Original Tetris Game Instructions

If you've ever played Tetris before, this should be very familiar. Blocks of various shapes and colors drop one-by-one from the top of the game. Your goal is to completely fill rows of blocks at the bottom of the screen.

Tetris Rules. Tetris is a super fun and addictive game that you can play on almost any device. Here are the basics:

The Tetris board is 10 columns wide and 18 rows high. That's where you stack your pieces, which are called tetrominoes.

Tetrominoes are shapes made of four squares. There are seven different kinds: I, O, L, J, S, Z, and T shaped.

The tetrominoes fall from the top of the board one at a time. You can move them left or right, or rotate them clockwise or counterclockwise. You can also make them fall faster or drop them instantly to the bottom.

Your goal is to fill up horizontal lines with no gaps. When you do that, the line disappears and you get points. The more lines you clear at once, the more points you get. If you clear four lines at once with the I-tetromino, that's called a Tetris!

The game gets harder as you go. The tetrominoes fall faster and faster, and you have less time to think and react. The game ends when the stack of pieces reaches the top of the board and you can’t fit any more.

That's pretty much it Tetris is simple but challenging, and it never gets old. You can always try to beat your own score or compete with others online.

Old Instructions. The instructions below are for the old Adobe Flash version of the game.

HOW TO PLAY. Each time a row is completed, the row disappears and all the blocks above it drop down one row. If there is a hole in a row where you failed to fit a piece, that row will not disappear.

Complete levels for points. Each level you advance is more difficult than the level before (blocks fall faster). The game is over if any block gets stuck at the top row of the screen.

CONTROLS. Press the Up Arrow key to rotate a piece. Use the Right and Left Arrow keys to move pieces left and right.

The Down Arrow key moves the piece downward faster. To drop a piece to the bottom instantly, press the Spacebar.

You can also have the option of starting at a higher level. Click the Question Mark button, then type a number in the "Skip to Level" box and click the Go! button.

This soundtrack for this original Tetris game is "Korobeiniki," the original Tetris theme song, of course. If you prefer not to listen to the song, click the speaker button on the game.
