Official Rule Breakdown
According to the Mattel Official Rulebook (Uno Basic), a player may play a Wild Draw 4 card even if they have a matching number or word card of a different color in their hand. However, if you suspect that a player has played a Wild Draw 4 card illegally (meaning they actually possessed a card that matched the color of the card previously played), you may challenge them. Upon a challenge, the player must show their hand to the challenger. If the challenged player is found guilty of playing the card illegally, they must draw the 4 cards. If the challenger is incorrect and the player is innocent, the challenger must draw the 4 cards plus an additional 2 cards, for a total of 6 cards.
Step-by-Step
- Step 1: Suspect the player played a Wild Draw 4 card illegally (they had a matching color card).
- Step 2: Declare a challenge to the player.
- Step 3: The challenged player shows their hand to the challenger.
- Step 4: Determine guilt: if guilty, the player draws 4; if innocent, the challenger draws 6.
Example Play Situation
Alice plays a Wild Draw 4. Bob suspects Alice had a Blue card that could have been played instead, so Bob challenges. Alice shows her hand and reveals she had a Blue 3. Because Alice is guilty, she must draw the 4 cards.
House Rules
[HOUSE RULE] In the 'Progressive UNO' variant, players can play consecutive Wild Draw 4 cards; the next player must play another Wild Draw 4 to make the next person draw 8 cards.
