Sweepstakes casino and sports betting platform for US market
CHALLENGE
To stand out in the competitive US sweepstakes casino market, COINZ.US needed a visually compelling and conversion-optimized design that appealed to both casual and returning players. The goal was to build a seamless digital experience that integrates modern UI trends, supports mobile-first gameplay, and offers deep branding flexibility — all while complying with sweepstakes regulations.
Approach
I began by analyzing leading sweepstakes casinos in the US to uncover design gaps and opportunities to innovate. I identified the importance of clear incentives, trust-building UI elements, and user onboarding tailored to US audience expectations.
I crafted a dual light and dark theme design system to suit different player preferences and maximize accessibility across devices. These themes were built to be easily switchable, fully responsive, and visually coherent — ideal for late-night players or daytime users alike.
To extend platform accessibility, I also designed a Telegram mini-app layout for COINZ.US, ensuring players could check balances, claim rewards, and participate in promotions directly from their favorite messaging app.
Solution
The final delivery was a fully responsive, branded UI/UX system for COINZ.US that includes:
A bold, modern sweepstakes casino design tailored for the US market
Custom light and dark mode support for enhanced user personalization
Streamlined navigation and fast-loading mobile-first layouts
A fully integrated Telegram mini-app design to boost re-engagement and user acquisition
UX flows optimized for sweepstakes registration, daily bonus claims, and virtual coin purchases
This project demonstrates our expertise in designing for sweepstakes casinos, blending regulatory awareness with high-performing UX. The COINZ.US platform is now primed for rapid launch, improved retention, and scalable growth within the evolving iGaming and sweepstakes ecosystem in the United States.
