Although fairly inclusive were looking to replace The Million Word Dictionary which was not available.  Not nearly as complete and informational.

Bought this for my wife to replace a similar one she had literally worn out.  She loves it because she can find answers that she couldn't locate in similar crossword dictionaries I bought her.  If you like crossword puzzles, this is the dictionary to buy.  The only downside is it's a soft cover, so it deterioriates over time with use.

This unabridged version of "Webster's Third New International Dictionary" presents a landmark (American English) reference. It is an indispensable, all-inclusive tool, which would lighten the yokes of both writers and transcribers.
A rare single-volume monster, it harbours more terms and definitions than an average English speaker would ever need. Its contemporary outlook is solid: just as amazing as its price is reasonable.
Nevetheless, one sour-point of this gem is that its print-size is too small. Still, it remains a fine tool.

I enjoy the New York Times "Easy" crossword puzzles that are edited by Will Shortz so much, that I have spent time estimating when the next volume will be released. I just ordered volume 19. (The third or fourth volume that I have purchased.)  They are the perfect level for me. I find them challenging, but not too easy.  One day, I hope to progress to a higher level, but in the meantime, I'm having fun with these puzzles.

This is a GREAT crossword book. I've recently gotten into these, and this book is great. The level of difficulty is perfect - not quite as difficult as your classic NY Times puzzles (which are over my head, and I don't understand many of the references.) But they aren't super easy so that I fly through them and don't feel challenged. I'm a substitute teacher and have a lot of down time, and this book is my go to. I've probably put 25+ hours into this book so far, working on every puzzle, and I have yet to finish one. It's also a great quality book - it holds up well in my backpack and being thrown around a lot. The paper is nice and easy to write on. I would 100% repurchase from this brand/seller. The ONLY tiny tiny con of this book is that they repeat words with the same clue fairly often throughout the book in different puzzles.

This crossword puzzle book comes in a convenient size. The print isn't too small. It's great to pass the time instead of surfing the web!

This is exactly what I was looking for!  Although the title is "Light & Easy Crossword Puzzles", they ARE The New York Times crossword puzzles and edited by Will Shortz!  This means that they will still be challenging and that I know I will learn something from every puzzle.  I like that every category is covered from sports to classic literature (well, in my case I know nothing about sports, but I like the variety).  This is a fun book, and I highly recommend it.

This electronic dictionary has many good entries while some others are very short. The search capabilities are excellent. For example, you can search among the 190,000 definitions using combinations of search terms, which generates a list of all the entries that contain that combination in their definitions. Every word in the definitions, lists of synonyms, etc., are themselves hyperlinked to their own definitions.  This version (3.0) apparently will run on Windows 7 but not on Windows 8. But you can still load it onto a Windows 8 computer using a virtual machine to run a guest operating system (like VirtualBox, which is free and easy to use).

I like this crossword book because it is challenging without being impossible for my mental capacity.  I have purchased others that did not make sense to me or were too challenging or too easy.

The Penguin Concise Thesaurus is much better for crosswords as it has a very extensive list of synonyms for the word chosen.

This is a fun group game for trivia-lovers, crossword puzzlers, or lifelong learners. Super easy to explain and easy to bring all sorts of people in. Clues tend toward American history, but there is a nice mix of European and Asian history thrown in as well.

Indespensible games collection, but needs to be updated by better diagrams, algebraic notation and recent analysis.

This book presents us with a graded series of kakuro challenges.

The introduction is quite clear on strategy, although the Divide and Conquer section has a few paragraphs that hopefully will be corrected in later editions.  However, Chisolm looks only at the case where a single digit has been discovered.  As with Sudoku, a very useful tactic focuses on discovering pairs of cells that must choose from the same two candidates.  In Kakuro one may sum the two choices and subtract from the block total to give information about the other cells.  Similarly for three cells with three candidates, etc.

The challenges are presented in four levels of difficulty.  The first level problems are presented on an 8 by 8 grid, the longest blocks are of length 5.  The second level grids are 10 by 10.  The third level are on a 10 by 12 grid, with some blocks of length 6.  The fourth level are also on 10 by 12 grids, with a few length 7 blocks.

There are no length 8 or length 9 blocks.

It is possible to do the first level in ink, without having to record intermediate guesses.  The proper choices are pretty much locally determined by the situation in blocks not more than two or three cells away.  This is not true of later levels, in which some choices require resolution of situations at more distant cells.  A good pencil and eraser is essential.

I worked through all 201 puzzles and found the book to be effective in acquiring improved facility.
