completely unique. Warleson Oliviera's minimalistic design for UNO was brought from concept to reality by Mattel in less than 30 days! Game play is like classic UNO. Players match cards using color and numbers. Wild and challenge cards can change the momentum of the game. Special graphic symbols have been added to each card to help identify the color(s) on that card. This will allow players with ANY form of color blindness to easily play! Designed for 2 to 10 players, ages 7 years and older! This beautiful special edition of the much-loved card game makes a great toy for any UNO fan.
