From the Super Mario Wiki
A Dash Space is an uncommon space that is first present in Mario Party 9 and then Mario Party: Island Tour.
Mario Party 9
When a player lands on a Dash Space, he or she will get to roll an extra time with the Dice Block. If a Captain lands on another Dash Space after he or she lands on a Dash Space, then the Captain still get to roll the Dice Block an extra time. Normal Dice Blocks can only be used by the Captain landing on the Dash Space.
Dash Spaces also appear during several Captain Events. This includes Scaredy Rat Race, in which the Scaredy Rat rolls 1-3 Dice Blocks instead of the standard 1-6 Dice Blocks after landing on these spaces.
Mario Party: Island Tour
Dash Spaces reappear in Mario Party: Island Tour. Their design has changed to a blue space with a plus sign next to it with a random number. They have the same function as in Mario Party 9 with a new rule. Instead of rolling another dice block, the player moves the number of spaces placed on the space.
