Tetris is a very popular block game that first started in the 80's. If you don't know how to play, now's a good time as any, read on.

Steps

Get a Tetris game to play. Tetris is available on almost all electronic mediums, you can try it on your computer; a GBA or Nintendo DS work too.
Start the game on the lowest level. As you play the game levels will go up, but you need to start at a low level to help you practice.
Move the tetrominoes left and right with the arrow keys or buttons. Try to move the tetrominoes to get them to move together.
Understand the different tetrominoes. In traditional Tetris games there are seven different types of tetrominoes:
- I-blocks are useful for getting 'Tetris', that is competing four lines at once.
- O-blocks for filling large gaps.
- L-blocks for filling medium-sized holes.
- J-blocks face the opposite direction as L-blocks.
- S-blocks for filling small holes.
- Z-blocks face the opposite direction as S-blocks.

- T-blocks are also for filling small holes.
Use the action button to rotate the tetrominoes to fit holes. These can range from the A button, X button, space bar, enter key or even something else, depending on your particular Tetris game.
Complete lines to gain points and raise the level. The more lines completed at once, the more points gained. Completing the maximum number of lines at once, four, is known as a 'Tetris' and can only be pulled off with straight, long rectangle tetrominoes.
Check upcoming pieces and plan for them. This will become easier the more you play, don't rush yourself.

You may easily become addicted and spend all your time playing Tetris, resulting in your to-do-list being neglected.
