Tower Balance works the physics-puzzle sweet spot where every piece you add is both progress and peril. Build too fast and the whole thing sways; build too cautiously and you go nowhere. The genre thrives on that wobble, on the held breath between a bold placement and the moment the tower decides whether to forgive it.

It is free in the browser with no download, which makes it dangerously easy to say yes to one more level. Read the weight, respect the wobble, and place with a steady hand. When you want more brain-and-timing challenges, Pogglo has a full shelf of puzzle games ready to go.
