In Magical Tetris Challenge, there are minoes that are 3×3, 4×4, and 5×5 squares to make the gameplay more challenging. Though the tetromino is moved and rotated as a unit, once it locks, the components separate by colors and fall. In The Next Tetris, Sticky mode of Tetris Worlds and Tetris Mania, Jewelry Master, and Alizarin Tetris, some tetrominoes are multiminoes, that is, the tetromino itself is divided into visible components.

**Even though the t-tetromino in the Tetris logo is not split into four minoes. *As of 2009, if hardware limitations do not allow all colors to be used, tetrominoes have distinct hues and patterns to differentiate themselves. Other names include straight, stick, strike, line, long bar, vav (or vov, waw), final nun, one, the cyan piece, the long skinny one, the slim jim, tetril, TGM-red, hot shot, long, slim dandy, the flashmaker, long boi, big poppa, thin lizzy, stack-em-up, Euclid's Arrow, four on the floor, George and hero.ĭue to I's design as a Tetromino, it can be used for a Tetris Line Clear, because of a design of 4 Mino's (Blocks) tall. This tetromino is very useful for filling deep 1-wide wells within your stack (Diagram 1), and is the only one to be able to clear 4 lines (a Tetris) within traditional rulesets (Diagram 2). If you know any other names for a tetromino, please list them in the section corresponding to the tetromino by editing the section. Tetris is still patented today, and the patent will expire in 2032. Another patent application was submitted in 2012. They were patented in 1996, but it expired two decades later.

The idea of tetrominoes is copyrighted to them. The Tetris Company owns the copyright and trademark on all seven tetrominoes.

The diagrams below will use the guideline colors. Since then, the color schemes associated with SRS and TGM Rotation have dominated new games, and 'the blue piece' is always J (see below). 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'.

Mario, or black-and-white systems*, each tetromino has a different color. In most games other than Tetris for NES, Tetris & Dr. Each tetromino has a letter name and several alternative names.
