Comedy gameshow, where celebrity secret agents prank unsuspecting contestants to win them a cash prize.
In Koso Koso, contestants think they are in a reality show, unaware of the secret squad of celebrity agents constantly observing their every move! These undercover agents must skilfully complete ridiculous missions without arousing suspicion to win cash for the clueless contestants. With missions such as "Supermarket Sneak," where agents must hit targets on players' backs while they casually browse the shopping aisles, to the iconic "Night Mission," where they must execute tasks without waking sleeping contestants, the suspense and laughter are guaranteed. Once the missions conclude, the biggest secret is revealed: contestants find out about the gameshow they never knew they were playing and face a final challenge to win the cash prize.
With laugh-out-loud missions and big secret reveals, the surreal and instantly shareable content defines this unique, family gameshow with a twist.
