ABSTRACT

Rightly so or not, the puzzle inventor is often perceived as a fi endish sort whose only purpose is to confuse and frustrate others. Witness the names frequently given to the instruments of the profession: Devils Dice, Instant Insanity, Diabolical Cube, and so on. Anyone who has ever sold puzzles over the counter at craft shows has been asked many times for a puzzle that will drive someone else crazy (usually a close relative!). In this book, we have tried for the most part to present the other side of the coin-geometric recreations that are fascinating and often challenging, but where confusion is not the ultimate object and deception is not the means to that end. The Pennyhedron puzzle just described in the previous chapter, especially the confusing pair, bears witness to good intentions gone astray. In this chapter are two more inventions in the same deviant vein.
