BlockFall

In BlockFall pieces do not stay solid. The moment a piece lands it crumbles into thousands of grains, and the sand flows down, slides off diagonally and fills everything it can reach. What wins is not a tidy placement but the right drop point.

Four modes:

Ranked — the main mode. Connect sand of one colour from the left wall to the right and the whole bridge burns away. Longer streaks raise the multiplier.

Campaign — 50 levels with goals and obstacles: pillars, funnels, narrow shafts, offset necks and fields with two or three target zones. Gaps tighten, spare moves run out.

Rush — the same ranked play, but the piece falls on its own and keeps accelerating.

Classic — a 10x20 well, a seven piece bag, rotation with wall kicks and line clears.

Records are saved and every mode has its own leaderboard.
