How the game works
Stack Master is a hyper-casual tower-stacking game. You tap to drop a moving neon block onto the tower; any overhang is sliced off. All gameplay logic, scoring, and visuals run entirely on your device. Nothing about your game play is uploaded.
Network connections
Gameplay is fully offline. The internet is used only by Google AdMob to load ads (see “Advertising” below). The app requires an active internet connection to open — you will see a “No internet connection” screen when offline.
Permissions the app requests
- Internet / network state — required to request ads.
The app does not request location, contacts, microphone, camera, storage, or any other sensitive permission.
Advertising
Stack Master shows ads provided by Google AdMob in four formats: banner (small strip at the bottom of every screen), interstitial (full-screen ad shown occasionally after a game ends), app-open (full-screen ad when you bring the app back to the foreground), and rewarded (an optional full-screen ad you can choose to watch to continue your run after a game over). Google’s advertising SDK collects and processes limited data — for example, your device’s advertising identifier and approximate IP-based location — to serve and measure ads. This is governed by Google’s policies:
If you live in a region where consent is required (the EEA, UK, Switzerland, or a US state with applicable privacy law), the app uses Google’s User Messaging Platform (UMP) or sets npa=1 (non-personalized ads) so it stays compliant with GDPR / UK GDPR / CCPA.
Children
This app is not directed at children under 13 and is not classified as a “family” app on Google Play.
