Vom 1.3.2012 bis zum 13.3.2012 veranstaltet der serbische Rätselverein wieder einen Optimier-Rätselwettbewerb:
Choose the starting field and write number 1 in it, and then complete the net with the numbers from 1 to ‘n’ moving only across or down. If you are on the odd number you have to change position to the first field next to it (left, right, up or down), and if you are on the even number you have to ‘jump’ 2 fields in one of four possible directions. Inside the visited fields you need to write numbers 1,2,3,4,5… to ‘n’ in that order, and each of the fields can be visited only once, It is not allowed to jump in side the black fields, but you can skip over them.
