Climb 999 floors. One ball, seven bands, no second chances. Don't look down.
One ball. Nine hundred ninety-nine floors. Don't look down.
999 Stairs is a physics climbing game: roll a ball up a tower of stairs that grows harder with every floor. Steer with a floating stick, hop gaps when the climb opens up, and survive collapsing steps, slick surfaces, wind, and paths that lie.
Seven material bands reshape the tower as you rise — stone cellar, timber attic, iron foundry, glass atrium, storm spire, void scaffold, and the crown. Each band changes the light, the texture under your feet, and what can kill you.
Unlock new balls as you climb. Reach a floor, earn a skin, wear it from the locker. Progress checkpoints save your place; falling sends you back to the last one.
Sound respects the silent switch. When the phone is muted, the game is quiet.
