- Not to be confused with Roulette Block.
Slot Blocks are a type of block appearing as the main function of Lucky Houses in Super Mario 3D World and Super Mario 3D World + Bowser's Fury. Lucky Houses contain four Slot Blocks with constantly scrolling images of five power-ups (the Double Cherry, Fire Flower, Boomerang Flower, Super Leaf, and Super Bell), which characters stop by hitting them. When all four Slot Blocks are stopped, the player receives a certain number of coins dependent on how many images are matching.
