One new puzzle a day 
Beat the par 
Pour. Think. Undo for free. 
Symbols for every eye 
600 levels, all solvable 
Your streak, your stats
Why Silto
No lives. No energy. No timer.
Play as much as you want, whenever you want. Nothing recharges, nothing runs out, nothing counts down.
Undo is free and unlimited
Take back one move or twenty. Undo never costs coins, never plays an ad, never asks.
600 levels, every one guaranteed solvable
Each level was generated and solved by the game before it reached you, so there is always a way through.
Works offline. No sign-up.
Silto runs entirely on your phone. No account, no login, no connection needed.
Symbols mode for color-blind players
Turn on symbols and every color also carries its own glyph, on the board and on the shared result.
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 offline?
Yes. Silto runs entirely on your device: levels, the Daily challenge, statistics and streak all stay on your phone. The connection is only used by ads and by the purchase.
Do I need an account?
No. No account, no login, no e-mail. Nothing you play is sent to Losenvo.
Are there ads?
One ad between levels, after the result, plus optional ads you can choose to watch for a hint or an extra jar. There is never an ad between you and the way out of a stuck level.
How do I remove the ads?
Settings › Remove ads: a one-time purchase (US$ 2.99) that removes the interstitials forever. It can be restored on another device with the same store account.
Is it playable with color blindness?
Yes. Symbols mode adds its own glyph to every color, on the board and on the shared result, so the puzzle stays readable whatever colors you see.
