Perfect clear

An All Clear, Bravo Field Clear, or Perfect Clear occurs when the player clears the whole playfield without leaving any blocks behind.

In some multiplayer games, such as TOJ and Tetris Friends, performing one sends a large amount of garbage.

Perfect Clear Setup
In games that use Random Generator, it is possible to setup a Perfect clear with relative ease and high chance of success (though still a chance of failure) by creating 2 shapes, a 4x4 square and a TSZ stack. The rest of the field can be filled in various ways.


 * Basic Starting Shapes

Variance
This Perfect clear setup instead uses a single 6x4 rectangle shape on the left side.
