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, move on to the next one. But if the player gets the right chest, the player will have to grab a new key as the process repeats. If all the chests are open, the player wins.
