While other lotteries offer higher individual prizes, Spain's Christmas lottery is the most lucrative for its total prize money.
Despite an increasing number of coronavirus infections -- Spain scored Tuesday its pandemic record for new infections with almost 50,000 cases in one day -- the public is now returning to Madrid's Teatro Real operahouse after last year's hiatus.
Children from Madrid's San Ildefonso School call out the prize-winning numbers. They are followed by celebrations in bars and streets with winners drinking sparkling wine uncorked.
The state runs the lottery and funds several charitable efforts.
