A 50/50 Weapon requires that the player whose bunny is being attacked must roll the two dice indicated on the card after stating which of the two will roll the higher number. If the player is correct, the bunny survives. If the player is incorrect, the bunny dies. If the dice roll the same number, the player must roll again.
- Each 50/50 Weapon is also a P-Card. If the player to launched the weapon has the Black Pawn, he may save the card and use it a second time.
- Since a 50/50 Weapon has no specific weapon level, it cannot be purchased from Rooney's Weapons Emporium and must be discarded to the regular discard pile. Lucky Clover, Lucky Horseshoe, and defense cards have no effect against the weapon.
- A bunny with the Heavenly Halo or Angel Wings and any bunnies abducted by Area 51 or Mothership are not affected by a 50/50 Weapon.
