Logic Masters Deutschland e.V.

• Normal Sudoku rules: Place the digits 1-9 in each row, column and 3x3 box, without repeats.
• Index Lines: The digit in the Nth cell along a green line (starting from the diamond) indicates the position along the line where the digit N appears. E.g. a 3 in the diamond puts a 1 in the 3rd position.
• Numbered Rooms: Digits placed on lines outside the grid indicate the digit which has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction. E.g. a 5 above column 3 and a 4 in r1c3 would place a 5 in r4c3.
