I thought I knew how to play Sudoku until I downloaded Good Sudoku+. Most apps just give you a grid and tell you to figure it out. This app actually sits down next to you and explains the 'why' behind every move. It has completely changed my relationship with the game. I went from struggling with 'Medium' puzzles to confidently tackling 'Expert' ones because I finally understand the patterns.
The design is typical Zach Gage—clean, intentional, and slightly playful. The 'Focus' mode, where it highlights all instances of a specific number and dims the rest of the board, is a literal game-changer for my eyes. It’s the most thoughtful digital version of a classic puzzle I’ve ever seen.

When you get stuck, don't just guess. Use the 'Hint' system. Instead of giving you the answer, it will highlight the area and name the technique you need to use. This helps build your 'logical vocabulary' so you can solve harder puzzles without help in the future.
The game automates the tedious parts of Sudoku. You can use 'Auto-Candidates' to fill in all possible numbers, allowing you to focus on the high-level logic rather than bookkeeping. The interface is optimized for speed and clarity.
It's an engine that analyzes your board in real-time to offer hints based on logical techniques rather than just filling in a square.
