Logic Masters Deutschland e.V.

Rules:

• Sudoku: Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
• Aqre: Shade some cells so that all shaded cells form one orthogonally connected area. There may not exist a run of more than three consecutive shaded or unshaded cells horizontally or vertically anywhere in the grid. The digit in the upper-left corner of each box indicates the number of shaded cells in that region.
• Japanese Sums: Clues outside the grid indicate the sums of connected groups of numbers in unshaded cells in the respective row or column, in order, where shaded cells serve as delimiters between groups.

  - '...' denotes an arbitrary number of Japanese sum clues. This could be zero, one, or multiple.

  - A question mark indicates any digit from 0 to 9, but no clue may have a leading zero.

  - '[X]' refers to a clue whose ones unit is X. For example, a [4] may refer to 4, 14, 24 and so on.

• Cipher: Clues outside the grid have been ciphered and each letter represents a different number from 0 to 9.
