Play UNO just like the original game! Click Single Player to begin! You can play with one of 4 game modes. - Single Game: Play just a single round of UNO. The game ends as soon as everyone but one player finishes; the player who goes out first, wins! - Standard: Play with the official rules of UNO. Points are won by going out first in rounds; points are scored based off the cards their opponents are holding. First to reach the score limit wins! - Reverse: Play with an alternate variant of UNO. Try to avoid holding the high-scoring cards when someone wins a round! Points go against the player who holds a specific card. The player with the lowest score when someone reaches the score limit, wins! - Challenge: Plays like Reverse, but the goal is to be the last player standing! Players who reach the score limit are eliminated and the match continues until 1 player remains! You can go to Match Options to change the Score and Round Limits. When a round limit is set, the match ends when either limit is reached. Scoring: - Number Cards score whatever number is on the card. - Action Cards score 20 points. - Wild Cards score 50 points. To play a card, click on the card at the bottom. Click the deck next to the discard to draw a card. In certain cases, you will be given a blue box at the bottom; answer the question relating to the current situation. Want to play with against 4 or more other opponents (up to 9)? Now you can! How many players do you want to play against? 1-on-1 battle? 10 player free-for-all? Up to you! All other players are controlled by the CPU. Any player names you enter might be used by the CPU in future matches until you close the project! Note: You usually can't see your opponents' cards. The exception is when you decide to challenge a Wild Draw 4, in which you see the cards of the player you're challenging for 4 seconds (which is used to determine if the challenge is successful or not). More instructions in-game (click the Instructions button in the Main Menu). Have fun!
