|Coin Block Clip|
The Coin Block Clip is an intermediate trick used in Super Mario Maker. This trick allows Mario to go over blocks at the top of the screen, which is normally not possible.
As of version 1.47, Coin Blocks can now always be jumped over, meaning this trick only works in levels created before this version.
How It Works
When a coin block is hit with a shell it will very slightly move upwards. During this time the block is "disconnected" from the top of the screen, which allows Mario to go over it. If Mario is over the block when it goes back to its normal state he will be considered inside of a wall and can freely walk through blocks at the top of the screen.
