In order to maximize your chances of going home with winnings, webmaster Clark has kindly provided you with a formula you can use to determine if it is to your advantage to try for the Joker, or to take the 50/50 cash in the can:

 

 

If (Money in the can) * (# Cards left in the deck) > (Joker Pot)

 

Then take the money in the can.

 

Otherwise, try for the Joker.
