Stack Tower

Tap when the moving block lines up with the one below it. Perfect stacks preserve width and build a streak.

How to play Stack Tower

A block slides back and forth above your tower. Tap, click, or press Space to drop it onto the block below. Only the overlapping part sticks — anything hanging over the edge falls away, so the tower gets narrower with every imperfect drop. Miss completely with no overlap at all, and the run ends.

Perfect stacks and combos

Drop a block close enough to a perfect line-up and it snaps to the exact width of the one below instead of shrinking, and extends the displayed perfect streak. Each successful block adds one score point. The tower speeds up the higher you go, so a long perfect streak becomes harder to keep alive the further you push it.

Tips to get better at Stack Tower

Watch the moving block's rhythm for a pass or two before tapping, especially right after the game speeds up. Aim for the same edge of the block below each time rather than trying to guess the exact center. A string of "perfect" stacks preserves more width than several misaligned drops, so it's often better to slow your mental pace and time each drop carefully.

Frequently asked questions

What happens when I miss completely? If there's no overlap at all between the falling block and the one below it, the tower collapses and the run ends.

Does a small miss end the game? No — a partial miss just trims the block to the overlapping width and play continues; only a complete miss ends the run.

Is there a maximum height? No — the tower can grow as tall as your precision allows, and the game gradually speeds up as you climb.

Stack Tower practice guide

Protect width before chasing the combo display

A moving block must overlap the top of the tower. An imperfect drop trims the overhang, leaving a narrower surface for the next block. A near-perfect drop snaps to the previous width and extends the displayed perfect streak. The score counts successful blocks: the streak indicator is not a separate points multiplier in this version. Keeping width is valuable because it makes later drops less demanding.

A small trim changes the next target

Imagine a supporting block is one hundred units wide. If the next block overlaps only eighty units, the new top becomes eighty units wide. The lost twenty units do not return on the following drop. A perfect alignment can preserve that eighty-unit width, but it does not restore the original hundred. Use the same visible edge as a reference instead of recalculating the centre during every pass.

A focused practice session

  1. Watch one pass to learn the moving block’s pace before dropping.
  2. Choose a consistent edge to line up and notice whether your usual mistake is early or late timing.
  3. As the tower narrows or speeds up, aim to preserve the remaining width rather than making rushed recovery taps.

What to keep in mind

Tap, click or press Space to drop. A complete miss, or overlap too small to support the next block, ends the run. Each successful block adds one score point; a long perfect streak helps by retaining width and displaying your consistency.
