Colour Champion — Cross-Platform Reflex Game

The result

A polished, free-to-play game live on both app stores with online multiplayer, ranking and a competition layer that drives repeat play.

The challenge

Colour Champion is a fast-paced colour-reaction game — easy to learn, hard to master — that tests focus and reflexes. The hard part is not the core loop; it is everything around it: low-latency real-time multiplayer and private rooms, fair matchmaking, global leaderboards, achievements and tournaments, all delivered smoothly on both iOS and Android from a single codebase.

How we built it

  1. 01

    Implemented the client-provided game design in Flutter (one codebase, iOS + Android)

  2. 02

    Built a serverless Firebase backend with real-time multiplayer over Firestore streams

  3. 03

    Created find-or-create matchmaking with graceful host reassignment and reconnection

  4. 04

    Added global leaderboards, achievements, social/guest auth and ad-supported monetization

  5. 05

    Shipped a dedicated marketing landing page for the game
