How to Play

Arrange falling blocks (tetrominoes) to create complete horizontal lines. When a line is completed, it disappears and you earn points!

Scoring: Clear multiple lines at once for bonus points. The game speeds up as you advance through levels.

Tip: Use the "Next Piece" preview to plan ahead. Keep your stack low and avoid gaps!
