+--- Part Two ---
+
+To make things a little more interesting, the Elf introduces one additional
+rule. Now, J cards are jokers - wildcards that can act like whatever card would
+make the hand the strongest type possible.
+
+To balance this, J cards are now the weakest individual cards, weaker even
+than 2. The other cards stay in the same order: A, K, Q, T, 9, 8, 7, 6, 5, 4, 3,
+2, J.
+
+J cards can pretend to be whatever card is best for the purpose of determining
+hand type; for example, QJJQ2 is now considered four of a kind. However, for the
+purpose of breaking ties between two hands of the same type, J is always treated
+as J, not the card it's pretending to be: JKKK2 is weaker than QQQQ2 because J
+is weaker than Q.
+
+Now, the above example goes very differently:
+
+```
+32T3K 765
+T55J5 684
+KK677 28
+KTJJT 220
+QQQJA 483
+```
+
+- 32T3K is still the only one pair; it doesn't contain any jokers, so its
+  strength doesn't increase.
+- KK677 is now the only two pair, making it the second-weakest hand.
+- T55J5, KTJJT, and QQQJA are now all four of a kind! T55J5 gets rank 3, QQQJA
+  gets rank 4, and KTJJT gets rank 5.
+
+With the new joker rule, the total winnings in this example are 5905.
+
+Using the new joker rule, find the rank of every hand in your set. What are the
+new total winnings?
