Japanese loop

(Published on 27. June 2012, 13:39 by Fred76)

  • Draw a single closed loop along the gridlines. The loop does not touch or cross itself. Write a digit from 1-9 (1-5 in the example) in each cell of the diagramm.
  • The loop passing through rows and columns separates the digits into several blocks. A block may be just one single digit.
  • The numbers beside and above the grid indicate, in the correct order, the sums of digits of each block, in the respective row or column.
  • No digit may appear more than once in each row or column.

Example:

Puzzle:

Solution code: Digits of the main diagonals. First from top left to bottom right, then from bottom left to top right.

Just added a clarification: The loop does not touch or cross itself. (writing rules is not the fun part of the job...)
