There's a bug in Farkle. For example: if you roll 1 1 2 3 4 5 it won't let you put in the extra one you either have to bank or roll.

Hi,
in Farkle, if you roll 1 two times, in the list it will show only 1 of them.
This is normal however, after selecting this first 1, the second one will appear.

In addition, you can't roll if you don't take at least one of the available dice. That is a rule, not a bug.

If you meant something else, please explain better, because otherwise I am not sure what is wrong or what you are trying to say.

Okay thanks.
