SineRider, a math puzzle game
Messing with your TI-84 graphing calculator is a rite of passage for every teenager who has ever been bored in a math class. In 2013 I was that teenager, and it gave me an idea for a tiny game about sledding on graphs. This project grew into my white whale, and I spent my twenties trying and failing to finish it alone. I shelved the game when I started working for Hack Club in 2018—until last May, when a few community members took it off the shelf. The project took on a life of its own, and turned into a year of nights and weekends from a global team of 20+ teens in 8+ countries. Today…

SineRider - A game about love, math, and graphing built by teenagers2022 · sinerider.com · ▲220Hello everyone! It was so fun working on this project for the past few months with some of my fellow high school students :) I am so excited to share our first prototype and hopefully we'll be done with it all soon! <3 (ofc, it's open source, contribute here: https://github.com/hackclub/sinerider) The goal of the game is to slowly teach function composition that get progressively more complex while you also help the ghosts ski on the slopes and explore the entire map!
- IMI made a puzzle game that gently introduces my favorite math mysteries2024 · rahulilango.com · ▲1,054
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 a web game that makes practicing basic arithmetic fun2024 · worchle.com · ▲161Hey, 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…
