Corral – A Visual Logic Puzzle About Enclosing Numbers
Hey HN! I just finished building a puzzle game called Corral, and I’d love to share it with you. It’s a logic puzzle played on a rectangular grid, where some of the cells contain numbers. Your goal is to mark which cells are inside a single continuous loop that encloses all the numbers. For each numbered cell, the number tells you how many cells are visible in the four orthogonal directions (up, down, left, right) until a wall of the loop is hit, plus the cell itself. So a cell with a 2 must see one empty cell before hitting the loop boundary. Gameplay is all about deduction: you can mark…
In plain words
Corral is a logic puzzle game played on a rectangular grid where players mark cells to form a single continuous loop that encloses all numbered cells. Each number indicates how many cells are visible in four orthogonal directions before hitting the loop boundary, including itself. Players deduce which cells are inside or outside the loop, with the constraint that the loop must be one unbroken shape with no isolated regions inside. It's designed for puzzle enthusiasts and offers three difficulty levels, with every puzzle solvable through pure logic.

Hey HN! I just finished building a puzzle game called Corral, and I’d love to share it with you. It’s a logic puzzle played on a rectangular grid, where some of the cells contain numbers.

For each numbered cell, the number tells you how many cells are visible in the four orthogonal directions (up, down, left, right) until a wall of the loop is hit, plus the cell itself. So a cell with a 2 must see one empty cell before hitting the loop boundary. Gameplay is all about deduction: you can mark cells as definitely inside or definitely outside the loop. The loop must be one continuous shape, with no "islands" inside. Every puzzle has a solution and can be solved using pure logic. There are three difficulty levels that you can choose from, enjoy! Would love to hear your thoughts, ideas, or bug reports. Thanks for taking a look!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
