Uno 2 - Small World is a card and puzzle game following the same principle as its predecessor. The player must get rid of all his cards. These are either numbered 0 to 9, or special cards. Special cards can make the next person pass the turn, change direction, force the other to draw two cards, a joker to choose between the four suits, or a joker but also forces the next person to draw four cards this time. When the player has only one card left, he is obliged to say "Uno". Otherwise, the player must draw two cards.
