Logic Masters Deutschland e.V.

Sudoku: Place digits from 1 to 9 in each cell of the grid such that no digit repeats in any row, column, or 3x3 box.

Numbered Rooms: Clues outside the grid indicate the digit which appears N cells in the indicated direction where N is the first digit in that direction. Outside the grid, digits have been replaced by letters. Same letters refer to same digits, and different letters refer to different digits. It is up to the solver to determine which letters correspond to which digits.

Arrows: Digits along arrows sum to the digit in the connected circle. Circles may only attach to one arrow, and arrows may never cross paths, or branch. Arrows always sum to a single digit number.

Fog of War: The grid is covered in fog. Placing correct digits will illuminate all cells immediately adjacent to that cell.
