Stack to Match Support

Have a question about Stack to Match? Contact KNOO Studio for help or to share your feedback.

How We Can Help

• Gameplay issues or questions about a level.
• Technical problems, including crashes or display issues.
• Advertising issues or missing rewarded-ad benefits.
• Privacy questions or concerns.
• General feedback and suggestions.

To help us understand an issue, include your app version, iOS version, device model, and a short description of what happened. For a gameplay or reward issue, the level or game mode can also be helpful. You may attach a screenshot if useful; please avoid sharing sensitive information.

Quick Answers

How do I complete a level?

Match equal numbers in the same row or column with no tile or wall between them. Tap a tile and its partner, drag to merge, or flick toward a match. Two 1s become a 2; two 2s become a 3. Leave just one tile to finish. Restarting a puzzle is free.

Can I play offline?

Puzzles work offline. Advertisements and their rewards require an internet connection and an available ad. If an ad cannot load, you can continue playing or restart the puzzle.

Where is my progress saved?

Progress and preferences are saved on your iPhone. Deleting the app removes its local data, so please contact us before reinstalling to troubleshoot a problem.

Why is the music silent?

Check Background music and its volume in the game’s Settings, then check your iPhone volume and Silent Mode. Music pauses while the app is in the background or an ad is playing.

Advertising and Reward Issues

To report an inappropriate advertisement or a missing reward, email us with a short description, the approximate time it appeared, and whether it was a banner or rewarded ad. Include the advertised app or product and a screenshot if you can safely capture one. You do not need to click the advertisement to report it.

For a missing reward, mention whether you chose a Hint or Undo reward and what happened after the ad. Please do not reinstall the game as a troubleshooting step: deleting the app removes locally saved progress and preferences.
