The Idea

In 2021, I noticed a growing problem in our country’s gaming community.
Gamers were passionate — but stuck.

Because of political and financial restrictions, players couldn’t easily purchase in-game items, recharge accounts, or buy premium passes for popular titles like Call of Duty: Mobile, PUBG, Free Fire, and Apex Legends.

The result?
Thousands of skilled players felt locked out of the full experience — unable to compete, upgrade, or express themselves like their global peers.

So, together with a friend, I decided to build DominoGem — a platform that would give gamers:

  • A safe, fast, and reliable way to buy in-game credits and premium items.
  • A simple, transparent, and trust-based experience in a market full of uncertainty.

We wanted to build not just a shop — but a community hub for players.




From Vision to Product


Finding the Opportunity

I began with market and competitor research, studying dozens of regional platforms offering similar services.
Patterns emerged quickly:

  • Most platforms had cluttered UIs with too many steps.
  • Checkout flows were confusing and often failed during payment.
  • None created a brand gamers could actually love — they were purely transactional.

This gave us our direction:

“Make DominoGem feel like a gamer’s space — fast, fun, and trustworthy.”


Defining the Brand

I designed the visual identity and logo, drawing inspiration from gaming badges and modern esports minimalism.
We wanted DominoGem to look cool but credible — the kind of site a gamer could trust at first glance.

We also decided to add personality through dynamic colors, light/dark modes, and micro-interactions inspired by loot-box reveals.




Designing the Experience

The product had three main pillars:

  1. Speed — every action should take seconds, not minutes.
  2. Trust — transparent pricing, visible order history, and secure payments.
  3. Excitement — gamification to make even a top-up feel rewarding.


The Core Flow

I designed a lightweight and frictionless purchase flow:

  • Choose your game → Enter player ID → Select credit amount → Confirm → Pay.
    No registration walls, no waiting screens — just pure function.

We optimized for mobile from the start, using progressive loading and short micro-steps to reduce friction.


Building the Ecosystem

As the user base grew, I expanded the platform with features that deepened engagement:

  • User Club: a loyalty system where players earned XP and ranks for every purchase.
  • Wheel of Fortune: a gamified experience where users could win discounts or bonus credits.
  • Referral & Reward System: encouraging viral growth among friend groups.
  • Personal Dashboard: order history, saved payment methods, and dynamic offers tailored by behavior.

Each new feature was tested with small player groups to refine UX balance between reward and simplicity.

Growth & Impact

We launched quietly — with minimal ad spend and no paid influencers at first.
Instead, we focused on authentic community marketing:

  • Collaborated with popular local streamers and esports figures for gameplay videos and product mentions.
  • Released short motion ads targeting gaming sub-communities.
  • Implemented smart web advertising, retargeting based on abandoned carts and most-viewed games.

Within the first month, DominoGem reached:

  • 1,000+ registered users
  • 500 successful transactions
  • 30% conversion rate — unusually high for a new B2C fintech-gaming product.

As we scaled, engagement rose sharply thanks to the User Club and Wheel of Fortune, which increased:

  • User retention by 40%
  • In-app purchases by 25%

These results proved that our early UX and brand investments created not just customers — but a loyal player base.





Collaboration & Execution

As Co-Founder and Product Designer, my role extended far beyond wireframes.
I managed:

  • Design & Development alignment, ensuring we shipped fast without losing consistency.
  • Support operations, helping users resolve issues during early beta stages.
  • Marketing collaboration, defining tone and messaging for social ads and influencer partnerships.

We grew from a 2-person team to a cross-functional crew covering design, engineering, and support — all united under one mission: make the gaming economy accessible.




Reflection

DominoGem wasn’t just a startup — it was a lesson in how trust, speed, and emotion drive user behavior in digital commerce.

We entered a saturated market, but we won by making people feel safe, excited, and seen.

“Great design doesn’t only simplify payments — it builds confidence in every tap.”


Building DominoGem taught me how to combine design strategy, business thinking, and community growth — skills that shaped how I approach every product since.
