Stack Blitz is a precision game dressed up as a building game. A slab slides back and forth above your tower. Drop it, and whatever lands on the floor below stays. Whatever hangs over the edge is sliced off and falls away. The next slab is only as wide as what survived, so every mistake is carried upward for the rest of the run.
- Score is 120 points per floor plus a small bonus for the width of your final floor.
- A near-perfect drop snaps into place and keeps the full width of the floor below.
- The slide speeds up as the tower grows, and the run ends when a drop barely touches or misses the tower.
- Height is the score. Width is the resource that lets you keep gaining height.
Tap or click anywhere, or press Space or Enter, to drop the slab. That is the only input. The game is designed for a portrait screen, which gives the tower room to climb, so hold your phone upright. On the start screen you can choose Easy, Normal or Hard, which changes how fast the slabs slide and how quickly that speed rises. The scoring is identical on all three, and ranked runs such as daily challenges are played on Normal.
Your first tower
- Step 1: Watch one full sweep
Let the first slab travel across once so you can see its speed.
- Step 2: Line up the edges
Drop when the leading edge of the slab meets the edge of the floor below.
- Step 3: Expect a change of direction
Each new slab enters from the opposite side of the previous one.
- Step 4: Keep going
The run continues until a slab lands with almost no overlap or misses entirely.
score = floors × 120 + leftoverWidth- Each floor placed
- 120 points
- Leftover width bonus
- Up to 92 points, based on how wide your top floor is
- Perfect drop
- No width lost; the slab snaps onto the floor below
- Missed or barely touching drop
- Run ends
The width bonus is small. Even a top floor at full width is worth less than one extra floor. That tells you how to think: width matters because it gives you margin for future drops, not because of the points it adds at the end.
If your slab lands almost exactly centered on the floor below, with the same width, the game treats it as perfect. It snaps neatly into place and nothing is sliced. Your current streak of perfect drops shows in the run summary. Perfect drops do not add points directly, but they are the only way to stop the tower from narrowing, which makes them the most valuable habit in the game.
Two pressures build at once. The slide speed rises a little with every floor until it reaches a cap. At the same time, any slicing narrows the slab, and a narrow slab gives you a smaller window to land on. A drop with only a sliver of overlap ends the run, so a very narrow tower is one small error away from the end.
Pros
- Early floors are slow, so this is the time to build perfect drops
- A wide tower absorbs a slightly late drop without ending the run
- The slab always slides at a steady speed, with no sudden jumps
Cons
- Speed rises with height, so late floors leave less reaction time
- Width lost early is never recovered
- A near miss with a sliver of overlap still ends the run
- Spend the slow early floors chasing perfect drops. That is where they are easiest.
- Accept a small slice rather than waiting for a perfect moment that might pass.
- Find a rhythm. The slab bounces between the same edges, so its timing is predictable.
- When the tower narrows, focus on overlap. Any landing is better than a miss.
- Do not rush the drop as the speed rises. Let the slab come to you and drop on the edge.
- Dropping as soon as the slab appears instead of waiting for alignment.
- Watching the whole tower instead of the one edge that matters.
- Trying to correct a previous slice by dropping deliberately off-center.
- Playing on a landscape screen where the tower has little room to show.
Your tallest tower is the one that counts on the leaderboards. Stack Blitz's bronze, silver and gold achievements step from finishing a run to a tower that takes practice to a genuinely tall one, and a long run of perfect drops is the surest way there. If you enjoy precise, unhurried puzzles, Tile Shift rewards the same patience, and Match Prism offers a faster kind of pattern reading.
What ends a Stack Blitz run?
A drop that misses the tower or overlaps it by only a sliver.
Do perfect drops give extra points?
Not directly. They keep the full width, which keeps future drops easier and the run going.
Does difficulty change the score?
No. Easy, Normal and Hard change the slide speed, but the formula is the same. Ranked runs are played on Normal.
Why does the slab change direction?
Each new slab enters from the opposite side of the previous one, so you alternate between timing a slab moving right and one moving left.
