GeoClash.

Geography quizzes are mostly solo quiz screens that get dull after a few rounds and give players no reason to return the next day. Our goal was to turn flag and capital questions into a game raced live against friends and rivals around the world: a fair, lag-free duel engine where both players see the same questions at the same moment, a progression loop that brings players back daily — all at the same quality on two platforms and in 10 languages.

We built the iOS app natively in SwiftUI and the Android app in React Native, both connected to the same Node.js backend. There are three game modes: self-paced Practice, Challenge a Friend where an invited friend races on the same questions, and real-time Online Multiplayer matchmaking. Boosters (50/50, Extra Time, Skip, Hint), a heart system and a coin economy add strategy to every question; daily streak rewards, levels/XP, badges and weekly & monthly leaderboards (global, friends, country) keep players coming back. Questions are served from the cloud, with content and game settings managed from a custom Next.js admin panel. Revenue runs on in-app coin packs and rewarded ads; the interface ships in a glossy arcade design language with its own mascots.
