The application offers three very useful functionalities about the Spanish Christmas Lottery (el Gordo):

In the first place, you can check if a particular number has previously been awarded the first prize in the Christmas lottery. The program returns if the number and year in which it was awarded has ever been awarded.

Secondly, you can consult information about the first and last figures of the Jackpot's first prize in the previous draws. To do this, the user must choose the number of previous draws that he wants to examine. The application returns for both the first and the last digit the number of times that digit has been returned (number of occurrences of each digit as the first and last digit). That is, if we look at the last figure, the number of times it ended in zero, the number of times it ended in one, and so on up to the number of times it ended in nine.

Finally, the user can consult all the numbers that have been awarded with the Gordo throughout history. The application shows you both the winning number and the year in which that number was awarded.
