An operator paying for custom slot game software doesn’t automatically mean that the source code is owned by the operator. Ownership depends on the development agreement, intellectual property terms, source-code rights, licensing provisions, and any third-party assets or technology used. It also depends on the contract between the operator and provider. The developer may provide you with ownership of intellectual property, or may only grant you a licence to use it.
In short,
Game ownership ≠ source-code ownership ≠ licensing rights ≠ distribution rights
This blog explains what “owning a custom slot game” means for operators in custom slot game development and the different types of ownership an operator can have.
What Does “Owning a Custom Slot Game” Actually Mean?
Let’s understand it through different forms of ownership.
Intellectual Property Ownership
Intellectual Property (IP) ownership in custom slot game development is the legal right to own, use, modify, and commercially exploit the slot game’s assets, depending on the terms of the development agreement. This may include game concept, original game artwork, game animations, audio, UI/UX, game mathematics, code, and branding.
Source Code Ownership
Source code ownership in custom slot game development means owning the game’s underlying code, which includes gameplay logic, bonus distribution, features, integrations, and backend components. The operator owns the source code and can modify it as per the game’s and business requirements. A licensed code grants ownership of the code for usage rights, while an assignment transfers ownership of the agreed intellectual property rights. The operator can ask or hire a developer who can modify the source code if the agreement grants such permissions.
Commercial Usage Rights
Commercial usage rights grant operators the right to use a custom slot game for business purposes such as launching the game, gaining access to profits, or distributing it in different markets. The duration of the rights depends on the agreement between parties. It also includes usage rights for brands, given that the operator has multiple brands. The agreement also specifies whether the operator can use it in different jurisdictions and platforms.
Distribution Rights
Distribution rights involve the agreement between both parties on how and where the custom slot platform can be distributed to casino operators, platforms, and aggregators. The buyer can launch the game on its platform subject to the agreement. The buyer can grant other operators rights to use the game only if the agreement explicitly allows sublicensing or onward licensing.
Who Usually Owns a Custom Slot Game?
Ownership of a custom slot game depends on the agreement between the operator and the slot game development company. Before development begins, operators should clarify each clause of the agreement about who owns the source code, game assets, mathematics, and reusable technology. Some of the main contractual models include:
Full IP Assignment to the Client
Under full IP assignment, the development company transfers the ownership of intellectual property rights to the operator, typically through a written contract. The transfer includes IP rights such as source code, game artwork, game animations, sound assets, and custom gameplay features.
Developer Retains IP and Grants a License
In this agreement model, the development company retains ownership of the game’s intellectual property and offers a license to use it under specified terms. The permission terms may include locations, duration, platforms, and the number of casino brands the operator can use the license for.
Shared or Limited Rights
Shared or limited rights allow both the operator and developer to own some parts of the game in different ways. For example, the operator may own custom artwork or designs, but the developer reserves the rights to a reusable game engine, frameworks, or development tools. In this way, both parties own some parts of the game.
Exclusive Licensing
An exclusive licensing right grants operators exclusive rights to use, license, or commercialize a game within a defined scope, such as a specific territory, platform, or period. The operator may own the IP rights, but the developer may restrict them to provide it to other operators within agreed terms. It should be noted that exclusive rights and ownership are not the same thing.
What Parts of a Slot Game Can Be Owned or Licensed Separately?
| Component | Possible Ownership/Right | What to Clarify |
|---|---|---|
| Source code | Assignment or license | Can the client access and modify it? |
| Game artwork | Assignment or license | Can assets be reused? |
| Game animations | Assignment or license | Third-party restrictions |
| Sound/music | License often applies | Commercial usage rights |
| Game mathematics | Contract dependent | Ownership and reuse |
| Game mechanics | May not be exclusively owned | Patent/copyright considerations |
| Brand/trademark | Usually separate | Who owns the brand? |
| APIs/integration code | Contract dependent | Reuse and modification |
| Game engine | Often developer-owned | Whether sublicensing applies |
| Third-party SDKs | Usually licensed | Transfer restrictions |
Does Paying for Custom Slot Game Development Mean You Own the Source Code?
Not necessarily. An operator paying for custom slot game development doesn’t automatically own the source code. Payment terms cover development services, while ownership depends on the contract, applicable law, and any intellectual property (IP) assignment provisions. An operator may receive a completed game but only have permission to use it rather than own or modify its underlying code.
The contract should distinguish between these key terms:
- Work made for hire where legally applicable: As the agreement says, it clearly states that the work is done on hire, and the client is treated as the legal author or owner of qualifying work.
- Assignment of rights: Transfers specified IP rights to the client after development. This agreement should clearly mention what rights are included.
- License: Grants permission to use the game without necessarily transferring ownership to the operator.
- Perpetual license: Allows the operator to use for unlimited time, as given in the agreement, but it doesn’t automatically mean ownership of the code.
- Exclusive license: It provides the operator with exclusive license rights to use the license under agreed terms.
- Non-exclusive license: Allows the operator to use the game while the developer can generally license it to other clients as well.
- Right to modify: Allows operators with the right to edit the source code based on agreement.
- Right to sublicense: States whether the operator can offer the license to other casino operators or aggregators.
What Should Be Written Into a Custom Slot Development Agreement?
Before development begins, make sure to check these terms in the agreement with the slot game development company.
IP ownership clause
Who owns the final deliverables? Is it you or the provider who owns the full IP rights?
Source code clause
Is source code included in the ownership of the slot game platform?
Modification rights
Can the client modify or appoint another developer?
Exclusivity clause
Can the developer sell or license a similar game elsewhere? Check for an exclusive rights clause where it should clearly mention what exclusive rights the developer provides you over the platform.
Territory
Which countries/markets are covered? This is very important as it defines the extent of the market you can cover and launch your game.
Duration
Is the right perpetual or time-limited? Check if the agreement is for an indefinite duration or a fixed duration
Distribution rights
Can the operator license the game to other businesses? This matters if you own more than one brand or platform.
Third-party components
Which parts cannot be transferred? Check for all owned third-party rights provided to you by the developer.
Maintenance and updates
Who owns improvements and future versions? Check for after-launch services if there is any.
Termination
What happens when the contract ends? Check for renewal terms and the process that is involved.
Can a Developer Reuse a Custom Slot Game for Another Casino?
The rights to reuse a custom slot game for another casino depend completely on the contract and rights granted. If the client receives full IP ownership or exclusive rights, reuse may be restricted. The agreement should specify whether the client has exclusive rights or non-exclusive rights and what components of the game can be reused by the developer without the permission of the operator.
The reusable components of a custom slot game development may include:
- Identical game: Whether the distribution of the same game to another casino is permitted or not.
- Similar mechanics: Whether similar or the same game mechanics can be used or not.
- Reskinning: Whether reskinning is allowed by creating new versions of the game.
- Artwork reuse: Whether art or animations reuse is permitted or not.
- Source-code reuse: Whether the developer can reuse the source code for another casino platform.
- Math-model reuse: Slot game mathematics such as RTP and volatility can be reused.
- White-label versions: Developers may offer the same underlying game to multiple operators with different branding or visuals.
- Exclusive vs non-exclusive contracts: The contract clearly defines exclusivity offered by the developer to the operator.
What Happens to the Slot Game If the Development Contract Ends?
When a contract ends, there are various scenarios that can happen depending on the contract terms. Some scenarios include:
Client owns the IP
The client may retain agreed ownership. The operator may completely own the intellectual rights of the platform for indefinite periods.
Developer owns the IP
The developer owns the IP, but the client may continue the license as per agreed terms.
Source code is licensed
When the source code is licensed rather than transferred to the client, termination provisions become critical. The contract should clarify whether the operator can continue using the slot game after the agreement ends, or what happens to source code ownership.
Hosting remains with developer
When hosting remains with the developer, source code ownership does not necessarily give the operator full technical control over the game. An operator can own the source code but still depend on the developer for server access and hosting rights.
Ownership vs Licensing vs Exclusivity: What Is the Difference?
| Right | What it generally means |
|---|---|
| Ownership | Legal rights in the underlying asset, subject to the agreement and applicable law |
| License | Permission to use an asset |
| Exclusive license | Permission reserved exclusively to one party within defined limits |
| Non-exclusive license | Multiple parties may receive usage rights |
| Distribution right | Permission to distribute the game |
| Modification right | Permission to change or adapt the asset |
| Sublicensing right | Permission to grant rights to another party |
What About Third-Party Assets Used in a Custom Slot Game?
A developer cannot necessarily transfer rights it does not own. Some third-party components used for custom slot game development cannot be owned by the developer which rights cannot be transferred to operator. This includes:
- Music libraries
- Fonts
- Stock images
- Animation libraries
- Game engines
- SDKs
- APIs
- Software libraries
- Middleware
- AI-generated assets where applicable
- Licensed trademarks/characters
