Hey Product Hunt! 👋 I'm the solo developer behind Minesweeper 3D – built from scratch in Three.js as a hobby project, nights and weekends. Classic Minesweeper, but every cube has **up to 26 neighbors** instead of 8. The geometry alone breaks your brain in the best way. What makes it different: 🧠 **Logic Solver** – built-in autopilot that explains every move with speech bubbles ("Number 3, 3 unknown neighbors → all must be mines!") 🎲 **No-Guess boards** – generator verifies solvability before presenting the board 🔍 **Sub-region mode** (new in v1.10) – for large grids (6³–8³), automatically isolates logically independent zones 📱 **Pure browser** – no download, no account, no ads. Works on desktop and mobile. It's free. Always will be. But if it gives you 20 minutes of genuine brain exercise, a coffee donation (~$2–3) keeps the server lights on. No pressure – the game works either way. ☕ What level breaks you first? 😄 👉 https://minesweeper3d.online/
