Information Density: Mr Puzzle – Signal Evidence & AI Readability

Mr Puzzle

Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.
29 Impact Weight: 30 / 100

Information density is exceptionally high with almost zero fluff. Headings such as Brian’s Big Baffling Bolt (aka BBBB) and LetterBox IPP42 Exchange Puzzle lead into body text containing specific production numbers (105 made, 340 made), material specifications (3mm clear acrylic), and exact historical pricing (AU$50.00). The ratio of substance to marketing language is nearly 1:1, a rarity in ecommerce.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

📝 The Narrative — clean text per page (the substance-vs-filler signal)

[IMG: About Us]

[H1] Who is Mr Puzzle?

[H2] About Us

[H2] At Mr Puzzle we know puzzles!

[H1] BIG NEWS!
[H4]
Brian and Sue have now retired. Our last day of trading on this website was 21st December 2023.
[H4] If you need to contact us we can still be reached via the Contact Us page or email directly to [email protected]
[H4] For a little while from February 2024 some of the last of our stock will be available at the Mr Puzzle eBay shop. https://www.ebay.com.au/str/mrpuzzleshop?_trksid=p4429486.m3561.l2563 Check it out. Still some great puzzles to be had.
[H4] We extend a HUGE thank you to all our fantastic customers who’ve kept us in business all these years since 1998 on the web and since 1992 at the markets before that.
We hope we’ve provided you all with lots of perplexing puzzling over the years!
[H4] Keep on Puzzling
Sue & Brian

[H2] We sell ONLY puzzles.
[H3] We’ve been making and selling complex puzzles and brainteasers since 1992 and had an online store since 1998. There wasn’t even any google in those days!
[H3] **This store closed in December of 2023 when Brian and Sue officially retired.**

[H4] Our specialty was very hard puzzles and other specialty puzzles sourced from around the world; many of the puzzles we sold were not available anywhere else. Wood and metal puzzles from specialist puzzle makers and designers. All types of mechanical puzzles. Sequential discovery puzzles, interlocking burr puzzles, cast metal puzzles, wire puzzles, sliding block puzzles, tangram, soma, nail and rope disentanglement and all your other old favourites too.

[H3] So, who is Mr Puzzle himself?
Brian Young has been making puzzles at Mr Puzzle since 1992.  Mr Puzzle started out selling only our own brand of puzzles way before internet shopping was thought of. We sold our puzzles at a craft market at Southbank Parklands in Brisbane. From 1998 when we launched our first website we knew it was going to be a great way to connect to many international customers who were visiting Australia and found us at Southbank and wanted to buy more puzzles. Over the years we started combining selling our own product with puzzles bought in from other suppliers; most of whom do not sell via any other outlet in Australia.
Brian himself is well known to collectors around the world for his amazing Limited Edition puzzles, very hard burr puzzles, and more recently his sequential discovery puzzles.  His last Limited Edition SMS Box (series now Sold Out) is generally acknowledged as his hardest puzzle ever and there are many collectors out there who’ve never been able to solve it.
Brian is also a puzzle collector and puzzle solver. He enjoys playing with puzzles and sourcing puzzle designs.
As Mr Puzzle has grown Sue Young has taken over the Administration. We’re a small team but that just makes our service more personalised.
