Supermarket made its debut February 24, 1992. Antena 3 recorded the program on a one thousand meter set simulating a supermarket located in a warehouse in the outskirts of Madrid.
As in its American counterpart, there are three teams and each team starts the game with an automatic one minute and thirty seconds (1:30). Players in this version follow the same format as the American version, as well. The Question Round is divided into three parts. In the first two parts, players answer questions about products found in the grocery store and the third part is the Round Robin. Each correct answer was worth 10 seconds. In games where all three players select the correct answer, 20 seconds is added to each team's clocks.
As the show aired every day, variety in the type of games played was a must. Because of this several games were played, but each generally utilized the following objectives:
- Selecting which of three products had a lower or greater than the amount indicated price.
- Selecting which of three products had the incorrect price.
- Selecting which of three products had the correct price.
- Selecting which of three products was the most expensive.
- Determining how much of each product you could buy with a certain sum of money.
- Determining if the current price of a product was higher or lower than the one showed.
- Determining if the price could also be correct.
The rules of the Big Sweep were the same. Players could only grab of any item and would be penalized for knocking over products and not picking them back up. If a player fills up his/her cart they could run back to the checkouts and receive a fresh one. The player with the highest total of products in their cart goes on to play the Bonus Sweep.
The Bonus Sweep is also played the same way. The winning team is given 60 seconds to find three products hidden in the market. The first clue leads to a product that possesses a second clue. If a player finds the third product before time runs out, they must run back to the checkout stand where they are awarded the money. The clues are delivered in various formats. Some clues were two line rhymes describing the product, which lacked the brand name at the end of the rhyme. Other cluess used puns on the name of the product. Sometimes, the cluess led to a movie, a fruit or vegetable in its section or a flower in a special kiosk located in front of the supermarket that was used only during this phase.
