Question 1

How do you play Tetris?

Accepted Answer

Use the left and right arrow keys to move the falling block, the up arrow to rotate it, the down arrow to soft-drop faster, and the space bar to hard-drop. Fill complete horizontal rows to clear them and score points. The game ends when the stack reaches the top of the board.

Question 2

What are the 7 Tetris pieces (tetrominoes)?

Accepted Answer

The seven tetrominoes are I, O, T, S, Z, J and L. Each is made of four squares. The I-piece clears the most rows, the O-piece is a 2x2 square that never changes shape when rotated.

Question 3

Does Tetris speed up as you play?

Accepted Answer

Yes. Every 10 lines you clear raises your level, and each level increases the falling speed. The higher your level, the faster pieces drop and the harder the game becomes.

Question 4

Can I play Tetris on mobile?

Accepted Answer

Yes. Tap the left or right half of the board to move, swipe down to soft-drop, swipe up to rotate, and tap the center to hard-drop. On-screen buttons are also provided.
