Bug Hunt: Yankee Swap 2 plus Centipede. As in Centipede, each player has their own assigned wild rank. Otherwise, play like Yankee Swap 2: there is a communal hand in the middle, which players may exchange cards with.
Centipede: Each player has an assigned wild rank - the player to the dealer's left is 2, the next 3, and so on. Wilds do not change as players drop out.
