Reverse Dice Block
From the Super Mario Wiki, the Mario encyclopedia
Reverse Dice Block is a purple colored Dice Block that appears in Mario Party 10, but only in amiibo Party. As the name suggests, the block will have the opposite effect from a normal Dice Block. It is similar to the Reverse Mushroom in Mario Party 3. The Reverse Dice Block can appear if the player stops on a Special Dice Block Space.
