Rule Hunter
Find the hidden rule. Solve the puzzle. Train your brain.
What it does
Rule Hunter is an inductive-reasoning puzzle game — no formulas to memorize, just patterns to discover. You're shown numbers linked by arrows or shapes and must infer the hidden rule to fill in what's missing. Five difficulty tiers (Easy→Master) each introduce a new way of thinking, across 8 visual formats: chains, hexagons, pyramids, spirals, symbol equations, and more. Free, ad-supported for hints, no in-app purchases. For fans of Sudoku, Wordle, or Math Riddles.

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:…

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
