How To Play

1. Press Start tower. A block moves across the top floor.
2. Press Drop block, tap the tower, or use Space when it lines up.
3. The overlapping section becomes the next floor. Every piece outside the overlap is cut away.

Build and finish

Movement gets faster with each floor. The new block has the same width as the overlap you kept. A drop with no overlap ends the run; completing 32 floors wins. Best height counts successful floors above the starting base.

Pace and pause

Choose Gentle or Steady before starting. Gentle moves more slowly. Press Pause or P to stop, then Resume to continue. Leaving this tab pauses an active tower.

Replay and saving

Restart tower ends an active run after confirmation. Your best height and pace stay saved. The moving tower is not restored after reload; a fresh tower starts. A dropped block cannot be undone.

Original game

Skycairn uses its own stone-floor graphics and timing rules. The general height-stacking goal is described by Ketchapp’s developer listing. The exact overlap and progressive-speed rules above belong to this game.
