The Bonoloto lottery is a daily event organized by the State Lotteries and Betting institution, held every day from Monday to Sunday in the designated lottery hall. This draw encompasses a variety of prize categories, including the first category for those with six correct numbers, followed by subsequent categories for five matches plus a complementary number, five matches alone, four matches, three matches, and finally, the reimbursement. The prize amounts are contingent on the total revenue generated and the number of winners in each prize category.

To participate in the Bonoloto, players are required to select a minimum of six numbers ranging from 1 to 49 for each bet. These numbers can be personally chosen by the participant or generated randomly by the lottery administration's machine. Participants can choose between single bets, involving six numbers, or multiple bets, where more than six numbers (up to eleven) or just five numbers are selected per bet.

The cost of a single bet is set at €0.50, but each lottery ticket must amount to at least €1. Hence, players must include a minimum of two bets if their ticket is to partake in a single draw. During each draw, in addition to the six winning numbers, a complementary number and a reimbursement number ranging from 0 to 9 are also drawn.

The Bonoloto draws occur every day, commencing at 9:30 PM, and can be observed live through the official State Lotteries and Betting website. Once the draw concludes, participants can verify the winning numbers via the same official website or through EL PAÍS's web page.

Other lotteries are also available, but it's important to note that EL PAÍS does not assume responsibility for any errors or omissions that may occur. The only valid official list is the one provided by State Lotteries and Betting.
