Negative number cards
Negative number cards play and act like positive number cards but have negative scores if they remain in a player's hand at the end of a round. Negative number cards can be played during events where number cards are required.
In Hot Potato, negative number cards back-skip that many positions in the direction of play. For example, skipping -2 players moves play behind the player in the direction of play. Skipping -1 players means no player is skipped and the player must play again.
Pick a Color Dump
