Use the on-screen D-pad to move left or right, tap the up arrow to rotate, tap down for a soft drop, and press DROP for a fast hard drop.
Core Rules
- Seven tetromino shapes fall one at a time. Each piece is made of four blocks.
- Complete a full horizontal row to clear it and keep the stack low.
- As you clear lines and place more pieces, the level rises and pieces drop faster.
- The game ends when the stack reaches the top.
Objective & Scoring
Your goal is to clear as many lines as possible and keep the speed under control. Clearing multiple lines at once gives a bigger boost, so aim for clean stacks and four-line clears.
Pro Tips
- Keep your stack flat to avoid hard-to-fill gaps.
- Leave a column open for the I-piece to score a four-line clear.
- Soft drop to fine-tune placement, then hard drop to lock it in.
- Think one or two pieces ahead to avoid panic moves.
