Control Coin

Control Coins are a type of moving coin in Super Mario World and its reissue. They are usually released from certain ? Blocks called Control Blocks, and they move in the direction the player presses on. They are found in the Donut Ghost House, Donut Secret 2, the Valley Ghost House, and Star World 5. Control Coins also appear in the World-e levels Doors o' Plenty and Vexing Doors from Super Mario Advance 4: Super Mario Bros. 3, where they serve the same purpose.

If Mario or Luigi hits a Switch Block, the coins become Empty Blocks, similar to snake platforms, which Mario or Luigi can ride while still controlling the blocks. However, if the Control Coin touches a wall or obstacle, it stops moving and can no longer be controlled. The chain also stops if Yoshi eats the leading coin, which causes the switch's background music to play indefinitely. Control Coins also have a finite number of coins, after which it stops, but not in Super Mario World.

In Super Mario RPG: Legend of the Seven Stars, a similar coin appears in one of the rooms of the Sunken Ship, but it moves independently on a predetermined path, leaving coins behind. If Mario can collect every single coin the Control Coin leaves behind, he earns another one of King Calamari's clues. Similar coins also appear in Super Mario 3D Land, Super Mario 3D World and its port, and Super Mario Run, though the player only gets applauded for collecting them all.
