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 always thought it was cool when someone could make a plausible estimate from reasonable guesses. I recently learned that these are sometimes named after Enrico Fermi, the famous physicist, and its the same technique used to create his famous Fermi paradox. You build a rough logic chain using a few sliders and fixed quantities (e.g. weeks per year), and the goal is to get within an order of magnitude of the true answer. The math is simple; the thinking is the game. Would love feedback.

I built a procedurally generated word-search game where the puzzle never ends - as you scroll, the grid expands infinitely and new words appear. It’s designed to be quick to pick up, satisfying to play, and a little addictive. The core game works without an account using the pre-defined games, but signing up allows you to generate games using any topic you can think of. I’d love feedback on gameplay, performance, and whether the endless format feels engaging over time. If you try it, I’d really appreciate any bug reports or suggestions. Thanks in advance!

Hey HN, My partner and I made a daily puzzle game called "bridj.link" (the dot is not silent). Thought I'd give Hello World in SolidJS a shot but ended up taking things a bit too far (to the point where we're now on our 99th puzzle!) Each puzzle has thousands of valid solutions. The tutorial goes into a bit more detail, but basically, each puzzle consists of a top word and a bottom word. These words need to be linked together using real words, made up of the tiles provided. In addition to an emoji summary of your solution, you'll get a fancy link that you can share with others upon…

Hello HN! We're Rory and Chris, and we've made a game called Dozenal[0], a grid-based number puzzle game where the objective is to use all the tiles on the board to create totals of 12 (hence the name). We think the mechanic is quite unique, although keen to hear if people know of similar games! You essentially drag tiles across the board, and the distance between two numbers decides the arithmetic operation when they connect to each other: zero spaces is addition, one space is subtraction, two spaces is multiplication: e.g. 5 → 4 = 9 5 → _ → 4 = 1 5 → _ → _ → 4 = 20 We've spent the past…

This is a little puzzle game I made based on Wolfram's rule 30[0]. I was doing some sketches based on old Genuary[1] prompts and for some reason this idea stuck with me, so I polished it up into a hopefully playable state. I wanted to keep things minimal, but as a semi-easter egg you can play custom variants using url parameters like https://demos.samgentle.com/wolfrominoes/?rows=20&rule=110 [0] https://mathworld.wolfram.com/Rule30.html [1] https://genuary2021.github.io/prompts
