A simple Sudoku game. I built it for myself and my family to enjoy together. No excessive ads during gameplay—just a quiet, comfortable space to focus on the puzzle. To support healthy screen habits for kids, the app includes Parent Settings. When you first install the app, a parent can set: - How many rounds can be played - A waiting time between rounds This helps children naturally build the habit of self-control. Your play records are also saved, so you can look back after finishing a game and keep the fun going. [Why Sudoku is great] - Improves logical thinking - Strengthens concentration - Develops problem-solving skills - Trains memory - Enhances number sense Short sessions, deep focus. Enjoy a healthy brain game that the whole family can play together.
