ZeroOneFlow vs Unblock my Sudoku

Infinity begins in binary. From the silent dance of 0 and 1, a universe unfolds. 0 and 1. Nothing more. Yet from them, everything.

Unblock My Sudoku is your ultimate companion for completing sudoku puzzles. Instead of staring at a frustrating grid for 10 minutes and giving up, use your iPhone or iPad camera to scan your partially solved puzzle and get back on track. Rather than simply telling you a number for a cell, this app acts as a logic tutor. It nudges you forward with progressive, visual hints. It starts by highlighting the cell you can solve, then indicates the relevant row, column, or box, and finally shows the exclusions that lead to the answer. You get unstuck while learning the underlying patterns to become a better player. KEY FEATURES • Smart Camera Scanning: Instantly digitize partially solved puzzles from books, newspapers, or printouts. • Progressive, Educational Hints: Learn how to infer the next number with simple, visual instruction that steps you through the logic. • Master All Difficulties: Works with all levels of difficulty, from easy all the way up to diabolical. Supports a full suite of candidate elimination techniques, taking you from basics like Pointing Pairs and XY-Wings, to intermediate strategies like Two-String Kites, all the way to advanced Alternating Inference Chains (AIC). • Learn on Your Own Puzzle: It’s hard to grasp a new strategy from a random example online. The app features a clean, text-light interface that teaches you visually, applying new techniques to the exact puzzle you’ve been sweating over so you can finally get out of that jam. • Offline Privacy: All puzzle analysis, OCR processing, and hint generation happen entirely on-device. PRICING Download for free and get 3 free hints every week. If you love the app and want unlimited hints, you can unlock them forever with a single, one-time purchase. (Optional: You can choose to help improve the app's text recognition by anonymously sharing images of individual cells. This is completely optional, and the app functions fully offline without it.)
