Kulna Nfuz Lleila: MBC’s Real-Time Second-Screen Game

MBC Group is the largest media company in the Middle East and North Africa, operating over 17 leading TV channels. For one of its prime-time shows, MBC commissioned “كلنا نفوز الليلة” (We All Win Tonight), a real-time second-screen app built by Eurisko.

Challenge

The challenge

The show’s format leans entirely on omnichannel play: questions appear on TV, and viewers answer on their phones. Answer 20 questions correctly and you enter the draw for valuable prizes; it is a level game where players climb until a wrong answer stops them, with coins available to continue.

That format means enormous, spiky, real-time load: hundreds of thousands of viewers answering the same question in the same seconds, with fairness and latency both non-negotiable.
