Tetriminos are the colorful shapes made up of four connected squares that players manipulate in the popular video game Tetris. Each Tetrimino can be rotated and moved left or right as it falls from the top of the screen. The goal is to fit these shapes together to create complete horizontal lines, which then disappear, earning points for the player. There are seven different types of Tetriminos, each with a unique shape, including the I, O, T, S, Z, J, and L pieces. Mastering how to use these shapes effectively is key to achieving high scores and clearing levels in the game.
