Level B-24 is the eighth and last course in the Bonus 3 set and the twenty-fourth Bonus Level overall in Mario vs. Donkey Kong: Tipping Stars. By extension, it is also the final level of the game. It is the only level set in Shimmering Gold Palace and is unlocked by earning 87 trophies, which implies earning a three-star rating in all previous levels.
The level exclusively features eight Gold Mini Marios to fit with the theme of the level.
The course's layout is composed of a large number of slopes leading onto each other. A short gap with a Pink Block space is present between each consecutive slope and can be turned solid to lead the Minis on to the next slope or be left transparent to allow the Minis to go through the gap. While most gaps lead onto other slopes, some drop the Minis onto spike traps and should be kept covered. The slopes usually lead into Split Pipes which warp the toys at the top of another series of slopes.
Every Mini starts on the blunted top of a slope. Upon activation, one Mini may initiate other Minis on its way as it slides down the slopes, causing a chain reaction. The course is scattered with a great amount of Large Coins and the Goal Door is located on the bottom left, which can be reached via two openings.
The M Coin is floating right above the Goal Door. The Minis can reach the coin, as well as the door, by dropping through the gap above as they slide on slopes.
