Golyamoto byagstvo

Golyamoto byagstvo (Голямото бягство; lit. The big escape) is a Bulgarian reality competition based on Matt Keane's Deathtrap.

Format
Casting calls are announced online, where prospective contestants submit audition tapes in hopes of being cast. All contestants selected must be between the ages of 16 and 21 at the time of taping.

Mini challenge
In the mini challenge, each contestant is asked to perform a different task with varying requirements and time limitations. Certain mini challenges are repeated from season to season. For instance, the first mini challenge of the first season is what appears to look like an oversize board game. Another recurring mini challenge is dedicated to a cross between Parcheesi and rock-paper-scissors. The winner of a mini challenge is sometimes rewarded with some kind of advantage in the main challenge. Though most episodes have a mini challenge, select episodes do not and progress straight to the main challenge.

Main challenge
The requirements of the main challenge vary across each episode, and can be individual or group challenges, and initially grant immunity to the winner in the next challenge. The winner of the main challenge also receives a "special" prize for their win. In the past, challenge winners have been rewarded with prizes including vacations and pieces of wood with certain patterns. The final main challenge of every season is where the contestants star in a mini-movie.

The goal of each maxi challenge involves a new theme and outcome. Contestants are often asked to design blueprints for inventions, sometimes incorporating unconventional materials. Other challenges focus on the contestants' ability to present themselves, perform with background music, or perform humorously. Some challenges become a tradition across seasons, such as the Lemon Touch.
