An iGamity Talk with Marv Riley, Art Director & Senior UI/UX Designer
In casino gaming, great design often goes unnoticed. Players don't think about UI layouts, symbol hierarchy, or reel speeds. They simply enjoy the experience. But behind every smooth interaction lies a series of thoughtful design decisions that guide attention, build anticipation, and keep players engaged without overwhelming them.
For Marv Riley, Art Director and Senior UI/UX Designer with years of experience across mobile games, LiveOps, and iGaming, successful slot design isn't about adding more features. It's about removing friction and making every interaction feel effortless.
In this edition of iGamity Talks, Marv shares his perspective on player-first design, leadership, production workflows, and why simplicity remains one of the most powerful tools in game development.
The Best Slot Game UI Is the One Players Hardly Notice
When players launch a slot game for the first time, they begin processing information almost instantly.
Before they understand mechanics or bonus features, they need to understand what matters on the screen.
According to Marv, that journey starts with the symbol set.
A clear visual hierarchy helps players immediately distinguish premium symbols from lower-value ones. Every symbol should be easy to recognize, visually distinct, and designed to support quick decision-making during gameplay. Olga Ryzhkova interview
Even reel speed plays an important role.
If reels spin too quickly, players struggle to follow important symbols. Too slowly, and the excitement disappears. Finding the right balance allows players to naturally track winning combinations while maintaining anticipation.
Marv also highlights subtle visual techniques, such as keeping lower-value symbols within a unified color family. This creates natural visual gaps that allow premium symbols and bonus icons to stand out more clearly during spins.
Good UI design doesn't compete for attention. It directs attention.
Keep It Simple. Keep It Exciting.
Modern slot games continue introducing new mechanics and bonus features, but Marv believes complexity should never become the goal.
Many of the industry's most successful games succeed because players understand them immediately.
Simple gameplay allows players to focus on excitement rather than learning complicated systems.
Instead of layering endless mechanics onto a game, Marv advocates for a straightforward structure built around a strong base game, meaningful bonus features, and well-designed jackpots.
Early player engagement is equally important.
Within the first few minutes, players should experience a satisfying win, feel the anticipation of a bonus feature, and understand what they're working toward. These carefully timed moments build emotional investment and encourage continued play.
For Marv, one principle consistently applies.
Keep it simple.
Designing Interfaces That Stay Out of the Way
Unlike many other game genres, slot games revolve around a single focal point: the reels.
Everything else should support that experience rather than compete with it.
Marv believes interface elements should interfere with gameplay as little as possible. Whenever practical, menus, jackpot displays, and secondary information should remain hidden until players choose to access them.
Sliding panels and contextual UI create cleaner interfaces than large pop-up windows that block symbols or interrupt gameplay.
Even elements like win meters don't need to occupy permanent screen space. Displaying them only when relevant keeps the interface uncluttered while allowing players to stay focused on the game itself.
The philosophy is simple.

Research Before Reinvention
Unlike mobile applications, where frequent A/B testing guides design decisions, iGaming presents unique challenges due to regulatory approvals and jurisdictional requirements.
Because of this, Marv encourages designers to study existing successful games before beginning new projects.
Rather than reinventing familiar mechanics, teams should analyze games with similar features, understand what works, identify common design patterns, and use those insights to inform their own solutions.
Wireframes, layout exploration, and usability discussions become essential parts of this process.
Innovation remains important, but it should always begin with a strong understanding of proven player behavior.
Leadership Is Built on Trust
While design skills are essential, Marv believes leadership plays an equally important role in successful production.
One of the strongest foundations for any creative team is trust.
When stakeholders trust an Art Director's vision, communication remains focused, feedback stays organized, and artists can concentrate on creating great work without conflicting instructions from multiple directions.
The Art Director becomes the single point of communication between leadership and production, ensuring feedback is consistent and project goals remain clear.
Without that structure, production timelines become longer, revisions multiply, and teams lose focus.
For Marv, creative leadership isn't about controlling every decision.
It's about creating an environment where artists always know who to turn to and where projects move forward with confidence. Harnain Singh interview, "Creativity Thrives on Strong Planning"
Better Processes Create Better Teams
Beyond creative direction, Marv places enormous value on transparency and documentation.
Throughout his career, he has relied on collaborative visual workspaces such as digital whiteboards to organize mood boards, concept exploration, design iterations, and production tracking.
These shared spaces provide visibility across entire teams while making it easier for leadership to review progress without interrupting artists during production.
Equally important is documentation.
Marv believes every project should be documented so thoroughly that someone unfamiliar with the game could immediately understand how and why it was built.
Effective documentation goes beyond listing completed assets.
It explains the reasoning behind creative decisions, production standards, workflows, and implementation guidelines.
Strong documentation accelerates onboarding, improves consistency, and preserves valuable knowledge long after projects are completed.
Building a Stronger Creative Community
Reflecting on the industry's future, Marv sees tremendous value in open knowledge sharing.
Many lessons learned throughout a creative career come through years of experimentation or remain confined within individual studios.
By bringing experienced professionals together, platforms like iGamity help make those lessons accessible to a much broader audience.
Every artist approaches game creation differently. Some prioritize visual storytelling, others focus on mathematics, player psychology, production workflows, or technical execution.
Sharing these diverse perspectives strengthens the industry as a whole and helps emerging creatives develop a more complete understanding of game development. iGamity Talks hub
Final Thoughts
Marv Riley's approach to design reminds us that the most successful slot games are rarely the most complicated.
They are the ones that communicate clearly, respect the player's attention, and create excitement through thoughtful design rather than unnecessary complexity.
From symbol hierarchy and UI layouts to leadership, documentation, and production processes, every decision contributes to a seamless player experience.
As the iGaming industry continues to evolve, designers who embrace clarity, collaboration, and player-first thinking will create experiences that feel intuitive, engaging, and memorable.
Sometimes the best design isn't the one players notice most. It's the one that lets them simply enjoy the game.
