About Moon Stack
Moon Stack is a tower building game all about timing. A friendly UFO swings each new block from side to side above the tower, and one tap drops it. Drop it right on top of the last block for a Perfect drop that clicks into place perfectly straight. Miss the tower, or hang too far over the edge, and the block falls off and costs a heart.
Blocks that land a little to the left or right make the tower lean, and a leaning tower wobbles. A wobble meter shows how close it is to falling, and the animals in the windows get scared when it's nearly over. Drop the next blocks a little to the other side to balance it again, or the whole tower comes crashing down. As it grows, the tower climbs past trees, birds, balloons, clouds and planes, out into space and up to a big smiling Moon.
How to play Moon Stack
- Pick Easy, Medium or Hard and tap Play.
- Watch the UFO swing the block from side to side.
- Tap anywhere, or press Space, when the block is right above the tower.
- Land it exactly on top for a Perfect drop and extra points.
- If the tower leans, drop the next blocks a little to the other side to balance it.

Levels and difficulty
There are three difficulties, each with its own leaderboard. Easy has a slow swing, 5 hearts, a wide Perfect zone and a guide that shows where to drop. Medium swings faster, has 3 hearts and makes the top of the tower glow when you're lined up. Hard swings fast, has a small Perfect zone, no glow and wind high up. On every difficulty the swing gets a little faster as the tower grows. Every block is 10 points, a Perfect drop 20, and Perfect drops in a row give up to 50 more each. The game ends when the hearts run out or the tower falls down.
Tips for parents and teachers
- Watch a couple of swings before tapping: the block is slowest at the ends and fastest in the middle.
- Talk about why a leaning tower falls, and how blocks on the other side balance it.
- Start on Easy, where a guide shows exactly where to drop.
Moon Stack questions
Is Moon Stack hard?
On Easy the swing is slow and a guide shows where to drop, so children of 6 can build tall towers. Hard is a real challenge for older children and grown-ups.

Yes. Press Space, Enter or the down arrow to drop a block.

No. It plays right in the web browser on phones, tablets and computers. You can also add it to your home screen like an app.
Does my child need an account?
No. Anyone can play straight away. A free Wizzymoon account is optional: it saves progress across devices and puts scores on leaderboards.

Yes. There are no ads, no chat and no links to other sites. Other players only see a username on a leaderboard, and friends added with a secret code can also see when you're online.
