I’m building a real-money casino platform that centres on a single, fast-paced “Colour Game – Big & Small” and I need a hands-on technical partner to turn the idea into a fully-functioning web + mobile app. The app must feel modern and sleek from the first tap, scale to thousands of concurrent players, and meet the regulatory and security standards expected of any serious betting product. You’ll take charge of the full product cycle: wireframing, UI/UX, front-end development, back-end architecture, payment and KYC integration, random-number logic, and an admin dashboard for live odds and user management. I can provide the game rules, house-edge settings, and growth roadmap; you bring the know-how to ship a rock-solid, revenue-ready release and iterate quickly as we scale. Core deliverables • Responsive web and iOS/Android builds using a modern stack of your choice • Provably fair RNG for the Colour Game – Big & Small variant • Secure wallet, deposits, withdrawals, and promo code system • Real-time game engine with leaderboard and chat • Admin panel for game parameters, player analytics, and risk controls Acceptance criteria 1. UI matches approved modern-sleek mock-ups across all devices. 2. Game rounds resolve in ≤2 seconds with verifiable randomness. 3. Payments pass sandbox tests for at least two major gateways. 4. Full source code, deployment scripts, and documentation are handed over. If you’ve launched casino, sportsbook, or similar betting apps before and are ready to co-own the next million-dollar hit, let’s discuss how we can split responsibilities and profits.
