This pdf is 13 pages long, 1 page front cover, 1 page advertisement, 2 pages editorial, 1 page ToC/foreword, 1 page SRD and 1 page back cover, leaving us with 6 pages of content, so let's check this out!
The pdf kicks off with an introduction on word-play and language-dependant riddles as well as advice on designing riddles yourself. We also get a whole page on how to best use riddles and how to place them. After that, we get 41 different wordplay riddles. To give you an example:
"Until I am measured, I am not known, yet how you miss me when I have flown."
We also get 32 descriptive riddles - which also thankfully omit tried and boring "mouth-river" and 4-2-3-leg-classics. An example would be:
"A box without hinges, key or lid yet golden treasure inside is hid."
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to RSP's 2-column standard in elegant b/w, comes with two versions (one for the printer and one for screen-use) and the pdfs are extensively bookmarked.
This pdf actually proved to be rather interesting for me: I expected to know most riddles herein and was positively surprised when I didn't know all of these riddles. While I did know some (or at least variations of them), most of the riddles not only are thankfully rather innovative and also thankfully lack real world mythology/nods. If you're a riddle-buff or very good at solving riddles, you probably don't need this, but if you're not and look for some, this is a neat offering of nice, though not too hard riddles.
All in all, I enjoyed this collection of riddles by Liz Smith, though I would have liked to see one page of content more, perhaps devoted to puzzles or mathematical riddles. In the end, we get a nice selection of riddles for a low price and thus, I feel justified in rating this pdf at 4.5 stars and round it up to 5 stars.
[5 of 5 Stars!]
