Clearing over four lines

In games with recursive gravity that reward a player for clearing as many lines as possible, an average player may clear nine lines or more.
Drop Z or T			
A player can clear over half the screen this way:

== General Tips ==
*Avoid creating empty columns that are over ten rows high. There will be no room above the platform to place any more than one or two I tetrominoes.
*Many cascade games use the traditional randomizer. Create the platform early to minimize the threat of an I drought.
== Creating the platform ==
A player is encouraged to create the platform over the far left/right column as early as possible. Since duplicate I tetrominoes need to be placed above the platform, it's better to place them while stacking than to place them after you have stacked high enough. The best way to create a platform would be to build up the second to last column from the left/right wall. A player would often use the starting tetromino as a base, place an I on that tetromino, and then place a tetromino above the I to create the platform.

Dedicated Platforms
Dedicated platforms are solely used to create the overhang above the empty column.
			
Cascading Platforms
Cascading platforms contribute to clearing the empty column.
		
Safety Platforms
If a player were to build a column too high, there are still a few countermeasures.
