4.0 out of 5 stars
Good, but not killer puzzles, February 27, 2001
According to my performance in solving these puzzles, the answer to the question in the title is "pretty close." I was able to get many of them after only a few seconds, although admittedly some did stump me. The collection of 150 puzzles are original to the author, but the forms of most are in accordance with many time-honored formulas. Finding the next number in a sequence, starting with a word and changing a single letter at a time to transform it into another word are well-known methods of creating puzzles. Other classic problems are those involving letters placed in an unusual form in order to suggest a longer message and drawing the minimal number of lines so that all dots in a figure are on a line. The book is split into two sections, warm-ups and killers, with the latter advertised as being the hardest imaginable. That goal is not achieved. Granted, the killer puzzles are harder, but quite frankly some of them are almost obvious. For example, the message in
DAY DAY DAY DAY DAY CAST CAST CAST CAST
is not difficult to see. Another example is to find the general formula for the terms of the infinite sequence
3, 11, 19, 27, 35, 43, 51, 59, 67, . . .
Certainly not what I would envision as being examples of killer puzzles. No problem requires more than basic algebra and some require knowledge of different bases of enumeration. For some, simply thinking about them will do the trick. While I did enjoy reading and working through the puzzles, the level of difficulty appeared to me to be overstated. That is why I gave it four stars rather than five.
