El Gordo de la Primitiva


El Gordo de la Primitiva, commonly known as El Gordo, is one of the Loterías y Apuestas del Estado.
The largest prize given at the Spanish Christmas Lottery, is also referred to as 'El Gordo'.

How it is played

Tickets consist of two grids, one with numbers from 1 to 54 and the second from 0 to 9. Players have to pick five numbers in the first grid and one in the second. The key number also serves as return number.
The tickets can be bought from Monday to Saturday in over eleven thousand locations in Spain and cost €1.50 per grid.
By selecting six to eleven numbers in the first grid you can make multiple bets with the same ticket.

Drawing

Drawings are held every Sunday at 13:00.
Five numbers are drawn at random from 1-54, and then another one for the key number from 0-9. Prizes are awarded to tickets whose numbers match the drawn ones. First prize is for a perfect match, second for 5+0, third for 4+1, and so on until 2+0, totaling 8 prize categories. Tickets whose key number matches the drawn key number are entitled to a refund of the amount played.
A ticket can hold more than one bet, but each bet cannot win more than one prize.

Prizes

From the total amount collected T, the state keeps 45%. 10% is reserved for returns, and 45% is distributed on prizes.
For all categories, the prize is shared in equal parts among all matching tickets.
First category has a guaranteed minimum amount of five million euros. In the case of no first category winners, 50% of the amount reserved for the first category is accumulated to the guaranteed amount for the next drawing, often leading to huge bonus prizes.
The amount for the rest of prizes is then reduced by the number of tickets with 2+0 prizes, each of which receive a fixed amount of 3 €. The resulting amount R is then distributed like this:
Special rules apply in case any of these categories remains void, and also in case any category were to have lower prizes than a lower one.
