As part of our low-tech gaming series, we present Quzzle. The Economist in a Dec 2^nd 2004 article entitled “A hard, simple problem“, portrays Quzzle, as “the world’s hardest simple sliding-block puzzle”. Quzzle was developed by Jim Lewis, an inventor based in NJ. Its objective is to move one of the large tiles from one corner to another.

Quzzle’s claim was shattered a couple of weeks later, when it was determined to require ‘only’ 84 moves, and quickly superceded by Gil Dogon’s 138 move puzzle which he calls Super-Century.
The objective of Super-Century is to move piece A to the lower middle of the board.
