Stack Tower

What is Stack Tower?

Stack Tower is a one-tap precision arcade game about building upward without losing your nerve. A neon slab moves from side to side above the tower. Stop it while it overlaps the floor below and that overlap becomes your next level; anything hanging over an edge breaks away and falls. Miss the tower completely and the run ends immediately.

Every cut makes the next placement less forgiving, while the slab accelerates as the tower rises. A placement within the perfect zone snaps cleanly into alignment, preserves the entire floor and starts a scoring combo. The result is a simple rhythm game with a strategic tension: chase the center for bonus points, or settle for a safe overlap when the tower gets narrow.

How to play

• Mobile: tap anywhere in the arena. The entire game surface is the control, so there is no small button to hit.
• Desktop: click anywhere in the arena or press Space. Enter also works for keyboard-only play.
• Each successful placement adds one level and awards points for both survival and overlap quality.
• A perfect placement keeps the block at full width and extends your chain. Three clean placements in a row double every point you score, five push the block back out by about 8 percent each, and eight hand back the full starting width.
• An imperfect placement keeps only the shared area, drops the unsupported piece and resets the chain to zero. Every future block uses the new, narrower width until a chain earns it back.
• A total miss ends the run and submits your score and final height.

Scoring

Every placed floor earns 100 base points plus up to 100 precision points based on how much of the block survives. Perfect placements add another 50 points plus 25 points for each step in the current chain, and from the third clean placement onward the whole total is doubled. The score can therefore grow much faster when you repeatedly find the center instead of merely keeping the tower alive.

Height is tracked separately from points in the HUD. Two players can reach the same height, but the cleaner builder will finish with the higher score.

Strategy tips

1. Watch an edge, not the center. Choose the left or right edge of the settled block and tap when the moving edge lines up with it. Comparing two sharp lines is easier than estimating two centers.
2. Learn the return rhythm. The block reverses at the same safe rails. If the first pass feels wrong, wait for the return instead of forcing a risky placement.
3. Width is a loan, not a loss. A large early cut hurts, but it is repayable: five clean placements start widening the block again and eight restore the full starting width. When the tower gets thin, stop playing safe and start the chain.
4. Use sound and haptics as feedback. A perfect placement has a distinct response. Let that cue reinforce your timing rather than looking away from the moving edge to check the combo.
5. Reset after a miss. Stack Tower rewards relaxed, deliberate taps. A rushed first block is often more damaging than a difficult block twenty levels later.

Daily challenge

Daily mode uses one deterministic seed for the movement sequence, so every player receives the same series of starting directions. Your taps still decide the tower shape and score, but the underlying sequence is shared for a fair daily leaderboard.

FAQ

Does Stack Tower work in landscape?

Yes. The play geometry scales to phones, tablets and desktop windows in both orientations. On wide screens the tower remains centered in a focused architectural lane, while the HUD and full-screen tap target stay inside the viewport.

What counts as a perfect placement?

The moving block must stop within a narrow alignment tolerance of the floor below. The game then snaps it to the exact position, keeps its full width and extends your chain toward the three rewards: double points, a wider block and the full starting width.

Does waiting make the game harder?

No. The block keeps moving at the current level's speed and bounces between the same rails. You can safely wait for another pass; speed increases only after successful placements.

Is the game deterministic?

Yes. Movement comes from the platform's logical clock, and seeded direction changes are part of the recorded input replay. The submitted score and final tower can be reconstructed from the session seed and your placement timestamps.
