Slow Block

A Slow Block is an item that appears in Mario Party. It is bought at the Mushroom Shop for 100 coins. It is the opposite of the Speed Block which rolls an eight, nine or a ten, since when it appears on a player's turn, the player can only roll a one, two or three.

Oddly enough, the Slow Block has a four on the top of the die even though it only allows the player to roll a one, two or three. This appears to be due to its artwork being a recolor of the artwork for the Plus Block and Minus Block.

Trivia

 * This block resembles the yellow ! Blocks of Super Mario 64, but with numbers on each surface instead.
