Tetrominos, occasionally known alternately as Tetrads, Blocks, or Tetriminoes, are the blocks used in every known Tetris game. They come in seven shapes, all of which can be rotated and then dropped. Tetrominoes all have an area of four squares. In certain Tetris games, the colors of them vary.
A tetromino, is a polyomino made of four square blocks. The seven one-sided tetrominoes are I, O, T, S, Z, J, and L.
The spelling "tetromino" is standard among mathematicians. The Tetris Company had preferred tetramino around 1999 and has used tetrimino since 2001.
The Basic Tetrominoes Edit
Each tetromino has a letter name and several alternative names.
In most games other than Tetris for NES, Tetris & Dr. Mario, or black-and-white systems, each tetromino has a different color. However, before about 2001, these colors varied from product to product, making it difficult for people who play different games to discuss "the blue piece". Since then, the color schemes associated with SRS and TGM Rotation have dominated new games, and "the blue piece" is always J.
The Tetris Company owns the copyright and trademark on all seven tetriminoes. The idea of tetriminoes is copyrighted to them. They were patented in 1996, but it expired in 2016. Another patent application was submitted in 2012.Tetris is still patented today.
Other names include straight, penis, the phallic piece, stick, strike, dick, cock, line, the cyan piece, the long skinny one, tetril, TGM-red, and long. This is the only tetromino that can clear four lines outside of cascade games.
Other names include square, box, Q, A, basil, circle, TNT-gray, the yellow piece, round, ass, sun, butt, butt cheek, and block.
Other names include The Tetris Block, up, down, left, right, the magenta piece, Y, T turn, ted, triangle, middle finger, pyramid, TNT-yellow, TGM-blue, tire, te, and tee.
Other names include the green piece, right turn, inverse skew, right skew, H, Wa, saw, backwards-red, right dog, right kink, and right snake.
Other names include the red piece, left turn, outverse skew, right skew, S2, N, Wb, zaw, backwards-green, lightning bolt, left dog, left kink, and left snake.
Other names include the blue piece, gamma, ghe, inverse L, Va, reverse L, left L, left periscope, led, left elbow, or left gun.
Other names include the orange piece, alpha, outverse J, Vb, L2, right L, TNT-magenta, right periscope, jed, right elbow, or right gun.
In The Next Tetris, Sticky mode of Tetris Worlds and Tetris Mania, and Jewelry Master, some tetrominoes are multiminoes, that is, the tetromino itself is divided into visible components. Though the tetromino is moved and rotated as a unit, once it locks, the components separate by colors and fall.
In some games like Magical Tetris Challenge, there have Minos that consist of 5 to 25 squares to make the gameplay more challenging.
The "Heaven" PolyminoEdit
In "Tetris Heaven" as concieved of by Randall Monroe in xkcd.com/888/, the "Heaven Block" is the exact size and shape required to eliminate every open row up to the highest column. In most fanmade adaptions, the piece is portrayed as a single square when shown as coming next.
