Stair Dismount (also known as Porrasturvat) is a computer game originally made by Jetro Lauha of tAAt. It is a puzzle game where the goal is maximising the damage done to a 3D stickman figure; the player causes damage by applying a force to the figure to make it fall down a staircase.

The stick figure's falls are accompanied by various sound effects — cracks, wails and groans — as it makes its way to the bottom. Stair Dismount uses ragdoll physics, so the figure is very floppy as it falls, like a ragdoll.

The game was first published in Assembly 2002, where it won the first prize in the game development competition.

The newest version, 1.0.3, is available for Microsoft Windows, Mac OS X and Linux.

Stair Dismount for iPhone and iPod touch was released on 25 Nov, 2009[1] (originally announced as Stair Dismount Touch[2]). Later it has been modified to be an "Universal" build to add support for iPad. Subsequently it has also been released for Android devices in June 2011.
