The show challenges celebrities (singers and actors) to perform as different iconic music artists every week, which are chosen by the show's "Randomiser". They are then judged by the panel of celebrity judges including Goran Navojec, Sandra Bagarić and Tomo in der Mühlen. Every week, one celebrity guest judge joins Goran, Sandra and Tomo to make up the complete judging panel. In the Final of the fourth season, Sandra didn't vote, so there were two guest members of the jury - Indira Levak and Mario Petreković. Each celebrity gets transformed into a different singer every week, and performs an iconic song and dance routine well known by that particular singer. The Randomiser can choose any older or younger artist available in the machine, even a singer of the opposite sex, or a deceased singer. In third season (Week 3), ability to use a joker was introduced. If celebrity wasn't happy with the Randomiser's output or thought that the task is too hard, they could ask some other celebrity to perform instead of them, but just once per season. It was announced that the show will get even more new content in the fourth season, but the 'Joker' ability was removed.[1] The new content in the fourth season was the introduction of holographic performances. If the "Randomiser" chooses a celebrity should perform a duet, they can do it using the pre-recorded hologram for one of the given singers. The winner of every episode gets to donate 10 000 HRK, while the overall leader gets to donate 40 000 HRK at the end of the season. The show lasts for 13 weeks.
Voting
The contestants are awarded points from the judges (and each other) based on their singing and dance routines. Judges award from 4 to 12 - excluding 11 - points to each contestant. After that, each contestant gives 5 points to a fellow contestant of their choice (known as "Bonus" points). In week 12 (semi-final week), four contestants with the highest number of votes will qualify to the final. In week 13 (grand final), previous points will be transformed into a 4-7 system, the jury will award from 8 to 12 points, and contestants will give 5 points to a fellow contestant of their choice.

Tomo in der Mühlen - German-born music producer and DJ based in New York City and Zagreb.
Goran Navojec - Croatian actor, known for many roles on television series and in feature films.
