Tug Of War may be used once by a player to challenge any opponent. Both players roll 12-sided dice equal to the number of bunnies that each player has in The Bunny Circle, and add the numbers together to get a total. The player with the lower total loses all of his bunnies to the Discard Pile. If the totals are the same, then neither player loses their bunnies. Double Free Agent, Specialty Bunny (double or triplet) or Celebrity Bunny (double or triplet – Ominous Onyx Booster Deck) cards count as a single bunny, and allow the player a single die roll each for Tug Of War.
