24 alternatives to Wirespan, a daily power grid optimization puzzle I made for my son

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…

Wirespan is a daily puzzle game where players route power from a plant to houses on a 9x9 grid using the least wire possible. The game combines graph theory optimization with the challenge of balancing square-based… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…

    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)…

    Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing…

    This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

    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…

    Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

    "Lights Out" is a mathematical puzzle that lives on an grid where each cell of the grid is one of two colors: either red or white. The goal is to eventually get all the cells in the grid to be red. What's the catch? Clicking a cell will not only flip its color, but also that of all cells sharing the same row or column as it. To me, this game feels like playing with a Rubik's cube --- every time you think you are fixing one cell, you mess up its neighbors! There are many ways to arrive at a solution... some mathematical (linear algebra, or combinatorics), others more logical,... and yet…

    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:…

    Building a 1D-Pong game is a bit of a rite of passage at the Chaos Communication Congress. I was inspired by a version I saw at 38C3 and built my own interpretation for 39C3. Lots of people enjoyed playing it and even Elliot Williams featured it in his 39C3 Hackaday Podcast. And I can attest: it's truly fun because it's sooo simple at first sight - but wait until the speed increases... Not a bad work to fun created ratio for such a little project. I used the opportunity to play around with Claude Code on my preexisting codebase to publish a nice-ish repo on GitHub. It worked great without…
