In Lemmings: The Puzzle Adventure, the Stairs instruction transforms a lemming into a Builder who then creates a diagonal staircase by stacking 9 bricks across a tile.
The Stairs instruction allows lemmings to reach higher places. It can be placed on any empty space and is consumed by the first lemming to reach the instruction.
- Stairs costs 1 energy to assign
- Stairs cannot be built directly below any blocks, traps, or ceiling
- Stairs can be linked with other lemming structures (i.e. other stairs or bridges) to form complex structures (for example, stairs can be built under a bridge to link both structures)
- Builders pause for a short while after completing the stairs unless they immediately trigger another build instruction (i.e. Stairs or Bridge)
- Stairs can be used to change the direction of the Builder
- Both ends of the stairs cause a slight protrusion to neighboring tiles which might make the Umbrella trick ineffective
- A completed staircase may only be destroyed by explosions, either using the Destroy, Dynamite, or Rocket instructions or by detonating explosive blocks
- A completed staircase can withstand any amount of falling rocks including falling piercing rocks
- Stairs reflect laser beams
- A group of lemmings closely bunched together will sometimes slow down to queue up/down the stairs
Recurring bugs[]
- Main article: Lemmings: The Puzzle Adventure/Bugs
- Lemmings sometimes fall through the steps of stairs
- Lasers hitting the underside of stairs sometimes still kill the lemmings on top of it
- After completing the stairs, the Builder may ignore the instruction in front of it and just fall
