How do you score in Block Stacker?

You score by completing full horizontal lines, which then clear from the board. Clearing several lines at once is worth more, so setting up multi-line clears pays off.

How do I rotate and drop pieces?

Use the up arrow or W to rotate, left and right to move, the down arrow to soft-drop, and Space to hard-drop. On mobile, on-screen buttons handle all of these.

Yes. As you clear more lines the level rises and pieces fall more quickly, so the challenge ramps up the longer you survive.

When does the game end?

The game is over when a new piece can no longer fit at the top of the board because the stack has grown too high. Keep the stack low and flat to last longer.
