Stack Odyssey is a one-tap tower builder that turns a simple rhythm into a climb through all of human history - and then keeps going.

A block swings from a crane. Tap to drop it. Land it flush and you score a PERFECT and the tower holds steady. Land it badly and the whole structure starts to sway, making the next drop harder than the last. Fill the screen and your tower carries you into the next era.

27 ERAS, ONE CONTINUOUS CLIMB
Begin in the Stone Age and build up through Ancient Egypt, Greece, Rome, China, the Maya, medieval Europe, feudal Japan, the Vikings, the Renaissance, the Age of Exploration, the Industrial Revolution, the Wild West, the roaring 1920s, a modern metropolis and a neon cyberpunk skyline. Then keep going: into orbit, to the Moon, Mars, the asteroid belt, the outer planets, interstellar space, an alien world, a nebula, and finally the Milky Way Core.

Every era is built from scratch - its own art, its own crane mechanism, its own soundscape. You always know how far you have come by what is around you.

EASY TO PLAY, HARD TO MASTER
One tap is the whole control scheme. There is nothing to learn and no tutorial to sit through. Mastery is all timing: chain perfect drops to keep the tower calm, or scramble to recover when it starts swaying.

SMALL DOWNLOAD, NO WAITING
