Who Wants to Be the First? (Season 5)

 was the sixth season of Who Wants to Be the First?. Hosted by nam7ccaothang, listed by his real name Đặng Hoàng Nam. This would be the first season to use the ĐS currency, which stands for Đong Sofia the First. The trailer of the season was released on May 27, 2021 at 9pm (UTC+7), and premiered the next day after the trailer. This season was divided into two mini-seasons, labelled Season 6A and 6B. It was originally to have 17 episodes in total counting both two mini-seasons, but the 17th episode which was intended to air on September 6, 2021 has been postponed indefinitely citing the host unable to edit the video in time. Due to the channel surprisingly went on indefinite hiatus, the season was presumably ended on August 29, 2021 with 16 episodes.

In this season, the show's logo no longer contain the show's English name, although the show still uses the Season 5 logo in the first episode. The program also uses the Olga graphic of Vietnam in 2021. The interface of the question and the total prize has been added a few new animations, similar to few countries that are using this Olga version. This type of animation was firstly used in Who Wants to Be the First: Hot Seat (Season 3).

In fact, animation to the question and the total prize interface was already applied in Seasons 2 and 3, on that time when the program uses the PowerPoint software which was designed by Nguyễn Việt Anh, although the program later still used by the receiver. During Season 2, the program uses 2017 Rave from international versions, while during Season 3, the program uses the Rave U.S. 2020 pre-Olga, but this was dropped during the Gamblers Special since the show now had a new software suite made by STR Format. In this season, the program uses another new software based on the software that Ai là Triệu Phú - TV House used until now.

In the UEFA Champions League Edition episode, Olga van den Brandt's graphic identity was edited according to the UEFA Champions League tournament theme, except for the question interface that remains the same, similar to the Christmas Special and New Year Special episodes during Season 4.

The entire sound for this season is almost the same as in Season 5, except for the completely refreshed ending music. The traditional 15-question format also returned this season, for the first time since Season 1. The only different being the number of lifelines was increased to 4 and there is no longer the rule of reusing the lifelines.

A special edition called Second Chance Edition was introduced in the fourth episode of the season. Contestants who left empty-handed or having the least money in the past three episodes were invited for second chance. Contestants who were invited for the Second Chance Edition, were given a new lifeline, Ask the Host which replaced Power Paplu in the previous episode.

During this season, there is also another special edition called 1st Anniversary Special, to celebrate 1-year since the premiere of the show, on July 19, 2020. This was firstly teased when there was an unaired pilot with Đặng Hoàng Nam as contestant taped in early-July 2021. While the show uses the 16-question format, contestant can now adjust the second milestone, typically "safety net" in a high-risk format. This format was firstly used back in Season 4.

In addition to the main host, this season there were invited guest hosts, Nguyễn Ngọc Đức guest hosted the Second Chance Edition, the unaired pilot and the episodes 11, 14 and 15.

Trivia

 * On June 1, 2021, it was teased by the host that there are 9 new contestants in this season. The registrations for the show were conducted through Google Forms.
 * This was the first season to take place even though the current Hot Seat season has not ended, this was due to the UEFA Champions League Edition special must be broadcasted a day before the UEFA Champion League final matchup for the 2020-21 season, which involved Manchester City and Chelsea.
 * During the first episode:
 * In a rare occurrence, after Lã Minh Khánh's 8th question, the "Phone-a-Friend" lifeline in the money tree was crossed out although it was not used yet. This was fixed in a few seconds by duplicating a "Phone-a-Friend" lifeline graphic to cover the one that has been crossed out, however it was not fully covered as the crossed out graphic still can be seen behind. After Minh Khánh used the "Phone-a-Friend" lifeline on the 11th question and got it right, the duplicated graphic of the "Phone-a-Friend" lifeline was not removed for no apparent reason, nor being crossed out.
