Stack Attack is a fast-paced falling-block puzzle where you steer colorful falling shapes, spin them into perfect fits, and clear full rows to survive.

How to play Stack Attack

Tips & tricks
- Rotate blocks before they reach the bottom by pressing the up arrow—early rotations give you more placement options than waiting until the last second.
- Use the hard drop (Space) when you're sure of a spot; holding the down arrow for a soft drop brings a piece down faster while you can still slide it. Neither buys thinking time, so decide while the piece is still high.
- Earn bombs every 8 cleared lines and use them to blow out the bottom row when your stack gets dangerously high—this gives you breathing room to keep clearing lines.
Frequently asked questions
How do you play Stack Attack?
Use arrow keys to move blocks left and right, press up to rotate, down to soft drop, and Space for hard drop. Clear a full row across the grid to score points and level up.
What are bombs and how do you use them?
Bombs are power-ups you earn every 8 cleared lines (the 💣 count shows in the score bar and on the bomb button). Press B or the bomb button to use one—it clears the bottom row and shifts your stack down, giving you space to keep playing.
