What this covers

These terms explain the rules for using the app, including gameplay access, advertising, optional purchases, updates, intellectual property, and liability.

Key point

Stackd is intended for personal, non-commercial use. Use of unfair manipulation, automated systems, or exploitation of technical issues is not permitted.

1. Scope

These Terms of Use govern your use of the mobile application Stackd – Block Puzzle Game (the “App”). By downloading, installing, or using the App, you agree to these Terms.

2. Service Description

The App is a casual block puzzle game. Users place shapes on a grid to complete rows or columns and earn points. The App is generally available free of charge.

3. Advertising

The App may display advertisements, for example banner ads, interstitial ads, or rewarded ads. Watching rewarded ads is optional and may provide in-game benefits.

  • Advertising helps finance the free availability of the App.
  • Users can decide whether to interact with optional rewarded advertisements.

4. In-App Purchases

The App may offer optional in-app purchases, for example for coins, unlocks, or other additional content. Such purchases are voluntary and processed through the relevant app store provider.

Availability, pricing, and presentation of purchasable content may change over time where reasonable.

5. Eligibility

The App is not specifically directed at children under the age of 13. Where required by local law, minors may use the App only with the consent of a parent or legal guardian.

6. User Conduct

You agree not to:

  • modify, reverse engineer, decompile, or manipulate the App,
  • use automated systems such as bots, scripts, or macros to influence gameplay or scores,
  • exploit bugs or technical vulnerabilities to gain unfair advantages.

In the event of violations, we may take reasonable measures, including limiting access to certain features.

7. Availability and Updates

We aim to keep the App available, but we do not guarantee uninterrupted operation. Maintenance, updates, or technical problems may lead to temporary interruptions.

We may update, modify, or discontinue features of the App where this is reasonable for users.
