Why I built Animal Sudoku without a single ad

Screen time for children often causes issues due to free games bombarding them with ads. These ads interrupt their focus with flashing banners and loud noises. The author built Animal Sudoku as a solution to provide a distraction-free environment for logical thinking. The issue became more apparent when the author noticed children being exposed to video ads, intrusive "Upgrade Now" buttons, mid-game pop-ups asking for ratings, and hidden data collection on young minds.

As a parent and engineer, the author couldn't ignore this practice and decided to create a better alternative.

Animal Sudoku is a game designed with children in mind, offering three difficulty levels and six animal characters in color-coded zones. It features smart hints, auto-save, gentle background music, and confetti celebrations upon completing a puzzle. The game has no ads, third-party analytics, accounts, internet connection requirements, video-unlocking mechanisms, or data collection. It's fully compliant with COPPA regulations as it doesn't collect any data.

The app is completely free and doesn't require any purchases for the full experience. The author focused heavily on accessibility, incorporating VoiceOver, TalkBack Support, Voice Control, haptic feedback, and large touch targets for easy navigation. If you have young ones in your life, the author invites you to try Animal Sudoku and provide feedback on your experience. The app is available on the App Store for free and an Android version is in development.
