I want to launch a clean, intuitive Sudoku puzzle game for mobile devices. The core focus is a classic 9×9 Sudoku experience that looks and feels native on both iOS and Android, so please think in terms of Unity, Godot, or another cross-platform engine you’re comfortable with. Here’s what I need from you: • A solid Sudoku generator/solver that can create endless, valid boards at multiple difficulty levels • A polished touch interface with cell highlighting, note-taking, undo/redo, and an optional hint button • Basic game-loop elements such as a timer, mistake counter, and simple scoring to keep players engaged • Lightweight menus (home, level select, settings) and smooth transitions that respect modern mobile UX guidelines • Builds submitted to TestFlight and Google Play Internal Testing, plus the full project source so I can continue iterating after release Art and audio can be minimal—clean lines, easy-to-read fonts, and a subtle sound set will do for this first version. If you have royalty-free UI kits or audio libraries you already trust, feel free to use them; otherwise we can discuss placeholders. I’ll supply store-listing text and handle the publisher accounts. Your deliverable is the playable game, ready for store submission, along with clear setup instructions. Let me know your preferred engine, estimated timeline, and anything else you need to get started.
