Sand does not mix
The top layer only slides onto its own color, or into a jar with room and nothing in it — and it travels whole, all at once.

Why Silto
600 levels the game already solved
Each level was generated and then solved by the game itself before it was allowed to exist. A way through is always in there, waiting to be found.
One level of the day for the whole planet
The day's puzzle is identical for every player. Compare your pours with the par, keep the streak standing, and show a card that gives nothing away.
Rewinding is free
Take the pours back as far as you like: no coin, no ad, no question asked. Nothing here refills, expires or hurries you.
The climb is gentle on purpose
Lighter levels are woven between the hard ones so progress never turns into a wall. Match the par and the level gives back three stars.
Symbols mode
Every color gets a glyph of its own, on the board and on the shared card, so the puzzle stays readable whatever colors you see.
A plane, a tunnel, one bar of signal
Silto never asks for a network, an account or an e-mail. Levels, statistics, stars and the streak are kept on the phone itself.
How it works
- 1
Tap a jar to pick it up, then tap another jar to pour into it.
- 2
Sand pours only onto the same color or into an empty jar, and the whole block moves at once.
- 3
Sort every color into its own jar. Match the par for three stars — undo is free and unlimited.
Frequently asked questions
Does it work in flight mode?
It works in full. Levels, statistics, stars and the streak stay on the phone. When there is a connection, the app also loads ads, the purchase, its settings and anonymous usage and crash statistics.
Is there an account or an e-mail?
Neither. Silto has no sign-up, no login and no leaderboard. Your progress is saved only on the phone; what leaves it are anonymous usage statistics, such as the screens viewed and the levels completed, with no name or e-mail.
Does every level have a solution?
All 600 do. Each one was solved by the game itself before release, so there is a way through even when it is not in sight.
Which ads show up?
A banner at the bottom of the Home, level map, statistics and settings screens; at most one full-screen ad after a level result; and the optional ones you trade for a hint or an extra jar. During play, a banner shows only when it is switched on: in Classic levels, below the board, never covering it. There is never an ad between you and the way out of a stuck level.
How do I take the ads away?
In Settings › Remove ads: a single purchase (US$ 2.99) that switches off the banners and the between-level ads, and comes back on any device using your store account.
Is it playable with color blindness?
It is: symbols mode gives every color a glyph of its own, on the board and on the shared card.
What is new in version 1.1?
A new look of sand and glass: textured sand in the jars, in every pour and in the result stars. The board now sits on the atelier bench, with light that changes with the time of day and a new piece for every 100 Classic levels completed. There is also a new icon, plus fixes such as a warning when the board has no way out.
