If a value is not given, cages in the same position of each grid sum to the same value.

Expected Difficulty: 4 stars

This was set for Scojo's Setting Saturday Prompt, this week chosen by palpot: Invent/Make Something Crazy, in honor of the first prompt he participated in 1 year ago.

Inspired by Chistounet's Jumelage and Zodiac Project: Gemini. I highly recommend both!
