Stack blocks. Defy gravity. Beat your best. An adaptive algorithm designs every round to match your skill — you'll always feel challenged, never cheated.
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.
Every block obeys gravity, friction, and momentum. An adaptive algorithm designs each round to match your skill in real time. 28 block shapes, 3 tiers of challenge.
