Reconstruct masterpieces in a circular puzzle game
What it does
Famous artworks sliced into concentric rings and wedge-shaped pieces. Slide them along arcs, swap them between rings, and reconstruct the masterpiece. No grid. No jigsaw. A circular mechanic you won't find in any other puzzle game. 45+ public domain paintings — from a 3,350-year-old Egyptian fresco to Van Gogh, Vermeer, Klimt, and Hokusai. Each includes artist info and museum details. Progressive difficulty, timed challenges, satisfying snap animations, and offline play.

I 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.

- IWI wrote a symmetry game with a daily puzzle2024 · hidden-mirrors.com · ▲126
I’ve been working on a puzzle game for a few years as a side project. The game is based on a small region of tiles in a grid that is mirrored, modified, and mirrored again. It’s based on a novel phenomenon I noticed where, once these mutations happen a few times, the original region can be hard to recognize. You have a feeling there are symmetries in the image, but they are just out of grasp. Going further, if only part of the region is visible, such as mirroring off the edge of the board, it adds to the feeling and it becomes a satisfying puzzle to solve. I originally published this on the…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
