What is this?

Terrarium is a falling sand game with a garden in it. Draw sand, soil, water and stone with your finger or mouse and they behave like the real thing: sand piles up, water flows downhill and soaks into soil. Drop seeds onto damp soil and they sprout, grow leaves and open into flowers. Turn on the rain and leave it running. It works in any browser, on phones too.

Questions

What is a falling sand game?

A sandbox where the screen is a grid of tiny particles, each made of one material. Simple rules — sand falls and piles, water flows and spreads — add up to surprisingly lifelike behaviour, so you can build, pour and experiment with no goal at all.

How do I make the seeds grow?

Seeds sprout on damp soil. Pour water onto the soil (or switch on the rain), then drop seeds on top. A sprout grows upward, puts out leaves, and opens a flower when it's done.

Can I start over?

Yes — “New terrarium” resets the scene to a fresh bed of soil with a few seeds already planted. Your all-time flower count stays in your browser.
