Event Space

"Now here's a big mystery! The Green Space! Land on one to unleash a special event!"

- MC Ballyhoo

The Event Space (also known as a Happening Space, a Green Space, or a Question Mark Space) is a green space with a question mark on it typically found on the various game boards in the Mario Party series. Ordinarily they activate special board-specific events that can change the outcome of a turn or even a whole game.

In Mario Party 8, the shape of the space differs depending on the board, including the tutorial map. In-game, these spaces were known as Happening Spaces up until Mario Party 6, when their name was changed to Green Spaces. In most games, a Bonus Star is awarded to the player that lands on more of these spaces than any other player at the end of the game.

In Mario Party 3 ' s Duel Mode board, it's also known as the Happening Space, and a roulette starts with three random events.

The Green Space returns in Mario Party 9, renamed the Event Space, but with the same effects. In Mario Party: Island Tour, they appear in Shy Guy's Shuffle City, and trigger an event wheel. The misconceptional blue and red ones are actually Lucky and Unlucky Spaces.
