Mattel has launched the UNO World Championship Series, a competitive tournament for the popular card game that offers a $50,000 grand prize to the eventual winner. The move takes UNO beyond casual family game nights into organised esports-style competition, with a live-streamed final designed to give the game global visibility.

Players can qualify via the UNO! mobile app or by attending in-person qualifiers in Orlando (3 October), Chicago (10 October) and Los Angeles (17 October). The grand final will be broadcast live from Los Angeles on 11 November and streamed worldwide on Twitch. Alongside the tournament, Mattel is releasing a range of branded products, including a Championship Series Tournament Set, a Championship Series Belt and a Card Shuffler, each priced at $19.99, plus a more advanced Expanded Tournament Set at $27.99.
