Test your shape rotation skills
Hi all, hope someone enjoys (or not) my weekend project. See how many matching pairs you can find in two minutes. This is written in C++ and built to WebAssembly with Emscripten. The code is at https://github.com/0xf00ff00f/rotator

In plain words
Test your shape rotation skills is a browser-based game where players find matching pairs of rotated shapes within a two-minute time limit. Built in C++ and compiled to WebAssembly using Emscripten, it challenges users to recognize geometric patterns despite rotation. The game is designed for anyone interested in a quick puzzle experience, with source code available on GitHub for developers interested in WebAssembly implementation techniques.

I made a pretty relaxing puzzle game2022 · rotaboxes.com · ▲633I had the concept in my head for some time and firstly just prototyped it using only HTML & CSS. Sent it to a few friends and they liked it so I made it into its own website and added few 'competitive' features like click counter and share button.
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…

Hello HN users, This is a CAD by code project I have been working on on my free time for more than year now. I built it with 3 goals in mind: - It should be familiar to CAD designers who have used other programs. Same workflow, same terminology. - Reduce the mental effort required to create models as much as possible. This is achieved by: - Provide live rendering and visual guidance as you type. - Allow the user to reference existing edges/faces on the scene instead of having to calculate everything. - Provide interactive mouse helpers for features that are hard to write by code: Only 3…
TetrisBench – Gemini Flash reaches 66% win rate on Tetris against OpusJan 2026 · tetrisbench.com · ▲111Hi HN, I built TetrisBench, a benchmark that tests LLMs on real-time code generation and reasoning through Tetris. Live: https://tetrisbench.com/ *How it works:* Each model starts with an initial optimization function for evaluating Tetris moves. As the game progresses, the model sees the current board state and updates its algorithm—adapting its strategy based on how the game is evolving. The model continuously refines its optimizer: - Board getting too high? Prioritize clearing lines. - Hole forming? Adjust penalties. - Safe stack? Build for a Tetris. The model generates…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
