Tetromino art

Players have been able to manipulate tetrominoes under the naive line clear gravity of popular tetromino games to create artistic accomplishments. Some games reward the player for making specific patterns in the playfield. A well-known pattern is the ">" secret grade in the TGM series. Other games make such patterns the entire point of the game, such as "square" modes in The New Tetris and Tetris Worlds and "puzzle" mode in Lumines.

Some players make videos of the construction of tetromino art.

All clear

TGM series, Puyo Pop, and Lumines reward the player for clearing all blocks from the screen. TGM calls this a "bravo".

Vertical line

Clear the field except for five I tetrominoes in one column. TokusiN demonstrates this on Tetris DS in a video.

Greater than

If the player fills in all blocks on the lowest ten rows except the main diagonal (1, 1), (2, 2), ..., (10, 10), TGM games grant an automatic S1 grade:

When building this pattern, one tactic to leave the first two holes is by rotating an S tetromino on end, putting it at the left side, and clearing the middle line:

One rank is added for each additional row going the other way:

Negative tetrominoes

Create all seven tetromino-shaped negative spaces in the well, with each shape's perimeter completely surrounded by blocks or the playfield walls. (Suggested by DIGITAL[1])

Location of each hole

All six single floaters

Make an isolated block of each of I, J, L, S, T, Z colors that is not adjacent to the wall or to any other block. (Suggested by jujube[2])
