    I made this game for my children to play, as they are heavily into Wordle, and I thought they'd also like something maths based! Every puzzle is solvable and has at least one solution (usually more). There is a kids mode in the settings, plus a hard mode for extra difficulty.

  • Dozenal – A Game of Spatial ArithmeticJul 2026 · dozenal.game · ▲16

    Hello HN! We're Rory and Chris, and we've made a game called Dozenal[0], a grid-based number puzzle game where the objective is to use all the tiles on the board to create totals of 12 (hence the name). We think the mechanic is quite unique, although keen to hear if people know of similar games! You essentially drag tiles across the board, and the distance between two numbers decides the arithmetic operation when they connect to each other: zero spaces is addition, one space is subtraction, two spaces is multiplication: e.g. 5 → 4 = 9 5 → _ → 4 = 1 5 → _ → _ → 4 = 20 We've spent the past…

    Hi everyone, I built FuseCells, a minimalistic logic puzzle game where every level is handcrafted (no procedural generation). It started as a personal challenge to design a clean rule-set and scale it to thousands of puzzles without losing difficulty balance. What’s unique: • 2,500 handcrafted levels across multiple grid sizes • Deterministic logic — no guessing required • A rule system inspired by constraint-solving and path-finding concepts • Daily challenges and global progress tracking • Fully built as a solo dev project Technical notes for those curious: • Level generation tools I wrote…

    I built a free math-based puzzle game called Equatile2025 · equatile.com · ▲11

    Hi, I built Equatile, a logic-based puzzle game where you arrange number tiles on a grid to make every row and column equal their target values. It's built using Expo and is available for free on iOS, Android, and the Web. It's a game I've had in mind for almost 10 years now but never got to actually develop, until I came across Expo which made the process incredibly easy. I might open source the code on GitHub. I hope you enjoy playing it!

    BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

    I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
