On July 25, 2011, Maria del Carmen Bonilla from Asturias won €300,000 and became the second top prize winner.

At various points in the game, La Banca (The Banker) makes a phone call to the host and makes the contestant a cash offer to purchase their box and for the contestant to quit the game based on the value of the boxes left.

In 2005, the show started a phone-in feature where the in-studio contestant would split their winnings with a lucky at-home caller.

The show was revived in 2011 on Telecinco's sister network Cuatro, with the original board and a new twist—the Green Boxes.

The first season of the 2023 revival aired on Sunday nights as a weekly prime time format with a runtime similar to that of the 2006 million-euro specials.

NOTE: In each episode, three of the smaller values are replaced with three different joke prizes (except for the million euro specials).
