hy , i would like to suggest a option ask a confirmation before junking cards if this option is set to off a message do you really want to junk that card in 1000 miles and uno should be disabled .What you all think about this?

no, because sometimes some people do it by mistake so, they should warn them.

You mean like in 1000 miles for example if you pressed j or delete key the card junked directly with out asking you if you want to junk it? good suggestion.

yes but thats why i say it should be an option and not a requirement sometimes when you know what you are doing you can just turn it on and again if you notice that you are making a lot of mistakes you know that option is not for you and you can turn it on

The same option is in the uno in rs games, but, it destroyes the point of uno here. Here it is game for fast players and asking for yunking, it would be big break for players, who want actually be fast.

agree with you, nidza

Or maybe it could be delete key to show a confirmation question and j to junk it directly. What could you tell me?

I like that idea.
Maybe the shift key could be used to bypass the prompt altogether.
