Products that do what Wirespan, a daily power grid optimization puzzle I made for my son does
This was a lot of fun to build! I have an autistic son who is extremely interested in power lines, electrical transmission towers, and how the grid works. I decided to build a little game for him. When I finally showed it to him with bated breath, he rolled his eyes and said, “Is it 3D? I’ll only like it if it’s 3D!” So, I decided to polish it up and release it to the world! You get a 9x9 map with one power plant, three houses, and terrain obstacles, and the goal is to connect the power plant to the houses with an optimal path. Beneath the coat of paint, it’s a graph theory optimization…

Hi HN, I am co-founder of Kickstage, a software company specializing in solutions for the electrical industry and lately grid operators. We are hiring engineers from different backgrounds, a lot of them software developers with limited experience in the sectors. Deep domain knowledge is key in our industry however, so we are constantly teaching the basics of power flow analysis, active vs reactive power, transmission line properties etc. With Jupyter notebooks and the Python console only, that's a tedious task and hardly ever led to a deep understanding of the topics. So we built BambooGrid:…

Long time listener, first time caller. I am coming up to the eight-month mark in my "Heads Down, Learn Programming" experiment. This is my first app, an open source Magic the Gathering sealed deck generator. At the moment it is severely limited in scope, but I've worked on it for ~ six hours and I figure this is a good time to stop and let it breathe for a while. It's on github (https://github.com/alxjrvs/Sealed-Deck-Generator), as are a number of other half-completed project. Each was started with a goal in mind ("Mess around with Bootstrap", "Get off your ass and TDD", "Kick around complex…

Hi everyone, I built FuseCells, a minimalistic logic puzzle game where every level is handcrafted (no procedural generation). It started as a personal challenge: design a clean rule-set and scale it to thousands of puzzles without losing difficulty balance. What’s unique: - 2,500 handcrafted levels across multiple grid sizes - Deterministic logic, no guessing required - A rule system inspired by constraint-solving and path-finding concepts - Daily Challenge + leaderboards (I added these to give the game a “reason to come back” without turning it into a grind) - Built end-to-end as a solo dev…

Thirteen years ago, I had an idea: build a bomb from different stages and materials, call in an airdrop over a zombie-infested city, and let physics do the rest. Set off chain reactions through fuel stations and car wrecks. The catch? There are survivors down there too, so every strike is a balancing act. I’ve always loved messing around with physics demos, and in my head, the core loop was already fun. So I built a few prototypes, but none of them stuck. I never clicked with Unity, and every attempt eventually died. Every couple of years, I’d check the App Store, Steam, or just search…

This is a tetris style game where you need to fill 5×8 grid completely with 10 falling blocks. Simple game based on skill and logic. Feedback is much appreciated.

Hi HN, I'd like to share a logic number puzzle game I created! It is somewhat reminiscent of Sudoku and Minesweeper, but with its own twist. The rules are simple but it can be quite challenging! Please enjoy :) The feedback on the game prototype was invaluable and I incorporated a lot into what I hope is a more polished version of the game. What's new: Introduced a daily puzzle challenge. Dark mode. Enhanced user experience with improved UI. I'd love to hear your thoughts on these updates. Feedback is always appreciated!

I built a daily puzzle where a piece of paper is folded and hole-punched, and you predict where all the holes end up when it's unfolded. It's the kind of thing I used to do in grade school with actual paper and scissors, and it turns out the mental version is a surprisingly good spatial reasoning challenge. Three difficulties each day: easy is a 4×4 grid with one fold, hard is 6×6 with three folds. It's built with Next.js. The puzzles are generated deterministically on the fly using a daily seed. The engine runs a forward simulation of the paper folds using 2D coordinate mirroring, then…

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…

Hello HackerNews, I'm Kaamkiya, the author of this program. It's a collection of minimal games made for terminals, like 2048, Hangman, and even two player games like pong. They're all text-based, but they can actually be quite fun. If you want to test it right now, you can do this: go run github.com/Kaamkiya/gg@latest I started this project out of boredom, honestly. I was bored, and when I'm bored I like to code or play video games. So I coded video games. I kept them really minimal though, because I'm not great at gamedev and thought it would be easier to contribute to text-based…

Built this with my roommate over the weekend. At the end of the game, GPT will share its reasoning for each choice, which yields some funny results and explains why its so hard to win. Enjoy!

A few weeks ago, I got into the rabbit hole of creating neatly wired breadboards. I got sick of spaghetti wiring and unstable connections when I wired an esp32 based lora node and carried it around the block for reception tests. I thought of using pre-cut jumper kits laying around and planning the wiring ahead of time so I could have neater wiring. I also wanted to share the wiring with fellow hardware hacking enthusiasts in my local hackerspace. First I tried a square-grid paper, then moved to Figma and after not too long I remembered we can create web apps quickly in the age of AI. And…

This dashboard is a personal project I've developed to visualize every wind farm's energy production across Ireland. I'm trying to break into software development/data analytics sector and I wanted to build a project to practice my coding. I wanted to build a novel project rather than following along to a basic YouTube video project and not really learn anything. I'm interested in the renewable energy sector and after browsing the web noticed there isn't any public data on real time wind energy production in Ireland. I took the task onto myself to attempt to build a dashboard that…

In each level, the goal is to climb to the top of the wall. Each wall has a unique layout of handholds, magnets, hooks, and elevators, and only one path to the top. The challenge is finding the right combination of moves to get you there. After each unsuccessful attempt, you can view the entire wall from afar to plan your route and strategize before trying again. I just released this on App Lab and would love to get some feedback and see how much interest there is in the concept. It’s listed at $3, but if anyone here wants a free key, just email me at [email protected]. I also set up…

We wanted to test if a smaller model like GPT-4.1-mini could beat its bigger brother 4.1 at the game Tic-Tac-Toe using only context engineering. We put them in a 100-game tournament. For the smaller model, we gave it a few examples of winning moves from past games right before it made its own move. The results were clear. Without the examples, the smaller model struggled against GPT-4.1. With the examples, its effectiveness increased by nearly 200%, and it consistently won. It's a simple demonstration, but it shows that a smaller, faster model with good, timely examples can outperform a more…

Me and my boyfriend are making a puzzle game together. The goal of the game is to follow a specific pattern by moving around in a grid. Since we are both web developers, we chose to do it in React and Typescript rather than a game engine. We will release it on Steam in November, using Electron to package the app as a desktop executable. Not sure if it has saved us time to do it in React, but we didn't feel like learning a new tool and it has worked really well! I thought making a game would take a lot of time, but we started in December so we will finish this project in less than a year. And…
