Puzzle Competitions: ZeKa 2014

Last weekend was the ZeKa competition in Croatia. It featured both a individual and a team competition this year. The individual competition was won by Goran Vodopija; Marko Obradović and Dragan Tolomanoski finished second and third respectively . The team competition was won by Dragan Tolomanoski, Bojana Vojnović and Vanja Fornazar.
I provided one of the Team rounds this time. The theme of the round was Imposters. The round consisted of four classic puzzle types. Each type had 4 puzzles, where one of the puzzles was an Imposter. It wasn't actually solvable as that puzzle type, but was solvable under a different set of rules. The rules of this puzzle was provided. The imposters weren't designed to be logically deduced, but purely intended to break down under the original rules.
The four puzzle types were LITS, with Double Back as imposter; Shikaku, with Corral as imposter; Skyscrapers with Haido as imposter; Slitherlink, with Turning Fences as imposter. Two of these combinations have appeared on my blog as a Double Trouble puzzle. One of them appeared as such on Grant Fikes' blog. The other is probably possible as a Double Trouble puzzle, but haven't tried that yet.

Puzzles can be found below or in the following PDF.


Imposters Rules:

This test consists of four sets of four puzzles. Each set of puzzles consists of a certain type of puzzles. Except in each set there is an imposter. This puzzle looks like the puzzle type, but isn’t actually solvable that way. The puzzle has different rules, these rules are given with each puzzle type. The goal is to figure out which of the puzzles is the imposter and solve all puzzles under the correct rules.

Note: some of the original puzzles might also be solvable under the imposter rules. But the true imposter is the puzzle that is NOT solvable under the original rules.

  2. Great fun! Easier than most of the puzzles on this blog too, which isn't a bad thing.

    1. Thanks. They weren't meant to be hard. I tend to write harder puzzles for my blog as I enjoy writing such puzzles better as to test the logic in different genres. It helps me to understand the rules better and what is possibly with a given set of rules. When I'm able to write harder puzzles it means I get the logic of the genre well and will also be able to solve the puzzles.
      But for competitions I generally dial the difficulty down a bit so they're more time-friendly and solvable for beginners too.
