A series of actually hard puzzle books, so far sudoku, killer sudoku and some fiendish wordsearches that only use 5 letters per grid.

A sample wordsearch is available as a pdf here: https://extremepuzzlebooks.com/assets/sample/extreme-wordsea...

I'm quite proud of this wordsearch concept as I've not seen it done before.

All the logic puzzles have an online solution to show step by step how you can complete them.

I've been working on the software to generate, test and verify these for a couple of years and finally built up enough puzzle stock that meets the difficulty requirements to properly launch.

Now the work is on every hackers favourite part... Marketing!

Neat!

Somewhat related, I built a browser-based version of my favourite deduction game: https://github.com/kristiandupont/sherlock

Not everyone's cup 'o tea, but there's a letter search puzzles too:

Haha, I really love the word search. All my usual tactics fall apart - the limitation on the letters is adversarial in an oddly satisfying way. Cool idea.

Thanks, yeah I like the way it's effectively a kids game, but made very hard by one simple change.

Placing the words/extra letters in a way that you don't accidentally make duplicates was a challenge involving a _lot_ of tree walking.

reply


Oh interesting, I hadn't considered that, but of course that would be quite the challenge haha, with relatively short words like you picked

reply


oooh if you ever do logic grid puzzles I am so there

I have several more puzzles in the works, is there a particular type of one you're interested in?

With game dev, especially live ones with an active player base you do _not_ want to break things if you're a small studio.

But moving fast and shipping features quickly is a killer trait those small teams can use to be better than the big studios. (who ironically seem to ship slow and still break things)

Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. If they'd cover it on TV news, it's probably off-topic.


Really difficult puzzle books that will only be available in dead tree format. Extreme killer sudoku, very hard wordsearches etc.

Was hoping to have these ready for Christmas season, but life as always gets in the way!


Magic links are so useful in specific circumstances. We have a client with hundreds of users that infrequently need access to a bespoke tool. Setting up and managing user accounts for them is out of the question, but a magic link letting them sign in using an email of their corporate domain solves the issue easily.


That brings back memories. I entered a 2d duckhunt game in JavaScript, lots of nice comments, but no judges recognition.


No this nitpicking is people wanting to know the specs of something they might buy. What most people on HN probably think of as e-paper is not the same as and LCD tech.


Part of the problem is there's some use of e-paper to mean "e-ink but we don't want to trigger their trademark lawyers" polluting the space. (The part of the description that actually made sense to me was where it said "same display tech as in Pebble!" ... which is pretty neat, and not-at-all-eink...)


You forgot the /s right? Most of the world doesn't have that kind of connection.


I don't see how this is a huge problem. You don't need to download the executable once per minute.


Yes, some of us have faster internet. (Assuming freilanzer talked about megabits, not megabytes.)


I can assure you 99% of my data/files never see the cloud other than as encrypted containers for backup. That's good practice for most business is it not?


What do you have to hide? This makes us very suspicious. /s


I know you're /s but it's not even about privacy, it's the cost of mitigation after $cloud_service_x has a data breach and we then have to assign resources to account for _our_ clients data etc.


this is a terrible argument. Would you enjoy going to the toilet when a certain group of people (like your neighbours) could watch you doing your "business"?


Perhaps you missed the /s or didn't know it means "I am being sarcastic." A terrible argument made sarcastically is a good argument.


thanks for the clarification


-> /s


I can assure you that 99% of people and businesses do not operate that way, and that people you communicate with, buy from, and sell to, are all sending your data effectively unencrypted to the cloud.


Gdpr means data out of my control is someone else's liability. If they want to play fast and loose, that's their look out.


Looks very nice - I see there is the ability to edit metadata, but I often have a need to strip/delete _all_ meta data from a document. Having that as a single option would be very useful...


Thanks, that shouldn't be too hard to add. I have noted it down and will have a look at it.
