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)…

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…

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…

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! :)

Hi HN, I was inspired by Wordle to make Colorfle, a different take on the genre where the goal is to mix colors together to match the target color within six tries. There were some interesting problems to tackle in making this game, one of them being the difference between mixing digital colors and real-life behavior (in RGB, blue + yellow = grey!). I hope you enjoy it -- any feedback would be much appreciated!

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

The idea for this pixel art puzzle game came from playing Triominos, and wondering what would happen if you replaced numbers with colors. A few mutations later, and it became a mobile game where you click a piece to turn it in place, to recreate pixel art. I built the basic idea in just over an hour on Twitch. Dev-wise, I used a homebrew Typescript game engine I created, called Booyah (https://github.com/play-curious/booyah). The graphics are all rendered using the awesome library PixiJS. What do you think?

Hi, I built Equatile, a logic-based puzzle game where you arrange number tiles on a grid to make every row and column equal their target values. It's built using Expo and is available for free on iOS, Android, and the Web. It's a game I've had in mind for almost 10 years now but never got to actually develop, until I came across Expo which made the process incredibly easy. I might open source the code on GitHub. I hope you enjoy playing it!

While on paternal leave, I wanted to create a game my newborn daughter could eventually play and learn something from. I was heavily inspired by the daily puzzle games I consistently play such as Wordle and Strands. Refractor is a game about connecting colored tiles together to reach all the goals. Use "refractor" tiles to combine two colors together but be careful not to trap yourself in! The game is won when all goals are fulfilled. The tech stack is: Laravel + Inertia, React + TypeScript, and DaisyUI + TailwindCSS. Open to any questions or feedback. Hope you might find it interesting!
