The official rules for the classic uno game are:
To win a match you must be the first player to get rid of all your cards. Players play in turn: either take a card from the pile or place one on the table if it matches the last card placed on top. Other moves are not allowed.
Two cards are considered matching if they have the same color, same number or same symbol. There are 108 in the deck: normal ones with numbers 0 to 9 for each color(red, yellow, green blue) and special action cards:
- Skip: next player in sequence misses a turn
- Reverse card: order of play switches directions (clockwise to counterclockwise, or vice versa)
- Draw Two (+2): next player in sequence draws two cards and misses a turn
- Wild card: player determines the next color to be matched (may be used on any turn even if the player has matching color)
