Logic Masters Deutschland e.V.

Normal 6x6 sudoku rules apply.

From the perspective of a clue outside the grid, a digit in its row or column is:
• 'Seen' if it is larger than all other digits between itself and the clue;
• 'Hit' if it is the digit N in the Nth cell from the clue.

A "?" outside the grid indicates that the sum of all digits in that row/column that are Seen AND Hit is between 1 and 9 inclusive, and a "??" outside the grid indicates that this sum is 10 or higher.
