Sky Stack Support

Sky Stack is a one-tap precision stacking game for iPhone.

How to Play

Tap Play, then tap to place the moving block.
Overhanging portions fall away, leaving a smaller landing for the next block.
Perfect placements preserve width. Perfect streak milestones can recover width while increasing the speed pressure.
Build as high as possible. A complete miss ends the run; Play Again starts another climb.

Audio / Visual Effects / Haptics

Open Settings from Home to turn Audio, Visual Effects and Haptics on or off independently. Audio Off silences all app music and sound effects.

Game Center

Game Center is optional. Core gameplay, your local best, local achievements and unlocked themes work without it. The online leaderboard and Game Center achievements use Apple’s Game Center service.

Open Leaderboard from Home to access Game Center. Online features require an available connection and Game Center sign-in.

Troubleshooting

Close and reopen Sky Stack.
For missing audio, check Audio in the app’s Settings, device volume, silent mode and your selected audio output.
If the leaderboard is unavailable, check your connection and Game Center sign-in in iPhone Settings. You can keep playing offline.
Sky Stack 1.0 requires iOS 17 or later. Check that your device runs a supported version.
