Bowser's Pinball Machine

Bowser's Pinball Machine is a board that appeared in Mario Party DS. It is the final board to go through in Story Mode. When the player finishes successfully Bowser's challenge in the Story Mode, the board is unlocked and can be chosen in Party Mode. There are no Bowser Spaces on this board. There are Event Spaces that bring the player to the Bowser Zone or the Star Zone. By the Star Zone the player gets 1-3 stars. At the Bowser Zone, there are five ? Spaces. If the player stops at one of them, Bowser will spit out a Zero Flame, and the player loses all his or her Coins and Stars.

The board has a jackpot event towards the beginning of the board. Two icons will match up on the screen and the player must match a third icon to win the prize.

Landing on the ? Spaces near the flippers will knock the player all the way to the top of the board; the player will hit a bumper and then get ten coins. Landing on the ? Space near the roulette lets the player bet coins on where they think the spinner will land. There are three areas: ×2 is the largest, ×3 is the second smallest, and ×5 is the smallest. If the spinner lands on the area the player bets on, the player will win the number of coins they bet on multiplied by the number on that area. Landing on the ? Spaces after the roulette will load the player into the pinball machine, and they will be launched into the Bowser Zone or, if they're lucky, the Star Zone. Landing on a ? Space in the Bowser Zone will cause Bowser to unleash his "Zero Flame", which will cause the player to lose all of their coins and stars. Landing on the ? Spaces near the cannon will launch the player in the direction of their choice.

Story Mode
In Story Mode, this is the last board played. The heroes arrive in Bowser's Castle and realize they are still small. Bowser, along with Bowser Jr., picks them up and throws them in his Pinball Machine.

If the player has the most stars after ten rounds and wins, Bowser attempts to shrink them again with the Minimizer. However, Donkey Kong and Diddy Kong come at the last moment, although only coming for the free food in his party, and accidentally breaking the Minimizer, which makes everyone grow back to their normal size. Bowser then tells them that he has another weapon, the Megamorph Belt. The Superstar faces Bowser in the minigame Bowser's Block Party, and if they win, the player clears Story Mode.

Star
The Star is always on a random location on the board. Players can buy one Star for twenty coins (five if the Final 5 Frenzy shows Stars for five Coins). Once someone buys one, a new one appears.

Trivia

 * Despite being a Bowser-themed board, Bowser's Pinball Machine has no Bowser Spaces. It shares this trait with Bowser's Enchanted Inferno! from Mario Party 7.
 * If a player gets into the Bowser Zone due to a Space Swap hex, the usual message "Oh no! You're in the Bowser Zone!" will not pop up.
 * In the Korean release, the rule of the jackpot event is changed. The player earns coins when the UFO is in the central spinner when the player touches. The player can get more coins if the player react faster. The roulette event is also changed to Whac-A-Mole-like game. The player earns coins if the player hits Bowser or Bowser Jr, while the reward is decreased if Bob-omb get hit.
