Welcome to Felt Sudoku! These Terms of Service (the "Terms") establish the legal agreement between you and us regarding your access to and use of Felt Sudoku (referred to as the "Game" or the "Services"). Please review this document carefully.
IMPORTANT ARBITRATION NOTICE: UNLESS YOU CHOOSE TO OPT OUT, THESE TERMS CONTAIN A BINDING ARBITRATION CLAUSE AND A CLASS ACTION WAIVER. THIS MEANS THAT ANY DISPUTES BETWEEN YOU AND US MUST BE RESOLVED INDIVIDUALLY THROUGH ARBITRATION RATHER THAN IN COURT. PLEASE REVIEW SECTION 8 CAREFULLY.
The Services are provided by Jiangxi Mengqi Culture Media Co., Ltd., including its affiliates, subsidiaries, directors, and employees (collectively referred to as "we," "us," or "our"). Our registered office is located at Group 1, Houbu Village, Chengjiao Administrative Committee, Anyuan District, Pingxiang City, Jiangxi Province, China.
Within these Terms, "Services" refers to our mobile gaming application, related websites, and any associated features. "Software" encompasses the underlying code, files, scripts, and documentation provided as part of the Services. Any reference to the Services inherently includes the Software unless otherwise specified.
You must meet the age of majority in your jurisdiction (typically 18 years of age) to independently accept these Terms. If you are a minor, you must obtain consent from a parent or legal guardian to play the Game. Parents or guardians who permit a minor to use the Services are bound by these Terms and hold full responsibility for the minor's actions.
We care about your privacy. The ways in which we collect, use, and protect your data are detailed in our Privacy Policy, which is incorporated into these Terms by reference. By playing the Game, you acknowledge that you have read and understood our Privacy Policy.
BY DOWNLOADING, ACCESSING, OR PLAYING THE GAME, YOU LEGALLY CONSENT TO ENTER INTO THESE TERMS ELECTRONICALLY. IF YOU DO NOT AGREE WITH ANY PART OF THIS AGREEMENT, YOU MUST UNINSTALL THE GAME AND CEASE USING THE SERVICES IMMEDIATELY.
Provided you continuously comply with these Terms, we grant you a personal, limited, revocable, non-exclusive, non-transferable, and non-sublicensable license to download and play the Game. This license is strictly intended for your personal, non-commercial entertainment.
You agree not to exceed the scope of the granted license. Specifically, you shall not:
Distribute, host, or broadcast the Game over a network allowing simultaneous multi-device use;
Bypass, disable, or tamper with any security or digital rights management features built into the Software;
Decompile, reverse engineer, translate, or modify the Game, except where applicable laws expressly prohibit such restrictions;
Create, distribute, or use third-party programs to alter the Game experience;
Sell, lease, rent, or sublicense your access to the Game or its assets.
To ensure the best experience, we may continuously deploy patches, updates, or modifications to the Game. These updates may alter gameplay mechanics, change features, or cause temporary downtime. We bear no liability for any perceived losses resulting from such changes.
If you participate in a "beta" or early-access phase, please note that the Game is provided for testing purposes. Features may be incomplete, servers may experience unexpected downtime, and we reserve the right to wipe your gameplay progress without warning to facilitate testing.
By using our Services, you agree that you will not:
Use cheats, automation software (bots), hacks, mods, or any other unauthorized third-party software to modify, tamper with, or reverse engineer any part of the Services or Software;
Use the Services for commercial purposes or in any manner contrary to fair play;
Impersonate any person or entity, or falsely state or misrepresent your affiliation with a person or entity;
Attempt to disable, impair, or destroy the Services or Software;
Post, transmit, or distribute any unlawful, harmful, threatening, abusive, harassing, defamatory, vulgar, obscene, or otherwise objectionable content;
Use the Services in any way not permitted by these Terms or in violation of applicable law.
If we have reasonable grounds to believe you have violated these Terms or engaged in abnormal activities, we reserve the right to take appropriate corrective measures. This may include suspending or terminating your access, resetting your game progress, or reporting severe violations to law enforcement authorities.
All proprietary rights, titles, and interests in the Game—including but not limited to artwork, animations, sounds, logos, branding, and code—are exclusively owned by us or our licensors. Your license to play the Game does not transfer any intellectual property rights to you.
If you are a copyright owner and believe your work is being infringed within our Services, you may submit a formal notification to our designated agent pursuant to the Digital Millennium Copyright Act (17 U.S.C. § 512(c)). The notice must include:
A physical or electronic signature of the copyright owner or authorized representative;
Identification of the copyrighted work claimed to have been infringed;
A description of where the allegedly infringing material is located;
Your contact information (address, telephone number, and email);
A good-faith statement that the use is not authorized by the copyright owner;
A statement under penalty of perjury that the information is accurate.
Please direct DMCA notices to: legal@muduigames.cn. We reserve the right to terminate users who repeatedly infringe copyrights.
Currently, the Game is free-to-play and does not feature in-app purchases, virtual currency systems, or subscriptions. The Game may display third-party advertisements, which are served by advertising networks such as Google AdMob.
If we decide to introduce virtual items or paid services in the future, we will update these Terms accordingly. Any future purchases made within the Game will be subject to the standard refund policies of the applicable app stores. As a general rule, all purchases of virtual items are considered final, non-refundable, and non-cancellable unless mandated otherwise by applicable law.
THE GAME AND SOFTWARE ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS. TO THE FULLEST EXTENT PERMITTED BY LAW, WE EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT GUARANTEE THAT THE SERVICES WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR COMPATIBLE WITH ALL DEVICES.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES (INCLUDING LOSS OF PROFITS, DATA, OR GOODWILL) ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICES.
OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING FROM THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) ONE HUNDRED U.S. DOLLARS ($100 USD) OR (B) THE TOTAL AMOUNT YOU PAID TO US IN THE SIX (6) MONTHS PRECEDING THE CLAIM.
BECAUSE SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES OR LIMITATIONS OF LIABILITY, THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU IN THEIR ENTIRETY.
To the fullest extent permitted by law, you agree to defend, indemnify, and hold harmless Jiangxi Mengqi Culture Media Co., Ltd., its affiliates, directors, and employees from any claims, damages, liabilities, costs, or expenses (including reasonable attorneys' fees) arising from your improper use of the Game, your violation of these Terms, or your infringement of any third-party rights.
These Terms and any related disputes shall be governed by and construed in accordance with the laws of the Hong Kong Special Administrative Region of the People's Republic of China, excluding its conflict of law principles.
We prefer to solve issues amicably. Before initiating any formal legal proceedings, you agree to contact us at service@muduigames.cn to attempt an informal resolution for at least sixty (60) days.
ANY DISPUTE OR CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE GAME SHALL BE RESOLVED EXCLUSIVELY THROUGH FINAL AND BINDING ARBITRATION, RATHER THAN IN COURT.
The arbitration shall be conducted in English before a single arbitrator. Unless you and we agree otherwise, the proceedings shall take place in Hong Kong via videoconference or in person. The seat of arbitration shall be Hong Kong. The arbitration shall be administered by the Hong Kong International Arbitration Centre ("HKIAC") in accordance with the HKIAC Administered Arbitration Rules in force at the time of commencement of the arbitration.
CLASS ACTION WAIVER: YOU AGREE TO WAIVE ANY RIGHT TO A JURY TRIAL. ALL DISPUTES MUST BE ARBITRATED ON AN INDIVIDUAL BASIS. YOU MAY NOT PARTICIPATE IN A CLASS ACTION, COLLECTIVE ACTION, OR REPRESENTATIVE PROCEEDING AGAINST US.
You may opt out of this arbitration agreement by notifying us in writing at legal@muduigames.cn within thirty (30) days of your initial acceptance of these Terms. Your notice must clearly state your intention to opt out and include your full name and contact information.
Notwithstanding the arbitration clause, either party retains the right to bring an individual action in small claims court or seek injunctive relief in a court of competent jurisdiction regarding intellectual property infringement.
We maintain the right to suspend or terminate your access to the Game at our sole discretion, at any time, and without prior notice, particularly if we believe you have breached these Terms. Upon termination, your license to play the Game revokes immediately. Clauses intended to survive termination (such as Intellectual Property, Limitation of Liability, Dispute Resolution, and Indemnification) shall remain in full effect.
We may revise these Terms periodically to reflect changes in our business or legal obligations. If we make material changes, we will strive to notify you (e.g., via an in-game pop-up or app update). Continuing to play the Game after the revised Terms go into effect implies your acceptance of the modifications.
The English version of these Terms serves as the legally binding document. Any translations are provided merely for convenience.
You may not transfer or assign your rights under these Terms without our written consent. We may freely assign our rights and obligations to third parties.
These Terms represent the complete understanding between you and us regarding the Game, superseding any prior agreements.
If any provision of these Terms is deemed unlawful or unenforceable by a court, that specific provision shall be severed, and the remaining provisions will continue in full force.
Our delay or failure to enforce any right or provision under these Terms does not constitute a waiver of that right.
For any questions or concerns regarding these Terms, please contact us at: service@muduigames.cn.
