This is a game I wish I had as a kid learning programming. The concept of it is fairly similar to other coding games like Screeps, but instead of a complex world with intricate mechanics, Yare is a lot more minimal and approachable with quick 1v1 <3 min matches. It's purely a passion project with no monetization aspirations. And it's open source: https://github.com/riesvile/yare The first version 'launched' several years ago and I got some good feedback here: https://news.ycombinator.com/item?id=27365961 that I iterated on.

The goal is to pick up clues from the surrounding code and fill in the missing lines as quickly as possible.

I had the idea when it dawned on me that reviewing and understanding code spat out by an LLM is a key skill for the AI era. (I sincerely hope you're critically reviewing what your favorite LLM is serving…

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…

I just started learning German, and it has been a frustrating experience, to say the least. There are so many seemingly arbitrary rules that make pattern recognition very difficult. Therefore, I have been looking for ways to make memorization a bit easier and fun. So, I came up with a bunch of games to make learning German a bit more engaging. Hope you find it useful as well!
