UNO Flex introduces new gameplay elements to the classic UNO card game. The set includes Flex Cards with unique abilities—players can change a card's color using the Power Card if it displays a green checkmark, while a red X means they must wait. Flex Draw Two requires all other players to draw one card, and Flex Draw Four lets the player select who draws four cards. The Flex Wild All Draw forces every other player to draw two cards, while Flex Skip skips all players. The game is colorblind-accessible, featuring graphic symbols on each card to help identify colors, ensuring players with any form of color blindness can participate. Designed for 2 to 8 players ages 7 and up, UNO Flex adds strategic twists to the familiar gameplay, making it suitable for family and group play.
