The main complaint I saw for this product in reviews before purchasing is the material of the puzzles and I have to say I agree with past reviewers on this point. If you like to solve puzzles in pencil this is NOT the calendar for you... I like solving in pen so don't have that issue but have found that with some pens I've used the ink will smudge which can be annoying, it also makes the paper slightly see through so if you focus you can read the answer on the back of the puzzle - I'm the sort that would rather that not be possible since I can't unsee a number if I happen to accidentally see it while thinking, this hasn't happened to me yet but it almost did when I noticed it was possible and now just make an effort to not focus on it so it hasn't been an issue.The puzzles themselves are fun the solve and I love the variety of puzzle types as classic sudoku is not my favorite and it was hard to find a puzzle calendar that wasn't just classic sudoku or the mensa puzzle book I've purchased the last couple years - that I likely will go back to for next year but it was fun trying out a new one, so far the sum sudoku is my favorite of the sudoku variants. ### ⭐⭐⭐⭐⭐ great for pro sudokuers *by A***J on Reviewed in the United States on January 29, 2018* my husband does sudoku every day. so last year he got a regular sudoku calender and only the "evil" were interesting for him. so this year i got him this one and it is in abolute love with it. he raves about it every day, that they are perfectly challenging enough. a nice spin on advanced sudokuers! i got it also for my father in law. they are too hard for him to do and he got frustrated.looking for a level up for next year for my husband probably. if i can't find one, it will be this one again. ### ⭐⭐⭐⭐ Good games, but too small a layout. *by P***A on Reviewed in the United States on April 3, 2018* When I do hard sudokus, I like to write possible numbers in the squares. On this calendar, the boxes are a bit too small to do that easily. The page itself is large, but IMO, too much space is given to the calendar on the right. I would rather a much smaller (or not there at all) calendar and a bigger sudoku puzzle. The page itself is a good size. --- ## 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.co.uk/products/50855639-ultimate-sudoko-classic-irregular-multi-odd-even-diagonal-sum-2018](https://www.desertcart.co.uk/products/50855639-ultimate-sudoko-classic-irregular-multi-odd-even-diagonal-sum-2018) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
