The term "Six Kings Slam" refers to a high-profile tennis exhibition tournament held in Riyadh, Saudi Arabia, during the Riyadh Season. It features six of the top male tennis players competing in a knockout format across three days with a rest day in between, following ATP rules that prevent players from competing three days in a row in exhibitions. This event does not award ATP ranking points and match results do not count towards official head-to-head statistics. The tournament offers massive prize money: each player receives a guaranteed participation fee of $1.5 million, and the winner earns an additional prize, totaling around $6 million in recent editions, making it one of the richest single payouts in tennis history. The "Six Kings" refers to the six top players invited, including stars like Jannik Sinner, Carlos Alcaraz, Novak Djokovic, Rafael Nadal, and others. The event showcases elite tennis without the pressure of official rankings, purely as a lucrative exhibition. The word "quanti" you asked about is Italian and means "how many," but in this context, it may have been part of a question about how many sets or matches the Six Kings Slam involves. In summary, the Six Kings Slam is a prestigious, lucrative tennis exhibition held annually in Riyadh with six top players competing for large prize money over a few days without ATP ranking implications.
