Every Sudoku app makes you tap tiny buttons or number pads, breaking your concentration dozens of times per puzzle. Paper Sudoku eliminates this with handwriting recognition. Draw numbers naturally - our AI fills them instantly. No attention switching. Just pure flow. Notes, streak tracking, resume-anytime and detailed stats sit behind that same simple input model so your practice becomes measurable, not just habitual. Free (limited time). No ads. iPhone only.

Hey Product Hunt! 👋 - I am excited to launch Paper Sudoku. I play puzzles every day - LinkedIn Games, NYT Wordle, Apple News. Sudoku is my favorite, but it always had the most friction. Traditional Sudoku apps make you context-switch dozens of times per puzzle - eyes to grid, eyes to number pad, tap, back to grid. Paper Sudoku eliminates this. Draw numbers with your finger using muscle memory without moving eyes off the grid. AI recognizes them instantly. Stay in flow. Handwriting recognition based on Apple's Core ML and uses image classification model. It's free right now (limited time). Would love to hear what you think, especially if you're a regular Sudoku player! Happy to answer questions about the tech or design choices. Do take a look If you solve puzzles to get faster, build a streak, or just stay in flow on your commute or lunch break, handwriting input changes the experience: faster entry, fewer mistakes from UI friction, and clearer progress signals to guide improvement.
