Stack Tower

Drop each sliding block right on top and build to the stars

Build one floor higher

Only the part that lands on the block below stays. Line it up for a Perfect, and three Perfects in a row start to widen the block again.

How do you play Stack Tower?

Tap at the right moment to drop the sliding block onto the one below and stack the tower as high as you can. It is a one tap arcade game, and your score is the number of floors you build.

Blocks slide in from the back left and the back right on alternate floors. The tilted 3D view shows the top and sides of every block, and the colors shift through the rainbow floor by floor.

What happens when a block is off?

Your dropWhat happens
A little offThe overhang is sliced off and tumbles away. Only the overlap stays, so the next block is that much narrower.
Spot on (Perfect)Nothing is cut and "Perfect!" pops up. From the third Perfect in a row, each one widens the block a little, up to its starting size.
Missed completelyThe whole block falls and the game ends. The camera pulls back to show the tower you built.
Higher floorsBlocks keep getting faster until about floor 60, then the speed stays at its maximum.

Why does the sky change color?

As the tower grows, the sky turns from daytime to sunset, then dusk, then a starry night. The color tells you roughly how high you are, and once stars appear you are doing very well.

Tips for a taller tower

  1. Watch the edges. Timing the block's edge against the corner below is easier than judging the center.
  2. Go for Perfects while the block is wide. A narrow block leaves no room for mistakes, so bank your Perfects early.
  3. Win back width with streaks. From the third Perfect in a row the block grows, so slow down and find the rhythm when it gets thin.
  4. Play by rhythm. Blocks move back and forth at a steady pace, so tapping to the beat works better than chasing them with your eyes.

Frequently asked questions

Is Stack Tower free?

Yes. Play it free right on this page with no download or sign up, on computers, phones and tablets.

How is the score counted?

Your score is the number of floors you stack. A block that was trimmed down still counts as a full floor.

How exact does a Perfect have to be?

If the block lands within 4% of the starting block width from the one below, it counts as Perfect. It snaps into place and keeps its full width.

Can a narrow block get wider again?

Yes. After three Perfects in a row, every further Perfect widens the block a little. It never grows past its starting size.

Does it keep getting faster?

Blocks speed up as you climb, reach top speed around floor 60 and stay at that speed after that.

When does the game end?

When a dropped block does not overlap the block below at all, it falls off and the game is over.
