The old clock tower is striking midnight! The three ghost hunters quickly reload their green goo ammunition in their handmade power pistols and enter the castle. Let the ghost hunt begin! Together in Ghost Blaster, the players try to hit and trap the ghosts with the right amount of goo. Players must roll the dice in sequence and reveal the ghosts using the ghost hunter cards. Once the players have three of the same ghost cards face up, this ghost is caught and can no longer escape. But careful! If the players accidentally uncover a keyhole card, the ghost hunter is caught in the trap and must then go into the dungeon. Players can free him but that takes up valuable time! Their objective is to capture all of the ghosts before the ghost hour is over.
