About Stack Tower
Stack Tower is a one-input timing game about stacking a tower without letting it taper away to nothing. A block slides horizontally above the tower and you drop it; whatever overhangs the block beneath is sliced off and lost, and the width that remains is what the next block gets to land on. There is no way to widen the tower again, so the whole game is a slow contraction and the only question is how carefully you manage it. The first block is 200 pixels wide and the run ends the moment the tower narrows past 10, which is 5% of where you started. Precision is scored rather than merely survived. Landing within 5 pixels of perfect alignment counts as a perfect stack, worth 25 points instead of 10, and consecutive perfects build a combo that multiplies every block up to ten times - so a perfect at combo ten is worth 250 while an ordinary sloppy block is worth 10. A single imperfect drop resets the combo to zero and takes the multiplier with it. The block also speeds up as you climb, starting at 2 and rising by 0.15 per block until it caps at 8 around forty blocks up, which is where most runs end.
How to Play Stack Tower
Tap, click or press space to drop the moving block. It lands where it was when you released, the overhang is cut away, and the next block starts sliding at the new narrower width. Land within 5 pixels of perfectly aligned and the drop counts as perfect: no width is lost and the block scores 25 rather than 10. Perfect drops in a row build a combo multiplier that rises to ten and multiplies everything, so the same perfect block is worth 250 at full combo. Any imperfect drop resets that multiplier to zero. Block speed starts at 2 and increases by 0.15 with every block placed, reaching its maximum of 8 at around forty blocks. When the tower narrows below 10 pixels the run is over.
Stack Tower Tips and Strategy
- Release early, not on the mark. Input takes time to register and the block is moving the whole way, so aiming at where the block will be beats aiming at where it is
- The combo multiplier caps at ten and dies on one miss, which makes a long clean run worth more than every other consideration combined - a perfect at full combo is 250 points against 10 for a scrappy one
- Perfect drops cost no width at all. A run that is genuinely all perfects never narrows, so the width you have left is a direct record of how many you have missed
- Speed rises 0.15 per block from a base of 2, so block forty moves four times as fast as block one. Your timing has to shift steadily earlier the whole way up, not just at the end
- Once the tower is narrow, stop trying for perfects. A safe hit that keeps 8 pixels alive beats a greedy one that leaves 3
- The floor is 10 pixels out of an opening 200, so you can afford to lose 95% of your width across the run - but losing it early leaves nothing to work with when the block is at full speed
- There is a 100ms input debounce, so a double tap will not place two blocks. If a drop seems not to register, it did - watch the tower, not your finger
Stack Tower FAQ
Is Stack Tower free to play?
Yes. Stack Tower is free on Weekly Arcade with no downloads, no ads and no account needed. Signing in adds leaderboard submission and achievements.
How does scoring work in Stack Tower?
An ordinary block scores 10 points and a perfect one scores 25. Both are multiplied by your combo, which rises by one per consecutive perfect drop and caps at ten. So a perfect block at full combo is worth 250 points, and any imperfect drop resets the combo to zero.
What counts as a perfect stack?
Landing the block within 5 pixels of exact alignment with the one below it. A perfect drop loses no width at all and scores 25 instead of 10, which is why a genuinely perfect run never gets narrower.
When does the game end?
When the tower's width falls below 10 pixels. The first block is 200 pixels wide, so you can lose 95% of your starting width before the run ends - but every imperfect drop is permanent, because there is no way to make the tower wider again.
Does the game get faster?
Yes, and predictably. The block starts moving at speed 2 and gains 0.15 with every block placed, capping at 8. That maximum is reached at about forty blocks, which is where most runs finish.
Can I play Stack Tower with a keyboard?
Yes. Space drops the block, and tap or click does the same thing on touch and mouse. There is a 100 millisecond debounce on input so a single press cannot place two blocks by accident.
Does Stack Tower work offline?
Yes. Once the page has been cached the game runs with no connection. Scores submitted while offline are not recorded on the leaderboard, which needs a connection and a signed-in account.
