Block Drop

Block Drop is a falling-blocks puzzle built the way the arcade cabinets did it: seven shapes, a well ten columns wide and twenty rows deep, and a stack that only ever grows if you let it. Fill a row all the way across and it flashes white and disappears; everything above it slides down and you get a little more room to think.

The tools are all there. A ghost outline shows exactly where the current shape will land, so a hard drop is a decision rather than a gamble. The next three shapes are always on screen, and the hold slot lets you park one for later — the straight piece you are saving for a four-row clear, or the awkward S you would rather not deal with yet. A shape that lands gets a short grace period before it locks, which is just long enough to slide it into the gap you spotted at the last second. Rotations near a wall nudge themselves clear instead of failing.

One row scores a hundred, two rows three hundred, three rows five hundred and four at once scores eight hundred, all multiplied by your level — and the well shakes when you pull it off. Every ten cleared rows raises the level and the shapes fall faster, so a comfortable stack turns into a scramble quickly.
