Logic Masters Deutschland e.V.

I missed several weeks of Scojo's Setting Saturdays, so I decided to combine the prompts for 2 weeks. One of which was Tentropy Lines and Anti-Queen, and the other was Anti-Quads and Zipper Lines.

Solve in SudokuPad

Sudoku: Place the digits 1-9 once each in every row, column and 3x3 box.

Anti-Quad: Each purple circle has a value which is a one-digit or two-digit number. These digits may not appear in any of the four cells touched by the circle.

Anti-Queen: Any digit in any purple circle value may not appear in a cell in the grid which sees another of the same digit by a chess queen's move, i.e. diagonally or orthogonally.

Zipper Lines: Along purple lines, all pairs of digits in cells an equal distance from the centre of the line have the same sum. This sum is also equal to the purple circle value in the middle of the line.

Tentropy Lines: Along purple lines, no run of 4 adjacent cells may contain digits from the same 'ten group'. The 'ten groups' are the pairs of sudoku digits which sum to 10 (i.e. [1,9] [2,8] [3,7] [4,6]). The digit 5 may never appear on the line.
