How to play Block Stack
Block Stack is a free Tetris-style puzzle. Differently shaped pieces fall from the top of the board one at a time. Move them left and right, rotate them, and drop them so they fit together. Fill an entire horizontal row and it clears, giving you points and room to keep going. Clear more lines at once for a bigger bonus.
Controls
- Left / Right arrows — move the piece sideways.
- Up arrow — rotate the piece.
- Down arrow — soft drop (faster fall).
- Space — hard drop (instantly place the piece).
- On mobile, use the on-screen buttons.
Tips for clearing lines
- Keep it flat. A level surface gives you more placement options.
- Leave a well. Save one column for long pieces to clear several rows at once.
- Think one ahead. Place the current piece where the next one will also fit.
