Logic Masters Deutschland e.V.

Normal sudoku rules apply. Place the numbers 1-9 in each row, column, and box without repeating.

Sum Lines - Every segment of a given blue line has the same sum as every other segment of that line. A segment begins/ends when it crosses a black region border (including out of/into the puzzle). Different lines may contain different sums.

Numbered Rooms - Clues outside the grid indicate the digit which must be placed in the Nth cell from the clue, where N is the digit orthogonally adjacent to that clue within the grid.

OoB Lines - Lines that leave the grid must still follow the constraints of the line that they are on.
