Ai Là Triệu Phú

Ai Là Triệu Phú is the Vietnamese version of Who Wants to Be a Millionaire? which premiered on January 4, 2005 on VTV3. The main goal of the show is to win 150,000,000₫ (about $6,585) by answering 15 multiple choice questions correctly (the previous top prizes were 50,000,000₫, 100,000,000₫ and 120,000,000₫). The show is broadcast on VTV3 every Tuesday at 20:30 (earlier 20:00 and 20:05) and a repeat at 9.20 am on Wednesday.

The show was hosted by Lại Văn Sâm from January 4, 2005 to December 26, 2017. He left the show after his retirement at age 60. After the last episode featuring him as the host was broadcast on VTV3, there was a selection of who would become the new host. At the end of the selection, Phan Đăng was chosen to take over the role as the new host of the show from 2018 afterwards.

Filming
The show filming takes place in the studio of Vietnam Television Station (VTV) in Giảng Võ, Hanoi, Vietnam.

Rules - Effective from January 2, 2018
A contestant was asked a series of up to 15 from easy to difficult, time is not limited. Questions 5 and 10 were known as milestone questions, if they were to be answered correctly, they would increase the contestant's minimum payout to the cash value they had attached. This would continue until either the contestant answered all 15 questions correctly, miss a question or decide to walk away with all of the money they had received thus far. Any of these conditions being met marked the end of a contestant's game.

After viewing a question, the contestant can walk away or continue. If they walk away, they will leave with the money already won rather than attempting an answer. If the contestant answers a question incorrectly, the game ends and all of their winnings are lost, except that the ₫2,000,000 and ₫22,000,000 prizes are guaranteed. A contestant could leave empty handed if they provide a wrong answer to any of the first five questions. By correctly answering all 15 questions, the player becomes a "millionaire".

After the previous contestant finishes the game, the host will invites the next contestant until the end of the program. If the player has not finished the game but time is up, the player will be able to continue in the next episode.

Lifelines
There are four lifelines:
 * 50:50 (Năm mươi - Năm mươi)
 * Phone-A-Friend (Gọi điện thoại cho người thân)
 * Ask the Audience (Xin ý kiến khán giả trường quay, previously "Hỏi ý kiến khán giả trong trường quay")
 * Three of the Audience (Hỏi ý kiến của tổ tư vấn trường quay, previously "Tư vấn tại chỗ"). When this lifeline is picked, three people in the audience are randomly selected by the contestant for assistance, and they suggest the contestant the answer they think is correct. Can be used after answering the ₫2,000,000 question (5th question) correctly. A total prize fund of 600,000₫ is shared equally for each correct answer (in some cases, all three people gave a wrong answer. As a result, no one won any money)

Special episodes
The producers of the show usually celebrate holidays in Vietnam by producing episodes with specific contestants that the producers invite to join the show (i.e. On the International Day of Older Persons episode, the show will invite contestants whose age is at least 50). Celebrity contestants may also appear on major holidays (such as Lunar New Year, Valentine's Day and International Women's Day) and they are allowed to keep their winnings or donate them to their charity of choice.
