Block Stack - Tower Physics

Block Stack is a physics stacking game with one rule: don't let anything fall. Drag blocks from the dock, drop them onto your tower, and stack as high as you can.

REAL PHYSICS, REAL TENSION

Every block obeys gravity, friction, and momentum. No grids, no snap-to guides — just you, the blocks, and the laws of physics. A careless placement can send your entire tower into a slow, agonizing lean.

THE GAME THAT LEARNS HOW YOU PLAY

An adaptive algorithm watches your tower — scanning its shape, measuring its tilt, tracking how well you play — and designs each round to match your skill level in real time. You'll never notice it working. You'll just feel like every round matters.

28 BLOCK SHAPES, 3 TIERS OF CHALLENGE

Start with simple squares and dominoes. As your tower grows, L-shapes and trominos enter the mix. Push past 30 blocks high and face S-pieces, Z-pieces, T-pieces, and the dreaded I-bar.
