Products that do what Monty's Gauntlet – Do You *Really* Understand the Monty Hall Problem? does
A variant of the Monty Hall problem (the 7th one on this quiz) went semi-viral a couple months ago. For me at least, I may be able to walk through the reasoning of the original problem, and I may be able to convince myself it's correct, but it's very hard to build an intuition for why it's correct that feels truly sound. So I thought it'd be interesting to have a quiz to contort the original problem in as many ways as possible to challenge my understanding and intuition. Try it out!

I learned about the Monty Hall Problem recently. I thought it was so interesting it inspired me to make this small interactive website about it.

This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes)…

Hey there! I'm the brains behind the math crossword game on my site. This game is all about making math a little more fun – users just drag and drop numbers to fill in the blanks and move on to the next level if they get it right. Let me know if face any issues or have any suggestions! :)

I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

I've been playing with this for quite some time and I think it's finally ready for public consumption. All feedback welcome.

My dad makes the questions, I made the site. I think the genre and the level of difficulty is suited for HN. Hope you enjoy. (I promise no AI-generated questions, they are all hand made!).

Hey HN, About twenty years ago, while I was in college, I first stumbled upon James Propp's Self-Referential Aptitude Test [1] and absolutely loved it. Ever since then, I've had this idea of turning that concept into a daily game, and I've finally built it: https://www.logiquiz.com/ The game interface checks each question against the answers you've given, so it doesn't spoil anything by giving away the answers. There are five different tests each day, from very easy to very hard. I'd love to hear what you think! [1]: https://faculty.uml.edu/jpropp/srat-Q.txt

I decided I wanted to roll my own AB testing app for Django (https://github.com/crobertsbmw/RobertsAB) when I was finished, I came across this: http://stevehanov.ca/blog/index.php?id=132 Which is a very convincing article on why AB testing sucks and with a few extra lines, you can improve your algorithm to select the best test so you never go back and update your code (yeah right.) I then thought, how many tests does this thing have to run to truly figure out which is best? I made 4 tests with probability of success equalling 1/2, 1/4,…

Got tired of my debates with my friend's ending in "I'm right bc I said so" so I made a platform where you can debate with your friend's(or a bot, recently added feature) about whatever you want, and after the debate is done a LLM judges who's more sound in logic. Gain points and climb the leaderboard! Feedback and criticism would be appreciated(there's a discord in there if you wanna talk more in depth) p.s.: I decided to use google acc sign in since it makes the whole thing easier to manage(live chatroom feature, etc.). I don't actually do anything with your emails

I've been working on CurioQuest, a simple, clean trivia/fun facts game. It started as a little project for my friends and family and they've encouraged me to clean it up and make it public. I'd love to get feedback from actual web game enthusiasts before adding the next batch of categories and questions! This is not a commercial product; it's a labor of love that's still in development. It doesn't have all the planned categories yet, but there's reasonable content: little over 2600 questions, 7 categories, 4 levels of difficulty per category, 2 languages (English and Portuguese), PWA so…

Hi folks, I wrote a blog post about the two's complement. I always scratched my head about some details: - "Take the ones' complement and add one" - "Half of the range are negative numbers" - etc. Now I think I understand these details, but had to piece it together from some sources. I'd love to get your feedback on this post. Looking forward. BR, Pedram

I started an experimental series, "console.solve", on mini javascript challenges a few months back and received good feedbacks on it. So I created a [second one](https://colintoh.com/console-solve/issue-2?utm_source=colint...) this month. Not sure anyone here will be interested as it's not exactly pro-level stuff. But if you have an hour to spare, it can be a good distraction. For those who are interested, here was the [first challenge](https://colintoh.com/console-solve/issue-1?utm_source=colint...).

Hi HN! We were trying to have our team adopt AI more and had the idea for "AI Bingo" - hands-on, mini challenges that resulted in something delightful and real. Our team members were obsessed, they were saying it was "weirdly addictive." People made AI-generated ASMR videos, n8n automations, games. Our email marketer built an Electron app using Claude Code. We were stunned - people were learning by doing AND having fun. So, we've spent the last few weeks building Made That, where anyone can do the same challenges and see other people's submissions. A lot of people feel a lot of existential…

Hi Hacker News! My friend and I [1] would like to share with you something we did this week-end. We really like the idea of game jams like the Ludum Dare, and we’d like to participate, but it’s often complicated for us, as we are often limited by the rules inherent to this kind of competition: we have to be available at specific dates, and the rules doesn’t always work for us. For example: if you want to participate as a team in a Ludum Dare compo, you have 72h instead of 48h, and you are not required to publish your code. We realized that what we really like is: - To work together. - The…

I had an idea for this concept for a while and decided to build a little website around it. It's kind of a silly idea but I'm really curious to see how it plays out. If you're a particularly curious person, be warned. By submitting a payment to the game, you get to see how many other people were curious enough to play. You will be ranked based on your payment amount, and get to discover some interesting insights about the game's dynamics. Hope you like it

I wanted to learn more about RAG implementations, so I built something to solve the constant digging through manuals whenever we play a game. It's fairly simplistic, but actually has worked pretty well for some of these conflicts. Everythings Open Source on GitHub if you're curious (or have ideas), and I'd love to hear feedback from fellow boardgamers!

I’ve spent a year building a theory learning path that starts from scratch and goes all the way up to topics like Secondary Dominants and Borrowed Chords. It uses a combination of games, interactive lessons and spaced repetition to help you understand and remember concepts. Not just learn something new and forget it in a few days. I’m trying to figure out: 1. Is the progression logical? 2. What am I missing that you’d like to see in there? 3. Where does it get confusing and could use more clarification?

For the last couple of years I've created a Christmas quiz, which you can read about and play here: https://www.lloydatkinson.net/projects/2022/christmas-projec.... This year I created another quiz, this time general Christmas questions. Like last year the tech I used: - Astro - React - TypeScript - Framer Motion for the animation - A Netlify function that saves and loads the scoreboard from Azure Table Storage Unlike last year which was somewhat easy to cheat on by Googling, this time, the longer you take to answer a question the fewer points you get. I hope you…

I've been working on applying LLMs to long-context, verifiable problems over the past year, and today I'm releasing a benchmark of 62,000 pencil puzzles across 94 types (sudoku, nonori, slitherlink, etc.). The benchmark also allows for intermediate checks /rule breaks for all varieties at any step. I tested 51 models against a subset (300 puzzles) in two modes: single-shot (output the full solution) and agentic (iterate with verifier feedback). Some results: - Best model (GPT 5.2@xhigh) solves 56%. (~ half the puzzles are unsolved by any model) - Agentic solves average 29 turns. The…
