Quick answer
What is Skyward Stack?
Skyward Stack is a one-button tower builder. A block slides back and forth above your tower, and you drop it with a tap, click, Space or Enter. Any part that overhangs the block below is sliced off, so every sloppy drop leaves a narrower tower. The run ends the moment a block misses the tower entirely.

How a run works
- Tap, click or press Space or Enter on the start screen to begin. A block starts sliding across the top of the tower.
- Drop the block when it sits over the tower. The overhanging edge is trimmed away and falls off the screen.
- Land almost exactly on the block below and it snaps into place as a perfect drop, worth 2 points instead of 1.
- If a block lands with no overlap at all, the run ends. Tap again after the game-over panel appears to restart.
Controls
- Tap or click
- Drop the sliding block, start a run or restart after game over
- Space or Enter
- Same as a tap, for keyboard play
- Tap a theme tile (start screen)
- Pick a theme you have unlocked
What changes as the tower grows
- Consecutive perfect drops widen the block again, up to its original width.
- Blocks slide faster as the tower gets taller, up to a speed cap.
- Four themes: Classic, then Neon, Wood and Ice, which unlock at 25, 50 and 100 points in the default setup.
- The sky changes colour as you climb, and your best score is saved on this device. A top-10 leaderboard and a share button are included.
Stacking tips
- Watch one full slide before you commit; the block passes over the tower on every pass, so there is no reason to rush the first drop.
- Aim for the middle of the gap rather than the edge. A slightly off drop costs width, and width is your only buffer.
- Chain perfects when you can: after two in a row the block starts regaining width.
- When speed picks up, tap on rhythm instead of reacting to the block's position.

Skyward Stack FAQ
What counts as a perfect drop?
A drop that lands within a few pixels of the block below. It snaps into alignment, scores 2 points and starts a combo counter.
What ends the game?
Dropping a block so that it does not overlap the tower at all. Partial overlaps just trim the block.
How do I unlock the other themes?
Reach the required score in a run: by default 25 points for Neon, 50 for Wood and 100 for Ice. Unlocked themes are chosen from the tiles on the start screen.
Is my best score saved?
Yes. Your best score and chosen theme are stored in your browser on this device.
