Tko želi biti milijunaš?

Tko želi biti milijunaš? (English translation: Who wants to be a millionaire?, usually called Milijunaš) is a Croatian game show based on the original British format of Who Wants to Be a Millionaire?. The show is hosted by Tarik Filipović. The main goal of the game is to win the top prize (1 million kn from 2002 to 2022, €150,000 as of January 5, 2023) by answering 15 multiple-choice questions correctly. There are 4 "lifelines", which are ways for a player to get help during the game. They are 50:50 (pola-pola) (2002–present), phone a friend (zovi) (2002–present), ask the audience (pitaj publiku) (2002–2020, 2022–) and an additional lifeline three wise men (tri znalca) (2020–2022). The game show was broadcast from 2002 to 2010 and from 2019 onward. It was shown on the Croatian TV station HRT1. From 2002 to 2022, when a contestant got the fifth question correct, he left with at least 1,000 kn. When a contestant got the tenth question correct, he left with at least 32,000 kn. As of January 5, 2023, When a contestant got the fifth question correct, he left with at least €150. When a contestant got the tenth question correct, he left with at least €5,000.

The show airs on Thursdays in the television primetime. The 2019 revival underdid minor changes to the show, but there were no bigger changes to the quiz format itself. The "zovi" lifeline was shortened down to 25 seconds from 30, due to increased availability and faster speed of internet search engines, such as Google. The choice of contestants for "najbrži prst" was cut down to 6 contestants from original 10. An additional lifeline "tri znalca" (three wise men) was added in 2020 to substitute "pitaj publiku" (ask the audience) for the rest of the season due to coronavirus situation.

This version is also the second country to adapt the new International Rave graphics which were created by Olga Van Den Brandt.
