He glared back
"NO YOU'RE NOT-CHECK THE RULES IF YOU DON'T BELIEVE ME!!!"
"AIGHT WELL MAYBE YOU SHOULD READ THEM AGAIN!!!"
He threw the rulebook at him-
A Player may play a "Wild Draw Four" card even if they have a matching number or word card of a different color in their hand. If you suspect that a player has played a Wild Draw 4 card illegally, you may challenge them.
A challenged player must show his/her hand to the player who challenged. If the challenged player is guilty, he/she must draw the 4 cards. If the challenged player is not guilty, the challenger must draw the 4 cards, plus 2 additional cards.
Only the person required to draw the 4 cards can make the challenge.
