Enabled scalable multiplayer gameplay aligned with short session lengths, Created a system flexible enough for future live-ops and events
This was a live multiplayer product for the Brazilian market, supporting sessions with up to 10 players.
The experience depended heavily on:
Real-time synchronization across players
Fast-paced decision cycles
Social dynamics like bluffing and risk-taking
Unlike single-player experiences, clarity and timing directly impacted both engagement and fairness.
I designed a round-state system that governed the full lifecycle of a match:
Defined clear phases for play, raise, and resolution
Structured turn progression to avoid ambiguity
Translated real-world bluffing mechanics into predictable interaction flows
This ensured that even in fast multiplayer sessions, players could understand and act without confusion.
I approached the problem as a systems design challenge rather than a visual one.
Instead of focusing on UI first, I structured the underlying gameplay logic to reduce ambiguity and support decision-making under pressure.
The goal was to make the system legible so players always understood:
What state the game is in
What actions are available
What the consequences of those actions are
A key issue was early drop-off in competitive modes.
Traditional elimination formats removed players too quickly, especially new users.
To address this, I designed a hybrid tournament system:
Allowed multiple losses to reduce early frustration
Introduced progression filtering to maintain competitiveness
Structured short match cycles (3–5 minutes) aligned with player behaviour
I also designed reward and leader board systems to encourage repeat participation and sustained engagement.
Several trade-offs shaped the system:
Clarity vs speed — ensuring players understood the game without slowing it down
Fairness vs competitiveness — balancing accessibility for new users with depth for experienced players
Engagement vs complexity — maintaining excitement without overwhelming users
These decisions required aligning game logic with user behaviour rather than adding more UI.
Designing for multiplayer introduced additional constraints:
Actions had to stay synchronized across all players
Network latency could affect timing and perception
Decisions needed to feel immediate, without breaking flow
I structured interactions to maintain consistency across players while keeping the experience responsive and intuitive.
Reduced early drop-offs by improving tournament accessibility
Maintained engagement across longer play sessions
Enabled scalable multiplayer gameplay aligned with short session lengths
Created a system flexible enough for future live-ops and events
More importantly, this project reinforced the importance of designing systems not just interfaces—when user behaviour depends on real-time decisions.
