Hey kiddo, have you ever played the game Tetris? You know how you have to fit different shapes together to make a whole line disappear? Well, those different shapes are called tetrominos!
Now, a tetromino is a shape made up of four little squares that are all stuck together. They can come in a variety of shapes, like a long skinny one, a square one, or an L-shaped one.
When you're playing Tetris, the game gives you one tetromino at a time and you have to fit it into your game board. It's like putting together a puzzle! If you can fit a whole row of tetrominos together, the row will disappear and you'll get points.
So remember, tetrominos are the little shapes that make up the game of Tetris. Put them together right and you'll win the game!
