I was playing Uno, and the card was a yellow 4. As I didn't have a yellow nor a 4 in my hand. I played the draw 4 card. Now should I have been challenged, I would have won the challenge. But my friend behind me in the rotation, jumped in with another draw 4, making it a +8. Now that he has played a +4, I am no longer challegeable, but would you be able to challenge him? I don't think you would be able to, since it wasn't his turn so technically he didn't have to play anything, plus it was a jump in. So can you challenge a jump in draw 4 card played?

SE Disclaimer: The current question regarding what happens to a challenged and improper wild draw 4 is unclear. My answer assumes that the "wild" part of a wild draw four is still in play (including whatever color was called.)

The "jumping in" and "chaining" rules you refer to are house rules/variants. There is no official rule that allows you to take a turn out of rotation (that rotation may change due to skips, reverses, and other card effects, but there's no playing out of order.) There is no rule that allows you to escape the effects of a card by playing another copy of said card, and no rule that then doubles the effect of the card to the next player. The way to deal with this, then, would have to be house ruled as well, and I haven't seen a ruleset that actually does.

So then... what should it be changed to. I'm afraid that is quite difficult to say.

First, the reasoning behind the wild draw 4 (hereby named as the WD4.) The rule "prevents" the play of the WD4 in situations where another card could legally be played. It's the only card that has this restriction. This rule in particular showcases just how much thought went into designing this game. Without this rule, the WD4 is simply a "better and more flexible draw 2." Why would you ever want a draw 2 when there's cards that would be more painful and be playable in more circumstances? This rule adds that little kicker to the situation. A draw 2 can be played (assuming a legal pile to play it on) at any time, allowing for someone to "save" an uno from the next player. A WD4 is somewhat less likely. It provides a weakness to the greatest card in the game, albeit small. It even provides some interesting mindgames (you're on uno and the player before you plays a WD4. Now, if you draw the 4 it's a major setback. But if you challenge successfully, you're still in the game (though unless you got really lucky with the color call you would still be drawing 1.)But if you challenge unsuccessfully you're back to 7 cards and possibly out of the running. So, did I play in desperation or am I trying to trick you?) For a game that's usually a luck fest, that's a really interesting twist. (now if only they did that with the skip cards too...) There's also the other reason of reducing the take that effect, and giving players the out of "look, it's the only card I could play, I didn't mean to!"

So...with that in mind, how is the best way to play this? There's 2 ways.

1) Don't play with chaining and jumping in with WD4's, keeping everything else the same. This keeps the premise of the WD4: the nuclear bomb that you aren't allowed to control.

2) If you really want those +8 moments, then do this: any and all WD4's played can be challenged, with respect to the card played just before the WD4 chain. (Using your example, the player who jumped in or you could be challenged, and if so it's on the basis of "could you play on a yellow 4?") If a WD4 is challenged unsuccessfully, the offender would draw 6 cards (the WD4 that was challenged + the penalty 2) and that WD4 would be considered "dealt with." The current player can attempt to challenge other WD4's if they wanted to.

If a WD4 is successfully challenged, then all WD4s played after the offending WD4 are cancelled, and returned to hand. (reasoning: the "penalty" for an improper WD4 should be known when the card is played. Read on...) The offending player must then draw for the WD4 he played, and any others played before. This puts the onus on the jumping in player, as they "accepted" the raised stakes (where as the first player had no clue what was going to happen.) The offending player is allowed, however, to challenge any WD4 played before their play (i.e. the jumping in player, if caught, could challenge the first player, with the usual +2 card risk. If successful, their play is cancelled per the above rules.)

In any case: if any challenge is successful then, after the cards are drawn, the player who made the successful challenge then plays the next card (with whoever played the most recent not challenged call picking the color.) If no challenge was successful, that player's turn is skipped (per the normal rules) and the next player is up.

I would personally increase the penalty for an improper WD4 by 2 cards if the WD4 was chained, as part of the nature of the WD4 was the fact you can't aim it, and chaining would allow you some aim. But that's just me, and would probably require some testing first.

  • I would like to point out that there is a specific rule already in the game related to challenges after the next player has played. In the case that a player only has one card and forgets to call uno they can't be challenged on that mistake after the next player plays. I see no reason why that should not be different for any other challenge such as a wild draw four.

    @JoeW I agree with respect to the rules as written. The problem is, the rules that are being used aren't the rules as written. There is no rule allowing for chaining WD4's...or chaining anything for that matter. The reason for the WD4 challenge is that the WD4 "can't" be used unless there's no other option. Allowing the OP's situation of "if someone chains it we're both immune and you just get stuck" removes this mechanic entirely.

  • The last person to chain the draw four can still be challenged

  • You could do it that way as well if you preferred (although it does open the door to collusion..."Hey cover my WD4 with yours before I get challenged and we can make this sucker draw 8 cards!") The nice thing about house rules is you can play it any way you prefer :)

  • Well if your group is playing that way then it has other issues. Not to mention that by basic rules the only person who can challenge a wild draw four is the person who will be drawing 4 cards.

The rules for a Wild Draw Four actually limits who can call a challenge to the person that will draw the cards. So for your house rule of chaining wild draw four you can't be challenged since the next person accepted and and played another wild draw four.

Uno Rules

Wild Draw Four – This acts just like the wild card except that the next player also has to draw four cards as well as forfeit his/her turn. With this card, you must have no other alternative cards to play that matches the color of the card previously played. If you play this card illegally, you may be challenged by the other player to show your hand. If guilty, you need to draw 4 cards. If not, the challenger needs to draw 6 cards instead.

In the case of chaining them I would guess that for a successful challenge the last person to play it would draw all the cards. For an unsuccessful challenge the person doing the challenge would draw 6 times the number of wild draw four played (after a few are chained the risk of just drawing two extra cards is pretty small).
