This is followed by a "phone call" by "The Banker", a mysterious figure whose face is not shown (at times a silhouette can be seen).

He purportedly sits in a skybox (situated between the two audience sections) and makes an offer, via telephone to the host (his voice is never heard) to buy the contestant's case, loosely based on the mean of the cash amounts still in play, and also based on the player's psychology.

As the field of briefcases dwindles, one or more of the supporters are asked to consult with the contestant and help them make a decision.

These exchanges have become emotional, particularly when very high and very small amounts remained and the Banker offers a large cash buyout.

Players who say Deal to the Banker's offer are often given the chance to play out the game entirely at no risk to them to see if they had made the right choice in accepting.

Contestants who joined through text messaging are selected and screened with a series of interviews and tests, including a psychological one, before they appear on the show.

For the very first time in this season and for this franchise, celebrities were the ones to hold the briefcases and a roulette was used to determine who among the 20 Lucky Stars would be the player of the day.

Since the celebrity player of the day is also part of the 20 Lucky Stars, so after each star's situated briefcase is opened, they would sit in the audience space provided with a special platform row and would help the player in case if he/she has a difficult time during case selection at gameplay, thus eliminating the supporters' area of the studio.

The currency of the amounts on the money board, on the briefcases, and offered by the Banker to the contestants is in Philippine pesos.

Throughout the show, the peso sign is never used in all of the amounts on the money board, on the briefcases, and offers by the Banker to the contestants.

But later in the third season, the one highest value was replaced with ₱1,000,000 each, similar to the Million Dollar Missions of the American version.

On January 5, 2009, the case values for the ₱4M Edition were brought back into play at par with the new year.

The first three seasons featured the 26K girls, which unlike the U.S. counterpart, can handle any case per episode instead of being placed in a permanent position.

Participants have included Wendy Valdez, Diana Qeblawi Toni Alyessa Hipolito, Dang Palma, Bernice Tan, and Ferleene Noguera.

[9][10] In the fourth season, the show featured a new set of models known as the 24K alluding to the number of cases played per game.

The fifth season introduced celebrities as case models, known as the "20 Lucky Stars," a first in the franchise's history.

Since the celebrities did not choose their initial cases, they were given the option to either swap for another briefcase or keep their assigned one until the end of the game.

On July 10, 2006, a text-messaging game was introduced as a new segment of the show for the viewers to participate and win cash prizes.

Along with the show's return, a new promo was launched, named after the first text promo Ka-text, Deal or No Deal, wherein home viewers could win half of either what the contestant has won or the contents of the chosen briefcase (i.e. ranging from ₱0.50 to ₱1,500,000).

In a third promotion, this time using the show's title, viewers were invited to guess which briefcase contained ₱3,000,000.

Prior to the start of the 4 million Edition, a commercial of the show was released where barangay captains were invited to join and play as studio contestants.

On November 30 to December 1, 2007, the show finally made its first out-studio episodes at the parking lot of SM City Cebu.

The episode was conducted in a similar manner to the U.S. version of the format, featuring an American contestant and prizes in U.S. dollars.

[20][21] ABS-CBN's PR campaign for that event also earned the show a Philippine Quill Award of Merit in the same year.
