A crane swings a glass floor over your tower. Tap to drop it, and anything hanging over the edge shears off and falls. Land it dead centre and the tower keeps its width, the chime climbs a note, and the sky turns from night to dawn as you rise.

Stack Tower

Stack Tower is a one-tap timing game about building a glass skyscraper one floor at a time. A crane swings the next slab back and forth above the tower and the whole game is deciding when to let go. Drop it cleanly and the floor sits flush. Drop it late and the overhang is sliced away with a shimmer of glass, so the tower gets a little narrower and the next drop a little harder.

Five perfect drops in a row and the tower grows back a slice of what it lost, so a good run can widen again instead of thinning away to nothing. Every twenty-five floors brings a banner and a new material: glass, frosted, copper, neon, then marble. The camera climbs with you, the sky shifts from deep night blue through peach to full daylight, clouds and a hot-air balloon drift past, birds cross the frame, and the city shrinks into the haze far below.

There are four ways to play. Classic is endless and ends the moment a slab misses entirely. Zen never ends and never lets the tower get too thin, for when you want to build and nothing else. Timed gives you sixty seconds and charges five of them for a miss. Daily Tower gives everyone the same swing pattern for the day. Best floors, best perfect streak and the day's result are kept in your browser, and every run finishes on a results screen that replays your last five drops beside a silhouette of the tower you built.

Tips for Stack Tower

Stack Tower is all about when you let go. Anything that hangs over the edge of the tower is sliced away, so every early or late drop leaves you a narrower floor and a harder next drop. Watch the crane's swing for a moment and release when the slab is right over the tower, not when it is nearly there.

Perfect drops are worth chasing, because five in a row grow back a slice of the width you have lost, and that is the only way to recover from a few poor drops. If the tower has become thin, stop thinking about height and focus on clean placements. New players can start in Zen, which never ends and never lets the tower get too thin, before moving on to Classic, where one slab that misses completely ends the run. In Timed, a miss costs five of your sixty seconds, so accuracy still beats speed there too.

How to play Stack Tower

In Stack Tower you build a glass skyscraper one floor at a time, and the only thing you decide is when to let go. A crane swings the next slab back and forth above the tower. Click, tap anywhere on the screen or press Space to drop it.

If the slab lands squarely on the floor below, it sits flush and the tower keeps its width. Drop it early or late and the part hanging over the edge is sliced away and falls, so the tower gets a little narrower and the next drop a little harder. Five perfect drops in a row grow the tower back by a slice, which is how a run that has thinned out can widen again. Every twenty-five floors a banner appears and the slabs change material, while the camera climbs with you and the sky moves from night towards daylight.

How a run ends depends on the mode you pick. In Classic it ends the moment a slab misses the tower completely. Zen never ends and never lets the tower get too thin. Timed gives you sixty seconds and takes five of them for each miss, and Daily Tower gives everyone the same swing pattern for the day. Each run finishes on a results screen that replays your last five drops beside a silhouette of your tower, and your best floors and best perfect streak are kept in your browser. On a computer, P pauses, M mutes and R restarts.

About Stack Tower

Stack Tower is a one-tap timing game, part of the family of simple stacking games in which everything depends on the moment you let go. It was made by Kiloo and plays in the browser on a computer, tablet or phone with nothing to install.

Because there is only one control, anyone can pick it up in a few seconds, which makes Stack Tower a good fit for younger players and for a short break, while the shrinking floor and the chase for perfect streaks give experienced players something to work at. The four modes suit different moods: Classic for a proper run, Zen for building with no pressure, Timed for a quick sixty-second burst and Daily Tower for a challenge that is the same for everyone that day. What makes it worth coming back to is the way the tower changes as it rises. Perfect drops chime up a scale, the slabs move from glass through frosted, copper and neon to marble, and clouds, a hot-air balloon and birds drift past while the city shrinks into the haze below.

Frequently asked questions

Is Stack Tower free to play?

Yes. Stack Tower is free to play in your browser on Kiloo, with nothing to download and no account to create. Your best floors, best perfect streak and the day's Daily Tower result are kept in the browser you play in.

Can I play Stack Tower on my phone?

Yes. On a phone or tablet you tap anywhere on the screen to drop the slab, which is the only control you need. On a computer you click or press Space, and P pauses, M mutes and R restarts.

What is the Daily Tower in Stack Tower?

Daily Tower gives everyone the same swing pattern for the day, so you all face the same drops. Your result for the day is kept in your browser alongside your best floors and best perfect streak.

What happens every 25 floors in Stack Tower?

Every twenty-five floors a banner appears and the slabs change material, from glass to frosted, copper, neon and then marble. The sky also shifts from night blue to full daylight as the camera climbs with your tower.

How does a run of Stack Tower end?

It depends on the mode. Classic ends the moment a slab misses the tower completely, and Timed ends when its sixty seconds run out, with each miss costing five of them. Zen never ends, so you can keep building for as long as you like.

Is Stack Tower good for kids?

Stack Tower has a single control, a tap, a click or Space to drop the slab, so younger players can start straight away. Zen is a gentle place to begin, because it never ends and never lets the tower get too thin. There is nothing to download.
