Bisecto – A minimalist game about cutting shapes into 50/50 halves
Hey HN, I built Bisecto (https://bisecto.com), a minimalist browser game with one simple mechanic, cutting (bisecting) a procedural 2D shape into two exact 50/50 halves with a single straight line. Confession: I got completely hooked watching those viral reels of people trying to cut fruits and vegetables into perfectly equal halves, and that was my inspiration for this game :D I've been writing code for 12+ years, but for this project I leaned heavily on LLMs to quickly spin up this game, I thought it's going to be quick, but it took me some time (around 2 weeks) to make the…
What it does
Bisect geometric shapes into exact 50/50 halves. Can you hit 100% precision? Play the daily challenge, arcade mode, and friend challenges.
Keep every cut at 95% or better. Miss the target three times and your run isfrom bisecto.com
In the maker’s words, at launch
Hey HN, I built Bisecto (https://bisecto.com), a minimalist browser game with one simple mechanic, cutting (bisecting) a procedural 2D shape into two exact 50/50 halves with a single straight line. Confession: I got completely hooked watching those viral reels of people trying to cut fruits and vegetables into perfectly equal halves, and that was my inspiration for this game :D I've been writing code for 12+ years, but for this project I leaned heavily on LLMs to quickly spin up this game, I thought it's going to be quick, but it took me some time (around 2 weeks) to make the game the way I want it to be. A few game modes to try: - Classic: Endless run, you get to choose difficulty and line cutting mode - Arcade mode: You get 3 lives, you have to keep accuracy above 95%. - Daily challenge: A shared daily seed, 10 identical shapes for everyone, see how you rank. - Friends challenges: Create a challenge and send it to your friends and see who is better at cutting shapes in half. Under the hood: - Runs 100% client-side with pure TypeScript and HTML5 Canvas 2D. No framework or build bloat. - Procedural polygon generation (with concave traps and inner cut-through holes on higher difficulties). - Slicing uses Sutherland-Hodgman polygon clipping against an infinite line plane, and areas are calculated on the fly using the Shoelace formula. - No ads, tracking cookies, account signups needed only to create a challenge, email is optional and needed for password recovery only. Give it a spin on desktop or mobile. I'd love your thoughts on the gameplay, UI feel, controls, or any ideas to make the game better and more addictive (if that's even possible :D)

hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

Hey everyone, I'm Fabio, a very long time lurker here. Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago. I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)! What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :) I'd…

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!
- CACoderoulette, a pair programming game for developers2016 · ▲42
Hello everyone, We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers. We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference. You can check it out here: https://www.coderoulette.com/ We also published an article explaining how we built it. I'd love to hear your feedback.…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
