Colossal Grab A Pencil Book of Logic Problems Review: One of the best logic puzzle books I have found - I have purchased many logic puzzle collections and this one, as well as the mammoth puzzle collection, are hands down the best. Pros: The puzzles are quite challenging overall, but there are varying difficulty levels The puzzles are creative. They are not all solved the same way, some have extra variables, and you can tell these were written by a person and not a computer (looking at you, puzzle baron). The puzzles are diverse and unique. Cons: No answer table. I know some people use these to solve the puzzle and some just like to have the answers down to compare to the answer key. I don’t mind its absence. I love these books and wish there were more! Review: Looks great, Best part is that the answers are not ... - Arrived on 1/8/18, earlier than I expected. Looks great, Best part is that the answers are not just listed, but contain the reasons for each answer line by line. That is something I love. I look forward to working this book. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #3,717,949 in Books ( See Top 100 in Books ) #8,272 in Logic & Brain Teasers (Books) #17,806 in Puzzles (Books) | | Customer Reviews | 4.2 4.2 out of 5 stars (52) | | Dimensions | 7.5 x 0.9 x 9.24 inches | | ISBN-10 | 0884865886 | | ISBN-13 | 978-0884865889 | | Item Weight | 1.65 pounds | | Language | English | | Print length | 416 pages | | Publication date | October 7, 2015 | | Publisher | Bristol Park Books | ## Images ![Colossal Grab A Pencil Book of Logic Problems - Image 1](https://m.media-amazon.com/images/I/81gE+NXyEsL.jpg) ![Colossal Grab A Pencil Book of Logic Problems - Image 2](https://m.media-amazon.com/images/I/418ZXFEye+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ One of the best logic puzzle books I have found *by R***E on June 2, 2018* I have purchased many logic puzzle collections and this one, as well as the mammoth puzzle collection, are hands down the best.

Looks great, Best part is that the answers are not just listed, but contain the reasons for each answer line by line. That is something I love. I look forward to working this book. ### ⭐⭐⭐⭐ Exactly what I wanted *by K***S on January 4, 2016* It's all grid logic puzzles! Pretty nice paper. The two downsides are: The puzzles don't have the "fill in the answer table", which I use for harder puzzles to figure them out. The first 50 or so puzzles are SUPER easy. But the puzzles do get SIGNIFICANTLY harder, so I use the easy puzzles as like a break from the extremely hard ones. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/33622295-colossal-grab-a-pencil-book-of-logic-problems](https://www.desertcart.com.br/products/33622295-colossal-grab-a-pencil-book-of-logic-problems) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-04-25*
