Stack game

Tap, click or press Space to drop each block on the tower.

How do you play the stack game?

A block slides over the tower; tap, click or press Space to drop it. The part that hangs over the edge falls off, so the next block is smaller. Drop a block almost exactly on the one below for a perfect drop that keeps its size. A block that misses the tower ends the game.

How to play the stack game

  1. Press Play. A block slides over the tower, from one side to the other.
  2. Tap, click or press Space to drop it. The part that hangs over the edge falls off.
  3. The next block is as big as what is left, so each miss makes the tower narrower.
  4. Drop a block almost exactly on the one below for a perfect drop: it snaps into place and keeps its size.
  5. Three perfect drops in a row make the block grow back a little. A block that misses the tower ends the game.

Each block counts one point. The blocks slide a little faster as the tower grows.

Tips for a taller tower

  • Watch the edge of the block below, not the moving block, and tap as the edges line up.
  • Find a rhythm. The blocks slide at an even speed, so the right moment comes at an even beat.
  • A narrow tower is hard but not lost: perfect drops in a row make it wider again.
  • On a Chromebook, press Full screen, and use Space: a key is faster than a click.

Questions

What is a perfect drop?

A drop that lands almost exactly on the block below: off by no more than 3% of the width of the first block. The block snaps into place and keeps its size. Three perfect drops in a row make the block grow back a little.

Does the stack game get faster?

Yes, a little at each block, up to a top speed. The blocks slide at an even speed, so you can find a rhythm.

Is the stack game unblocked at school?

It is a normal web page on lifesim.com, with no download and no sign-up, so it opens on most school Chromebooks. We can't promise that every school filter allows it.

How do I share my score?

After a game, press Copy link, or Share on a phone. The link shows your friend your height to beat, with the same colors for their tower.
