What game UI/UX work requires

Game UI is not a flat design exercise. The interface has to hold up under gameplay pressure, render within the project's frame budget, and integrate cleanly into the engine's UI system. Game-Ace designers work on production projects in Unity and Unreal Engine daily, so wireframing, visual design, and engine handover are scoped together. This avoids the common pattern where final UI assets need to be rebuilt during integration because the import settings or prefab structure were not planned.

Engagement models for UI/UX projects

Clients hire a single UI designer to extend an in-house team, or assemble a UI/UX pod covering research, wireframing, visual design, and engine handover under one engagement. Engagements run as dedicated monthly hires with direct integration into the client's design and engineering pipelines from the first sprint. NDA and IP transfer are signed before any access to design assets or engine projects in development. Pipeline integration is reviewed during onboarding to align on tooling.

Why choose Game-Ace for game UI/UX

Game-Ace UI/UX designers deliver interface work that integrates into the engine without rebuild loops at handover.

  1. Engine-ready handover. UI assets are delivered with documented import settings and prefab structures for Unity UGUI, UI Toolkit, or Unreal UMG, not as flat exports.
  2. iGaming and casino UI experience. We have produced slot, casino lobby, and operator dashboard UI across regulated markets, with regulatory readability built into the design.
  3. Cross-platform coverage. Mobile, PC, console, and VR UI patterns are designed and tested from the same studio under one engagement.
  4. Research-driven design. Wireframes and visual design are grounded in documented player research and competitor analysis rather than assumed patterns.
  5. NDA and full IP transfer. Design source files, UI kits, prototypes, and documentation transfer to the client. NDA is signed before any review of in-development work.
Benefits of Game UI/UX Design

Cost of game UI/UX design

A focused UI design pass for a single mobile or PC title at Game-Ace starts from €15,000 covering wireframes and a core UI kit. Full UI/UX engagements with research, prototyping, and engine handover usually fall in the €30,000–€100,000+ range. Pricing depends on scope, platform count, and integration depth.

Our game UI/UX design process

1.
Discovery and research

Player research, competitor review, and platform constraints are documented. Output is a design brief that defines the interface direction and success criteria.

2.
Wireframing

Low-fidelity wireframes establish layout, navigation, and state flow. Wireframes are reviewed with the client gameplay and product team before visual design begins.

3.
Interactive prototype

Clickable prototypes validate flow and interaction patterns on the target platform. Findings feed adjustments before final visual design is committed.

4.
Visual design

Full UI kit production with documented states, hover behaviour, animation specifications, and accessibility considerations agreed with the client.

5.
Engine handover

UI assets are exported with documented import settings and prefab structures for Unity or Unreal Engine. Integration review with the client tech lead catches issues early.

6.
Post-launch iteration

Recurring sprints handle UI updates for live content, A/B test variants, and adjustments based on player metrics from the launched product.

Each milestone is reviewed against the design brief and engine constraints.

Game UI/UX design deliverables

Game UI/UX design deliverables

Game-Ace prepares a complete UI/UX design package with wireframes, source files, style guide, interactive prototypes, and engine-ready assets transferred at project close.

  1. Research and brief documentation. Player research notes, competitor review, and the design brief that drives wireframing and visual design.
  2. Wireframes and interactive prototype. Low-fidelity wireframes and a clickable prototype validated on the target platform.
  3. Full UI kit source files. Figma, XD, or Sketch source files with documented states, hover behaviour, and animation specifications.
  4. Engine-ready UI assets. Exported sprites, atlas configurations, and prefab structures for Unity UGUI, UI Toolkit, or Unreal UMG.
  5. Style guide and handover documentation. Visual style guide, font and colour tokens, and integration notes for the in-house engineering team.
  6. Post-launch support window. Agreed support period for UI updates and adjustments after release.

Game-Ace’s support was integral to the success of this project. Without them, the client wouldn’t have been able to complete the work on time.

They were responsive and their work was high quality – the client rarely had to share constructive criticism.

Game UI/UX design FAQ

Single-title UI passes for mobile or PC typically take 6 to 10 weeks. Full UI/UX engagements with research, prototyping, and engine handover usually run 12 to 24 weeks. Delivery time depends on scope, platform count, and the number of review cycles with the client product team.

Game-Ace supports Unity UGUI, Unity UI Toolkit, and Unreal UMG with engine choice set by the client. Asset export, atlas packing, and prefab structure are configured for the target framework so the UI integrates without rework on the engineering side. The engine setup is reviewed during onboarding, with sample import validated against the client's actual project before final deliverables are scheduled.

iGaming UI is a core capability. Output covers slot client UI, casino lobby design, bonus round interfaces, and operator dashboards. Designs are built for regulatory readability requirements and tested on the target mobile and desktop device matrix.

Validation is built into the process at multiple stages:
  • Wireframes are reviewed with the client gameplay and product team.
  • Interactive prototypes are tested on the target platform.
  • Player research findings are documented and fed into design adjustments.
  • Visual design is reviewed against engine constraints before final production.
This avoids late-stage rework caused by flow or technical issues being caught only during integration.

UI assets are exported with documented import settings and prefab structures so the in-house engineering team can integrate without conversion work. Integration review with the client tech lead is the final step before handover.

Spatial UI patterns are designed for Meta Quest, Pico, and PC VR headsets. Interaction layers cover hand tracking, controller input, and comfort patterns appropriate to the session length and trainee profile when the build is a training simulator.

Design source files, UI kits, prototypes, and documentation produced during the engagement transfer to the client at project close. NDA and IP transfer are signed before any review of in-development work, and no source material is retained by Game-Ace after handover.
