Stackfall
Stackfall is a free falling-block puzzle game in your browser. Rotate and drop pieces to complete lines, with a hold slot, a three-piece preview and a ghost that shows where each piece will land. The twist: every eight lines, a piece carries a gravity bomb. When it lands it blasts a hole, and every column above collapses — often setting off chain clears.
Play marathon for a high score, or sign in for online versus: both players get the same pieces, and every multi-line clear sends garbage rows to your opponent, whose board you can watch live beside your own.
