Seamfall: Falling Block Puzzle

Eleven columns. Twenty-one rows. Everything you stack is eventually going to give way.

Seamfall is a falling block puzzle about going deeper. Shards drop down a mineshaft, you fit them together, and a full row — a seam — collapses under its own weight. It is the classic clear-the-line stacking puzzle, rebuilt for a phone held in one hand. Clear enough seams and the Depth ticks over, the shaft speeds up, and the Feed stops playing fair.

PAST DEPTH 5, IT CHANGES

Most block drop games hand you the same seven pieces forever. Seamfall does too — at first. Then the shaft starts sending things that do not fit: three-cell Chips and Splinters, five-cell Talons, Clefts and Spines. They arrive without warning and they ruin a tidy stack. Learning to survive them is the game.
