Play classic Sudoku and 12+ variants (Killer, X-Sudoku, Thermo, Arrow, Anti-Knight, Palindrome) online for free at SudoZen. Step-by-step solver with logical hints, pencil marks, cell colors, and interactive strategy guides for all skill levels.
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?
