not enough details for us to act on

I think "The Poker of" means Four of a kind
And there is 7 cards from which 5 are your best hand
( 2 cards in your hands + 5 cards on the table )
so in this case for example

Your hands -> K + 7
Table -> 2 + 4 of Jacks
Opponents hands -> 6 + 8

In this case Your best hand of 5 from avalible 7 cards would be -> 4xJ + K, and your opponents would be -> 4xJ + 8 and you will win
So this case is possible :)

give the actual inputs/outputs, please. For instance, what do you call "poker of"? a square? if so the one with the king would still be winning, so I guess that:

• either that's not the test you're failing
• or you're missing something else.
