Logic Masters Deutschland e.V.

The grid contains two complete Sudokus both independently following normal Sudoku rules. Fill in one Sudoku with the corner pencil numbers and the second with the centre pencil numbers. The same number may not appear from both grids in any cell.

Along the green line, neighbouring digits must be at least five apart - the green line applies only to the corner pencil digits. The grey line is a palindrome that reads the same in both directions and applies only to the central pencil digits.

Red cages indicate that the sum of the numbers from both grids in that square is ten (all red cages are given). The green cages indicate the sum is fifteen (all green cages are given). The blue cage indicates that the two digits add to five (not all blue cages are given).

To check once completed turn the central pencil digits into normal digits. No Sudokupad solution given.
