# Who Is the Millionaire

Ai là triệu phú (lit. 'Who Is the Millionaire') is a Vietnamese game show based on the original British format of Who Wants to Be a Millionaire?. The show was hosted by Lại Văn Sâm from its debut until 2017, Phan Đăng from 2018 to 2020, and Đinh Tiến Dũng from 2021 onward. The main goal of the game is to win the top prize (currently 250,000,000₫ from 2022) by answering 15 multiple-choice questions correctly. There are four lifelines – 50:50, Phone a Friend, Plus One (first appeared in 2020) and Ask Two Experts (can be used after the fifth question, first appeared in 2020). Ai là triệu phú? began broadcasting on January 4, 2005.
It is shown on the Vietnamese TV station VTV3 on every Tuesday at 9:00 PM (UTC+7).

## Ai là triệu phú - Ghế nóng

On 7 September 2010, an alternative version for regular Ai là triệu phú was aired, named Ai là triệu phú - Ghế nóng (lit. 'Who Is the Millionaire - Hot Seat'). This is a Vietnamese adaptation of the Australian game show Millionaire Hot Seat, with the game's rules being the same as the original Australian version (from 2009 to 2016). However, the show returned to its original format on 5 July 2011 after receiving feedback from viewers.

## Graphics

At first, Ai là triệu phú had a black interface similar to the most international versions, with a smaller question lozenge. From May 2008, the show switched to the modern blue Rave graphic based on the Australian version. When Ai là triệu phú returned from July 2011, the show used the Norwegian graphic with Arial font.
From June 2013: The question lozenge was smaller due to VTV3 switching to a widescreen format. Previously, in Hot Seat version, the question lozenge was also smaller, even though VTV3 was still using a standard screen format. At the end of 2014, Ai là triệu phú switched to a new, more beautiful and easier-to-see blue Rave graphic, inspired by the 2010 purple flux graphic in the UK version.
In 2021, the show switched to a brand new graphic, inspired by the design of Olga van den Brandt (Netherlands version) and the 2018 revival of UK version (question lozenge and Phone-a-Friend clock). The question lozenge was expanded to full screen.

### Filming locations

For the first episodes, Ai là triệu phú was filmed at the Gia Lam Gymnasium, Hanoi. The show then moved to S10 studio in mid-2005, and finally to S16 studio of Vietnam Television.
