Invented in 1971 near Cincinnati, Ohio, Uno is one of the most popular card games ever created. And while the game itself continues to provide hours of entertainment, the deck itself was in need of a refresh. This minimalist version was made by designer Warleson Oliveria and features an all-black rear face with bright colors on the front. He even added two new cards with some new rules to provide a fresh challenge for game veterans. Mattel liked it so much that it's been added to the official Uno family.
