Coinzus

A bold, next-generation sweepstakes casino, designed end to end

Coinz.us is a bold, next-generation sweepstakes casino platform built for the competitive US market. The client came to ClefDev to develop a full-scale design and branding system from a blank page and to position the product as a top-tier sweepstakes brand – with four goals up front: a distinctive brand identity, higher user conversion and retention, a seamless purchase experience, and visual consistency across every platform.

We approached it as a multi-platform sweepstakes product, designing a unified experience across web, desktop, mobile and a Telegram Mini App. A vivid purple-and-gold identity, custom 3D illustrations and a clear coin-store and rewards flow give the casino real personality while keeping browsing and purchasing effortless.

The engagement covered the complete brand identity system – palette, typography and motion – a responsive product UI with optimized game browsing and rewards flows, the Telegram Mini App interface, and animated marketing creatives for paid ads and social media, delivered production-ready.

Stand out in a crowded US sweepstakes market – on every screen

The US sweepstakes casino space is crowded, and most platforms blur together: similar lobbies, similar coin stores, no real personality. Coinz.us needed a full-scale design and branding system that would make the product instantly recognizable and premium, while lifting conversion and keeping players coming back.

The second half of the challenge was reach. The experience had to stay consistent and on-brand across a lot of touchpoints – web, desktop, mobile and a Telegram Mini App – with marketing creatives that carried the same identity into paid ads and social, so every surface felt like one product.

One brand system, carried across web, mobile and Telegram

We treated Coinz.us as a single multi-platform sweepstakes product rather than a set of separate screens. A distinctive brand identity came first – purple-and-gold palette, typography, custom 3D illustrations and motion – then a UI system that streamlines game browsing and rewards, and finally the marketing creatives that push the same look out to ads and social. Every surface, from web and desktop to mobile and the Telegram Mini App, was drawn from the same system.
