is the six can come out from die one, die two or die three.

Can a draw four card be placed on a draw two card in the game uno?

When the Draw 2 card is played, the next player only draws two cards; his turn is forfeited.

The next player after the one who drew may play the Wild Draw 4 and declare the color, but only if he does not have a card of the same color as the Draw 2. If the next player, the potential victim of the Wild Draw 4, doesn't believe that he didn't have a card of the same color as the Draw 2, that player may challenge. At that point the one who played the Draw 4 must show his cards. If the challenger was right, the one who played the Draw 4 picks it up, plays a legal card, and draws four cards. If the challenger was wrong, he must draw two extra cards in addition to the four.
