::Hi Fwend,I dealt 9 and got 12. How is my deal wrong? How are my sets wrong? I need help in understanding the task description, as I create a deck of 81 cards, draw 9, and get various numbers of sets out of it. Thanks. --[[User:Paddy3118|Paddy3118]] 08:01, 11 February 2013 (UTC)
:::My understanding from the task description is that there is an "arbitrary" requirement to return only deals where there are exactly 4 sets. A brute force way of doing this is to repeatedly sample 9 cards from the pack until you get a deal that contains exactly 4 sets. HTH. --[[User:Tikkanz|Tikkanz]] 09:49, 11 February 2013 (UTC)
:::: You're asked to create the dealer code for an ''existing'' puzzle game, that happens to have these rules. They may seem arbitrary, but I'm sure the puzzle designers had a reason for it, which probably has to do with consistency of presentation and degree of difficulty.

::::: Sure. But from the point of view of someone solving the task on this site, the choice of 4 (or 6) is fairly arbitrary. I don't have any problem with that. I was just thinking that perhaps Paddy was over thinking the problem and that clarification might help. --[[User:Tikkanz|Tikkanz]] 11:20, 11 February 2013 (UTC)
