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. 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 (The Bowser Space appears in the board results screen). There are Green Spaces that bring the player to the Bowser Zone or the Star Zone. In the Star Zone, the player randomly gets 1-3 Stars.

At the Bowser Zone, there are five Green Spaces. If the player stops at one of them, Bowser will spit out a Zero Flame, and the player loses all their Coins and Stars (but not their items). Fortunately, one can only be hit by the Zero Flame if one lands on 1 of the 3 Green Spaces by the plunger. Although the plunger will most likely fire the player into the Bowser Zone, there is a one out of ten chance that they will hit a bumper that bumps them into the Star Zone. All of the Green Spaces in the Bowser Zone activate the Zero Flame. If the player has a Double/Triple Dice Set, Warp Dice Block, or the Star Pipe, they can easily escape the Bowser Zone and avoid the flame.

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. In the Korean version, the jackpot event changes slightly. The player gets coins if the UFO icon hits the central spinner. More coins are awarded the sooner the player reacts.

Landing on the Green 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 Green 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. As casino gambling is illegal in South Korea, the Korean version changes the roulette event to a Whac-A-Mole game. The player earns coins if they hit Bowser or Bowser Jr. while the reward is decreased if they hit a Bob-omb.

Landing on the Green 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

 * 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.
