Treasure Dome!

Treasure Dome! is a single-player Bowser mini-game found in Mario Party 7.

Gameplay
The player attempts to get the key to the correct chest within the time limit. If the player gets the wrong chest, he or she should move on to the next one. But if the player gets the right chest, the player has to grab a new key as the process repeats. If all the chests are open before the thirty seconds are up, the player wins.

Trivia

 * The mini-game bears a resemblance to Coffin Congestion, but there are no items.
