Hi PH! 👋 I built SudoZen because I wanted a sudoku app that actually teaches you why a move works, not just whether it's right. What's inside: 🧩 Daily puzzle — everyone gets the same deterministic puzzle each day ⏱ Timed mode — pick difficulty, race the clock (Easy 10min → Expert 40min) 🤖 Step-by-step solver — explains every logical deduction (X-Wing, Swordfish, etc.) 🎨 12+ variants — Killer, Thermo, Arrow, Palindrome, Anti-Knight, and more 📱 No ads, no signup — just play The solver was the hardest part — I rewrote it from Rust to TypeScript so it runs entirely in-process on the server with zero binary dependencies. Happy to answer questions about the engine or the tech stack! Would love your feedback — what's your favorite sudoku variant?
