While "Vas o No Vas" has the same presentation style and look as the U.S. "Deal or No Deal", the gameplay is different from the US English-language version, and adopts variants of European and Australian versions of the game with a quiz contest to determine the player who goes on to play for the money.
First Round
The first round of the game involves two sets of ten potential contestants, in which they each answer a question with three possible answers on cell phones provided in a sponsorship deal by T-Mobile. The two contestants that answered correctly the quickest on each side proceed on stage to play the second round.
Second Round
In the second round, Sandarti asks a series of questions. The first contestant to answer two correctly proceeds to the main game. But first, model Silvia Bianchin, dressed in a red dress, walks on stage with a red case marked "Tentación". The "Tentación" case, which contains cash, a Ford automobile in another sponsor placement, or another prize, is offered to the contestant. The contestant may refuse the Tentación offer and continue to the main game, or accept the offer and allow the losing contestant to play the main game.
Main Round
The main round is the same as the US English version, with 26 similarly dressed models carrying 26 cases. The number of cases to be opened in each round is also the same, starting with six cases in round one, then five in round two, and so on, all the way down to one case in round six and subsequent rounds. The top prize in this version, however, is US $250,000. If the player can keep the top prize amount in play after three rounds, they win a Ford automobile which is theirs to keep no matter what happens in the main game. After each round, as in the English version, the banker calls the host. However, the offer is announced after the banker's female assistant comes on stage with a case containing the offer that the banker offers the contestant. For example, if the banker is offering $3,200, then she will say, "La Banca te ofrece,... tres mil doscientos dolares." In addition, in some offers, the "Tentación" case would also be brought on stage as a further enticement. The "Tentación" is shown before the contestant decides to accept the offer and leave the game, or refuse the offer and continue. At the conclusion of the first round, a guessing game similar to the Australian version's "Megaguess" called "La Coincidencia" is played, in which the loser of the head-to-head game can win a prize by guessing what amount is in the case chosen by the contestant. The highest amount ever won was $180,500 on November 5, 2006 by a contestant named Gabriela Salazar from San Diego, CA, although another contestant would sell the $250,000 case for only $44,300 the following week. The contestant also won a Ford F-150, boosting her total to over $200,000, an all-time record for a Hispanic-language game show telecast in the USA. Her case chosen had $100,000 inside.
Lucky Case Game
The at-home "Lucky Case Game" was the same as the English version, except that the prize is doubled to $15,000.
