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)…

I made this game for my children to play, as they are heavily into Wordle, and I thought they'd also like something maths based! Every puzzle is solvable and has at least one solution (usually more). There is a kids mode in the settings, plus a hard mode for extra difficulty.

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…

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…
