Sandfold

A rangoli puzzle for Android

Pour the powder. Mind the chalk.

Sandfold is a rangoli puzzle for Android. Hold a finger on a stencil and coloured powder pours, piles and spreads. Chalk lines hold it back only up to a height, so pour too long and it spills into the next shape. Each colour has a limited pot. It’s free, with no ads and no account, and it works offline.

Sandfold pour screen on the Eight-petal lotus, mirrored eight ways: rani pink powder pours into all eight petals at once and their chalk outlines glow amber as they near the top.

Pour, watch, lift

Press and hold to pour, drag to move the stream, and lift to stop. As a shape’s powder nears the top of its chalk, the line glows like a lamp. On small mirrored shapes a spill can follow at once, or come with no glow, so pour in short taps. Undo gives a spilled pour back.

The rules, the states of a shape and the game’s limits are in How it works.

One stream, many petals

From chapter 2 your pour is mirrored: four or six streams in the Mirror chapter, eight in Eight Ways, and four or eight in Threshold, all from one finger. One stream fills many petals at once, and so does one spill. Every stream draws on the same pot, so an eight-way pour empties it eight times as fast.

Four chapters of ten rangolis

  • Chapter 1

    First Petals

    Pour, chalk, pots and spill, with no mirror.

  • Chapter 2

    Mirror

    Your pour mirrored in four, then six.

  • Chapter 3

    Eight Ways

    Mirrored in eight, with thin chalk lines.

  • Chapter 4

    Threshold

    Large kolam frames and tight pots.

Each chapter opens when you have finished seven rangolis of the one before.

A rangoli every day

The Daily rangoli is the same for everyone on the same date, going by the date on your phone. It is built on your phone, so it needs no internet. Missed a day? Tap any earlier day of this month to pour it. There are no streaks, no lives and no timers.

Your courtyard

Every finished rangoli is laid at a doorstep with a lit diya, and a missed day is plain floor. Finish every day of a month and it becomes a framed month doorway. A neat finish, with not a grain over the chalk, earns a marigold garland. You can share any finished rangoli as an image.

Diwali, any day of the year

The Diwali set of ten rangolis, from One diya to a ring of marigold and mango leaves, can be poured any day. In the Diwali days it moves to the top of Today, the app is dressed with rows of lit diyas, and a rangoli you finish then carries a dated keepsake frame.

Geometric patterns only

Patterns are built from dots, petals, lotuses, leaves, kolam dot grids and lamps. There are no deities and no religious symbols to spill on, and every stencil and its name were reviewed before release.

Calm by design: no ads, no account, offline

Sandfold has no ads, no in-app purchases, no account, no analytics and no notifications, and it has no internet permission, so it works anywhere. There are no timers, lives or streaks. Your courtyard, progress and settings are kept on your phone, and Android can copy them to your own Google account backup and to a new phone.

Play your way

  • Light and dark themes; the rangoli floor keeps its colours in both.
  • A pattern mark on every powder colour, so no shape depends on colour alone.
  • With TalkBack, every shape is named with its colour and how full it is, with actions to pour a little or more, undo and sweep.
  • On a keyboard or D-pad, move between shapes and pour with Enter.
  • Sound, vibration and reduced motion each have their own switch.
  • Undo, redo, sweep and hints are free.
  • The Eight-petal lotus with its yellow haldi background and part of the blue border poured, and eight pink streams falling into the petals from one finger.
  • After a long pour, pink powder has crossed the petals’ chalk; the dashed chalk and the status line say the background is muddied by another colour and that Undo gets that pour back.
  • A finished Eight-point star in yellow, blue and orange with the diya below it lit, the message “Complete. The diya is lit.” and a link to see it in the courtyard.
  • The Today screen in the Diwali days: bunting and lit diyas, today’s rangoli ready to pour, and the Diwali rangolis set featured with One diya, Three diyas and Ring of eight diyas.
  • The courtyard with a month doorway of 31 finished Daily rangolis for October 2026, and below it finished rangolis including two with Diwali 2026 keepsake frames.
  • The courtyard in the dark theme: finished rangolis on stone tiles with lit diyas, marigold garlands on neat finishes and Diwali 2026 keepsake frames.
