Devilbet
Making a platform for betting, shopping and fiat–crypto exchange feel as simple as playing one game.

Context
DevilBet is an online gaming platform that mixes classic betting with modern mechanics and its own virtual currency, DevilCoins. Players use them to play, to buy tech products in a dedicated shop, and to exchange freely with fiat and crypto.
Challenge
Three products in one: a casino, a shop and an exchange. Each brings its own flows, rules and vocabulary. The risk was an interface where players get lost between features instead of playing, and an MVP that could not grow without a redesign.
My role
As the Product Designer I owned the experience end to end: information architecture, user flows, UI for desktop and mobile, interaction design and the interactive prototype. I built a dedicated Design System and defined the colour palette as Tailwind tokens, so the build team could move fast and stay consistent.
Key decisions
Three pillars, one screen
Navigation on the left, the game at the centre, the community on the right. The sidebar stays visible for quick orientation and collapses behind the menu when players want to focus, so the game area is never crowded.
Live chat as an engagement loop
The chat is not support hidden in a corner. Wins, bonuses and messages flow in real time next to the game, turning a solo session into a social one and giving the platform a reason to come back.
DevilCoins as an ecosystem
One currency across games, shop and exchange, always visible in the header with a single “+” to top up. Players never switch mental model between playing, buying and trading.
Mobile with the same logic
On mobile the sidebar becomes a bottom bar and the chat opens as its own panel: same structure, same components, built for the thumb.

Outcome
A complete MVP ready for development: a platform that feels like one product instead of three, with a component library that scales to new games and features without redesigning the core.
