The Seven Tetrominoes

Each piece is made of four squares arranged in different shapes:

• I: Long straight piece (4 blocks in a row)
• O: Square piece (2x2 blocks)
• T: T-shaped piece
• S: S-shaped zigzag
• Z: Z-shaped zigzag

Scoring Tips

• Clear multiple lines: Clearing 4 lines at once (Tetris) gives maximum points
• Keep it low: Don't let your stack get too high
• Plan ahead: Watch the "next piece" preview
• Don't create holes: Avoid leaving gaps under blocks
