A game development contract protects both you and the developer by spelling out exactly what gets built, when, and for how much. Without one, scope creep, missed deadlines, and disputes over ownership can turn your dream project into a nightmare. Let's walk through the critical clauses you need before signing anything.
Scope of Work: Be Ruthlessly Specific
The scope section is your contract's backbone. Instead of "create a mobile game," specify the platform (iOS, Android, both), game genre, target audience, and core features. List exactly what's included: character animations, UI design, sound effects, multiplayer functionality—whatever applies to your project.
Define what's not included too. If you want voice acting, premium art assets, or post-launch support, say so explicitly. Many developers charge $15,000–$50,000 for indie mobile games and $100,000+ for mid-scale titles, with scope directly affecting price. A vague contract invites the developer to interpret your vision differently and charge accordingly.
Deliverables and Milestones
Break the project into concrete milestones with specific deliverables. A typical timeline might look like:
- Milestone 1 (Week 2): Game design document, technical architecture approved
- Milestone 2 (Week 6): Playable prototype with core mechanic
- Milestone 3 (Week 12): Feature-complete beta build
- Milestone 4 (Week 16): Final build, bug fixes, platform submission
Each milestone should have a delivery date and acceptance criteria. For example, "core gameplay loop runs at 60 FPS on target hardware" is measurable; "game feels fun" is not. Payment is typically tied to milestone completion—paying 20–25% upfront, then larger chunks on delivery.
Intellectual Property Rights
This clause determines who owns the finished game and its assets. Most developers will retain rights to their proprietary engine code or reusable libraries, but you should own the final game and custom assets created for your project.
Clarify ownership of:
- Game source code and executables
- Original artwork, music, and animations
- Story, characters, and game mechanics
- Marketing materials
If you're licensing middleware (like Unity, Unreal, or Wwise), understand the licensing restrictions—many have revenue-sharing clauses or distribution limits. Get this in writing before development starts; retroactively changing IP ownership is messy and expensive.
Revision Rounds and Change Requests
Define how many revision rounds are included. A typical contract might include two rounds of minor revisions per milestone, with additional changes billed at hourly rates ($50–$150/hour for game developers, depending on experience and location).
Create a change request process: any scope additions must be documented, approved, and priced before work begins. Without this, you'll fund endless tweaks, and the developer loses predictability on their end date and budget.
Timeline and Penalties
State the project start and expected completion date. Include a buffer—games always take longer than estimated. A 12-week project should realistically plan for 14–16 weeks.
Address penalties for late delivery only if both parties agree. Some contracts include:
- Milestone extensions without penalty (realistic for software)
- Reduced payment if developer misses deadlines (rare and contentious)
- Delay compensation if you're paying per milestone and can't launch on time (more common in larger contracts)
Most indie contracts simply allow for reasonable schedule adjustments if scope changes or unforeseen technical issues arise.
Payment Terms and Dispute Resolution
Establish a payment schedule tied to milestones. Avoid paying 100% upfront—that's developer-friendly but leaves you unprotected if they disappear. A 20/20/30/30 split is standard, or negotiate based on project size and developer reputation.
Specify your payment method, invoice timeline (net 15 or net 30 days), and any late fees. Include a dispute resolution process: do disagreements go to arbitration, mediation, or court? Arbitration is cheaper and faster for smaller contracts but limits your appeal options.
Technical Support and Maintenance
Clarify post-launch support: Are bug fixes included for 30 days after delivery? What about patches for platform updates (iOS 18, Android 15)? Many developers charge maintenance fees ($500–$2,000/month) for ongoing support after the initial project ends.
Using a platform like Mercoly, you can compare game development providers, review their contract templates, and find studios experienced in your specific niche—whether that's indie puzzle games, VR experiences, or mobile multiplayer titles.
Frequently Asked Questions
Q: How much should I budget for a typical indie game? Indie mobile games range from $15,000–$50,000; mid-scale 3D games run $100,000–$300,000+. Budget depends on platform, art quality, team size, and timeline.
Q: Who keeps the source code after launch? You should own the final game and custom assets. The developer may retain proprietary code or libraries, but your game code stays yours—this must be explicit in the contract.
Q: What happens if the developer misses deadlines? Include a clear change request process and realistic timelines with buffers. Most indie contracts allow schedule adjustments without penalty if scope changes or technical challenges emerge.
