Tetris Gameplay Explained

Tetris gameplay can be explained as a video game consisting of rapid hand-eye coordination, careful short-term planning, and sensible decision-making. The objective is to keep the grid as clear as possible, removing cells line by line through strategically placing falling tetrominoes.

The area of play is a vertical grid called the matrix, where you deal with the falling pieces that need arranging. Seven piece types (tetrominoes) randomly fall from the top of the matrix. The tetromino shapes resemble letters I, J, L, O, S, T, and Z.

Game Setup

Starting the Game

Depending on the Tetris version you intend to play, options can vary in availability. Some have difficulty-level or speed settings, while other browser-based versions allow you to begin playing from the jump without anything to adjust.

Understanding the Interface

The most basic element of the Tetris interface is the matrix; the “next piece” screen is often placed to the upper right, with the score nestled in that same general area of the screen. Some versions have directional arrows that can be clicked with the mouse if a player prefers that over using a keyboard.

Basic Gameplay Mechanics

Tetrominoes

There is a total of seven tetrominoes falling from the top of the matrix. They are the “O,” a square made from four cells, and an “I,” a straight line of four cells; a “T,” a row of three cells with one more stacked in the middle; an “L” shape, four cells in a row with one more stacked on the right-hand bottom side; a “J” shape, four cells positioned in the exact reverse hand of the “L” shape; an “S” shape, two cells in a row, with two more cells stacked on top of them, offset toward the right; and finally a “Z” shape, the opposite pattern of the “S” shape.

Moving and Rotating Pieces

Shapes can be rotated clockwise and counterclockwise, whichever direction best suits the location where you intend them to land. Each click of the on-screen “up” arrow or the corresponding keyboard button press will move the piece 90 degrees from its last position.

There are three ways that pieces can be shifted left and right on the matrix. The first is by the left and right arrows that might be on the screen pressed by left-clicking the mouse. The second is by holding the left mouse button on the falling piece and swaying the mouse left and right. This will allow you to move it left and right. The third is by using the left and right arrows on your keyboard.

Hard Drop and Soft Drop

A player can intervene in two ways to speed up the game: by using soft and hard drop options. A soft drop is made by pressing the down arrow, which increases the speed at which the tetromino falls. A hard drop teleports the piece immediately to its landing spot, which can be done using the spacebar on most browser-formatted game versions.

Clearing Lines

Line Clearing

The point of the game is to create full lines or series of lines stretching from one side of the matrix to the other. When lines of cells are completed without gaps, the line disappears, collapsing any cells that might be atop it. The longer you keep the play area clean and free of cells, the longer your game will be, and the better you’ll score.

Scoring System

Generally, a completed line will score you 20 points. Two lines at once score 60, and three at once score you 120 points. Clearing four lines at once is called Tetris and is the highest-scoring move in the game, bringing the player 1200 points in most Tetris variants.

Increasingly Difficult

Level Progression

As the game progresses, the falling speed increases, increasing the challenge.

Handling Speed

Handling the increase in speed gets easier through progression and practice. A good way to stay ahead is to be keen on the next piece and decide where it will go after placing your current piece.

Winning and Losing

End of the Game

If the tetrominoes reach the top of the matrix, it’s game over.

High Score

Your goal as the player is to get the highest score possible per session, achieving higher scores as you improve by the game’s end.

Strategies for Success

Planning Ahead

The next piece window is there for a reason. Utilizing it will help you get farther along after the game speeds up.

Creating a Tetris

Creating a Tetris is the fastest way to rack up the points, so, if possible, try to build the lines up four tall, leaving open one slot to cram an “I” into when the time is right.

Managing the Stack

Keeping the stack of cells low on the matrix is the safest way to progress, so keep the area you’re playing in at the bottom for as long as you can.

T-Spin Techniques

A T-spin is a technique using the “T” piece. The idea is to use it to fill a t-shaped gap at the last split-second, usually after sending it through a space two cells wide. Think of it as squeezing it into place just before it lands.

Common Mistakes to Avoid

Stacking Too High

You have room to play, but gambling can cost you. It’s best to stay at the bottom to prevent lopsided stacking and an early end to the game.

Ignoring the Next Piece

It would be best to place pieces in a manner that properly sets up your next piece. If you ignore what’s coming next, you have no clue what you’re setting up for.

Over-Rotating

One rotation too much can cause you to create gaps that wouldn’t have happened otherwise, so try to avoid over-rotating the piece (particularly when it’s close to landing).
