King Bob-omb's Powderkeg Mine (also known as Gold Rush Mine) is a Super Mario Party board. As its name implies, it is inhabited by King Bob-omb. The board takes place within an underground mining facility, with King Bob-omb standing in the center. A vein of gold is located at the left side of the board and can be interacted via Event Space, allowing the player (or CPU) to earn coins. If the player lands on an event space in the middle of the board, King Bob-omb’s counter go down by 1. If it goes down to 0, he’ll explode, and any players inside the court loses half of their coins.
|The player that lands on an Event Space decreases by 1 during the countdown. Once it reaches to 0, King Bob-omb will explode. The players surrounding him will lose half of their coins. King Bob-omb reappears and the countdown restarts from 5.|
