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. In these sets, some sums are given as ? clues. ? clues are single digit clues, ?? clues are two-digit clues, and the leading ? cannot be a zero.
Deconstructed Sudoku: There are nine orthogonally connected sets of unshaded cells containing each digit from 1 to 9 exactly once, in the grid. Each unshaded cell is part of such a region and the regions may not touch orthogonally, but may touch diagonally.
Cipher: Clues are ciphered, where every distinct letter stands in for a unique digit 0-9. Every digit is assigned to a unique letter as well.

Puzzle Links: You can solve the puzzle in either Penpa+ or in the CTC software.
