Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply.

Index Lines: On an index line, the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears. Eg: 32154 would be a valid line; the 1st digit, 3, indicates that the 3rd cell contains a 1, the 2nd cell a 2, and so on.

Numbered Rooms: All outside cells on a line must contain a digit. That digit must also appear in the Nth position of that row/column, where N is the digit in the first cell of that row/column.

All feedback (positive or critical) appreciated!
