1. Scope

These Terms apply to all relations between us and the user concerning use of the App. Handling of user information is governed by our separate Privacy Policy, which forms part of these Terms.

The App is obtained, and purchases are made, through the App Store or Google Play. The conditions of those stores are set by their operators, not by us. Where these Terms conflict with a store's terms, the store's terms prevail as between the store and the user.

2. Conditions of use

The App may be used only as a legitimate copy obtained from the App Store or Google Play. Supported OS versions are as listed on the stores; we do not warrant operation in any other environment.

Minors should use the App and make in-app purchases only with the prior consent of a parent or guardian. Parents and guardians can check whether a child is able to make purchases using each store's purchase controls (Screen Time on the App Store, "require authentication for purchases" on Google Play, and similar).

The App automatically shows a popup offering "Continue with your score" whenever you get stuck. That item is a consumable bought one use at a time, with no limit on how many times it can be bought. If a minor will be using the App, please review the purchase controls above as well.

Even where a purchase has been made by a minor, whether a refund is available and how to request it follow the terms and procedures of the relevant store (section 5).

3. Fees

The App itself is free. The realms DUSK (4×4) and ROYAL (5×5) can be played to their final level without any purchase. Optional in-app purchases are also offered (section 4).

4. In-app purchases

The items sold in the App are as follows.

ItemTypeDetails
Remove ads for 1 week Consumable (time-limited) Hides all ads in the App for 7 days from purchase. During that period, undoing a move also requires no ad
Continue with your score Consumable (single use) Continue from a stuck board on a fresh board, keeping your score, that level's target and your move count. It is bought from the popup shown when you get stuck, not from the shop
Unlock FOREST (6×6) Consumable (time-limited) Gives access to the 6×6 board and its own separate records for 30 days from purchase
Unlock EMBER (7×7) Consumable (time-limited) Gives access to the 7×7 board and its own separate records for 30 days from purchase
Unlock ECLIPSE (8×8) Consumable (time-limited) Gives access to the 8×8 board and its own separate records for 30 days from purchase. This realm also spawns the odd tiles 3 and 6; odd tiles never merge with even ones

Prices are those displayed by each store and vary by country or region. Please check the price shown in the App or on the store before purchasing. Payment is processed through the stores; we never receive or store payment details such as credit card numbers.

Because we operate no server, purchase state is recorded only on the user's device. This carries the following limitations.

5. Refunds

In-app purchases are, as a rule, non-refundable. This includes, but is not limited to, the following cases.

Whether a refund is available, and how to request one, follow the terms and procedures of the App Store or Google Play. We do not process payments and therefore have no ability to issue refunds. Please direct refund requests to the relevant store.

Statutory rights are unaffected. This section does not limit any right granted to users by consumer protection law or other applicable law. Where a refund or other action is required by law, we will comply with that law.

6. Changes, suspension and discontinuation

We may change the content of the App, suspend it, or discontinue it entirely, without prior notice to users. This includes, but is not limited to, the following cases.

If the service ends, the App will no longer be obtainable, and even an already installed copy may become unusable depending on OS or store behaviour. In that event, no refund or other compensation is given for purchased items or remaining time (section 5).

Where we decide to discontinue the App, we will endeavour to give advance notice on the store listing or on this site so far as reasonably possible, but we do not guarantee this.

7. Data storage and loss

The App's records and purchase state are stored encrypted only on the user's device. No data is stored on any server of ours. Data is therefore lost, and cannot be restored by us, in the following cases.

8. Advertising

The App displays ads via Google AdMob. The content of those ads is decided by the ad provider, not selected by us. We accept no responsibility for the content of ads, or for the services or products of advertisers.

If you would rather not see ads, please purchase "Remove ads for 1 week" (section 4).

9. External services

The App embeds the following external services.

Use of these services is subject to the terms and privacy policies set by their respective providers. We accept no responsibility for specification changes, suspension or discontinuation, or faults in these services, or for any loss suffered by users as a result.

10. Prohibited conduct

In using the App, users must not do any of the following.

11. Intellectual property

Intellectual property rights in the programs, images, text and all other content contained in the App and this site belong to us or to the rightful rights holders. These Terms do not transfer any of those rights to the user.

12. Disclaimers

We do not warrant that the App is fit for any particular purpose of the user, that it has the functionality the user expects, that it operates correctly on every device and OS, or that it will be free of defects.

We accept no responsibility for loss suffered by users arising from use of, or inability to use, the App, except where caused by our wilful misconduct or gross negligence.

Even where we are liable, the scope of compensation is limited to the amount the user has paid in respect of the App up to the time the loss occurred. This does not apply where consumer protection law or other applicable law does not permit our liability to be excluded or limited.

13. Changes to these Terms

We may change these Terms in response to changes in law, changes to the App, or where we otherwise judge it necessary. Changes take effect when posted on this page. For significant changes we will give notice in the App or in the store release notes.

Continuing to use the App after a change is deemed acceptance of the changed Terms. If you do not accept the changes, please stop using the App and uninstall it.

14. Assignment

Users may not assign, transfer or pledge their position under these Terms, or any rights or obligations under them, to a third party without our prior written consent.

If we transfer the business relating to the App to a third party, we may transfer to the transferee our position under these Terms, our rights and obligations under them, and information relating to users, as part of that business transfer, and users consent to this in advance.

15. Severability

If any provision of these Terms, or any part of one, is held invalid or unenforceable by law, the remainder of these Terms and the remainder of that provision continue in full force and effect.

In that case, we and the user shall endeavour to agree on a valid and enforceable provision that comes as close as possible to the intent of the part held invalid or unenforceable.

16. Governing law

These Terms are governed by and construed in accordance with the laws of Japan.
