Smrtelná past

Smrtelná past was a Czech-Slovak reality competition based on Matt Keane's Deathtrap.

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

Mini challenge
In the mini challenge, each contestant was asked to perform a different task with varying requirements and time limitations. Certain mini challenges were repeated from season to season. For instance, the first mini challenge of the season 1 was what appeared to look like an oversize board game. Another recurring mini challenge was dedicated to a cross between Parcheesi and rock-paper-scissors. The winner of a mini challenge was sometimes rewarded with some kind of advantage in the main challenge. Though most episodes had a mini challenge, select episodes didn't and progress straight to the main challenge.

Main challenge
The requirements of the main challenge varied across each episode, and were either individual or group challenges, and initially granted 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 was where the contestants star in a mini-movie.

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