This document explains the legal terms and conditions that apply when you use the YYG Platforms (as explained below).


If you want to find out about the terms and conditions applying to products or services which you license via YYG Platforms, please see the relevant End User Licence Agreement (which may be the YoYo Games Platforms Default Publisher EULA or the relevant publisher’s own EULA) on the webpage for that product or service. If you are interested in distributing products or service via the YYG Platforms, check out the YoYo Games Platforms Publisher Agreement.

"Publisher": means the person (which includes any person, company or other legal entity) that publishes any Publisher Property.

"User Agreement": means this document and any documents that form part of it or are related to it, as updated from time to time.

    • 1.1. Acceptance of User Agreement. This User Agreement is a legally binding contract between Customers (that’s you) and YoYo Games (that’s us) regarding your use of the YYG Platforms and Publisher Property accessed via them, including but not limited to your use of GameMaker, licensing of software products or services via the GameMaker: Player or GameMaker: Marketplace. Please review it carefully. You are welcome to contact us at if you have any questions or comments about this User Agreement, but in any event your continuing usage of YYG Platforms will demonstrate your approval of this User Agreement.
    • 1.2. Access for adults only or with adult approval. To accept this User Agreement and use the YYG Platforms, you must be at least 18 years of age (or whatever is the age of legal majority in your country, if it is not 18). If you are not an adult, then your usage is at our discretion and you will need your parent’s or guardian’s approval and your acceptance of this User Agreement or your continuing usage of YYG Platforms will demonstrate you have acquired such approval.

    • 2.1. We may make any YYG Platform (or parts of it) available as a pre-release/alpha/beta version(s) from time to time. This means that it would be released with some or most of its features, but it would not be complete and would still be subject to testing/further development – therefore it may still contain bugs or errors. It is likely to therefore need patching and updating too. The pre-release period will last until we decide to end it. We do not make any promises about (or accept any liability for): the pre-release version’s contents, what it does, how it does it, how well it does it or about future updates, patches or subsequent versions: you must accept it ‘as is'.

    • 3.1. Access requirements. In order to access certain YYG Platforms and obtain access to certain Publisher Property, you may need to open a YYG Platforms account, have an appropriate level of GameMaker licence (which will be notified to you in relation to appropriate YYG Platforms) and be in good standing with YoYo Games. We may also implement verification and Digital Rights Management technology if we consider it necessary. You will need an Internet connection in order to access YYG Platforms and Publisher Property. System requirements for YYG Platforms and (where available) for Publisher Property will be provided on the applicable YYG website.
    • 3.2. Use of YYG Platforms and Publisher Property. You are granted a revocable, limited, worldwide and royalty-free licence to use the YYG Platforms for authorised purposes, including to browse, locate, access and use Publisher Property for use with YYG Platforms. Some Publisher Property may be created by YoYo Games and others may be created by third party Publishers. Some may be made available to you for free while others may be licensed for money. You must access the YYG Platforms solely through authorised means (e.g. via GameMaker or via our websites or other methods we may roll out over time) and must not attempt to access the YYG Platforms through any other means, in particular not through automated means like scripts or crawlers or similar technology.
    • 3.3. Other uses of Publisher Property. IF you hold the appropriate level of GameMaker: Studio licence, you may export your content to third party platforms such as iOS and Ubuntu as permitted by us (further details can be found at In no circumstances are you permitted to, at the request of a third party, export that third party’s content. Nor can you request a third party who holds an appropriate level of GameMaker: Studio licence to carry out such activities on your behalf.
    • 3.4. Responsibility for Publisher Property. Publishers are responsible for how their Publisher Property is displayed and marketed via the YYG Platforms. We take no responsibility or liability for Publisher Property or how they are displayed or marketed, what they do or do not contain or how they perform. All such issues should be addressed further in the relevant EULA (which will be either the YoYo Games Platforms Default Publisher EULA or the relevant publisher’s own EULA, depending on which the relevant Publisher has chosen to apply) and in any event are a matter for you and the Publisher.
    • 3.5. Your responsibility. You are solely responsible for your own use of the YYG Platforms and for any breach of your obligations under this User Agreement.
    • 3.6. Updates. From time to time, Publisher Property which is software may be subject to updates (such as bug fixes, patches, new versions and enhancements). You can set in GameMaker whether to download these updates automatically or manually. Please note we may remove any Publisher Property which no longer works with the YYG Platforms from the YYG Platforms.
    • 3.7. Provision of information. In order to access the YYG Platforms fully, you may be asked to provide accurate information about yourself such as your name, address and billing details. Any information about you will be held by us under the terms of our Privacy Policy.
    • 3.8. Payments. For YYG Platforms and for Publisher Property which is made available via the YYG Platforms for money, you can use PayPal and potentially other payment methods that we may change, add or remove over time. Your use of any payment services will be subject to the terms and conditions of the relevant payment processor. In addition, purchases may include sales tax, including value added tax (VAT) or regional equivalent if applicable in your country. In order to assess the correct level of VAT you need to pay, we will need to collect information about your country of residence (this is further described in our Privacy Policy). Please make sure you give us accurate information about your country of residence, since if we cannot corroborate your country of residence we will be obliged to charge you the highest level of applicable VAT.
    • 3.9. Compliance. You are responsible for compliance with all local laws, regulation and industry practice when accessing and using the YYG Platforms and any Publisher Property.
    • 3.10. Ratings. You may be able to rate and review applicable Publisher Property via the YYG Platforms. Please be honest and constructive in your ratings and bear in mind that you are responsible for your rating and any comments you make about the Publisher Property.

    • 6.5. Force Majeure. Neither party shall be liable for any failure to fulfil its obligations under this User Agreement as a result of force majeure and in such circumstances the time for performance shall be extended by a period equivalent to the period during which performance of the obligation has been delayed or failed to be performed.

In no event will YoYo Group be liable to you for any loss of profits, charges or expenses, loss of data or any corruption or loss of information, or any loss of business opportunity, or any special, indirect, punitive, exemplary or consequential loss or damage or disruption of any kind, in any case, whether based on breach of contract, tort (including negligence or breach of statutory duty), misrepresentation, restitution or otherwise whether or not the relevant party has been advised of the possibility of such damage. The foregoing limitations will survive and apply even if any limited remedy specified in this User Agreement is found to have failed of its essential purpose. Nothing in this User Agreement purports to limit or exclude either party’s liability: (i) for fraud, fraudulent misrepresentation or wilful misconduct; (ii) for death or personal injury caused by that party’s negligence; or (iii) to the extent otherwise not permitted by law.
