Logic Masters Deutschland e.V.

Rules:
Liar Japanese Sums: Shade some cells in the grid such that clues outside the grid indicate the sums of the continuous blocks of unshaded cells in that row or column. Place digits from 1-9 in every unshaded cell such that no digit repeats in a row or column. At least one shaded cell must separate the blocks. For every clued row or column, 2 different sets are provided (Left / Right for rows, Top / Bottom for columns.) One set is correct, with correct sums in the correct order.(Always left to right or top to bottom.) The other set is a lie (As a whole, individual parts of the liar set can still be sometimes correct). Which sets are correct must be determined by the solver.
Cave: The filled (unshaded) cells of the Japanese Sums puzzle form a cave: all filled (unshaded) cells are orthogonally connected and every empty (shaded) cell is orthogonally connected to the edge through a set of shaded cells.
Aqre: There may not exist a run of four or more consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid.
