Puzzle No. 297 – 312 : Zeka 2013 Puzzle Set

I realize I’m crossing 300 with this without the usual special puzzle, but with Puzzle Marathon coming up, I’m sure everyone will have their fill of special puzzles. I’ll make it up later sometime between 300 and 400. Anyway, this was a 1 hour set at the Croatian competition. I basically started off with trying 1 classic puzzle and one variant of it, but then some pairings are just similar genres. For the variants, I’ll just put the additional rules. The Classic puzzles have links to their rules, and some are fully described here. The difficulties are obviously varied but barring the Pentomino I can’t immediately think of anything particularly difficult. All puzzles tested by Bram De Laat.

Enjoy!

P301 : Hashi (Probably the easiest puzzle of the set) – Draw single or double straight lines between the circled numbers. The number in a circle indicates how many lines must end there. The lines must run horizontally or vertically and must not cross or branch off. All circles must be connected to each other; i.e. it must be possible to travel from any circle to any other circle following the lines..

P308 : Cipher Nurikabe – The numbers are replaced by letters. All instances of the same letter have same values and different letters have different values. Note that the rule says values, so one letter can stand for a multi-digit number too.
