The primary objective of Dos is to discard all cards in one’s hand before anyone else does (and earns points from the cards still left in other player’s hands). Like Uno, you have to discard your cards by matching the cards in the centre, but here in Dos, you can only match them by number. The numbers need to be matched first, and then only the colour is noted. Colours only earn a bonus called a Colour Match Bonus. The first player to reach a score of 200 points (or any number the players agree on) is the game winner.
