Hi Product Hunt! 👋 I’m Roman, the solo developer behind Jigsudo. I’ve always loved classic brain teasers like Jigsaw puzzles and Sudoku, so I decided to see what would happen if I combined them into a single experience. What started as a simple prototype evolved into a 6-stage daily mission (Memory, Jigsaw, Sudoku, Peaks & Valleys, Number Search, and The Code) that all take place on a single, unified board. As a technical challenge, I built Jigsudo as a Single Page Application (SPA) using purely Vanilla JS, no heavy frontend frameworks, with Firebase handling the cross-device syncing and global leaderboards. The game generates a new puzzle procedurally every day for the whole world. It’s 100% free, and you can jump right in as a guest without signing up. You can try out the Basic Edition on itch.io, or play the Full Version on the official website. I’d love to hear your feedback on the difficulty curve, the transition between stages, or the UI layout! (Tip: I highly recommend doing the interactive tutorial and also trying a past challenge from the History tab first before attempting today's challenge). 🧩
