Gravity Desert Flip

A falling-sand puzzle where you tilt your phone and the whole desert pours the other way

Gravity Desert Flip is a falling-sand puzzle game by Rui Codex for Android. Sand pours from the ceiling and piles up like real sand; a colour that touches both side walls clears, and turning the phone flips gravity so every grain flows toward the new floor. It is free, plays offline and has no forced ads, with optional videos and a one-time Desert Patron purchase.

About Gravity Desert Flip

Gravity is a direction you control. Drag the nozzle along the ceiling and hold to pour, and the heap grows, slides and settles grain by grain. When one colour touches both side walls, it clears. Turn the device, or tap the flip button, and the whole desert pours toward the new floor in one of four directions, so a single flip can join two heaps you poured a minute ago. A slight lean makes the sand drift sideways, and jokers, bombs, wet sand and rock each change how a heap behaves.

The Caravan Road holds 120 puzzles across six desert worlds, 20 in each, with goals such as clearing a single colour or building a chain, star chests to open and a par to beat. Sand of the Day adds one new puzzle every day, the same for every player. Endless mode runs until the sand reaches the nozzle, with three to six colours as you climb, the Daily Run gives everyone the same 60 batches with three attempts a day, and Time Attack asks for the highest score in two minutes.

Every grain you clear falls into your pouch and can be poured, layer by layer, into 30 sand bottles. Glass, earned by playing, unlocks themes, vessel frames and sand trails, and 40 achievements and Dune Markers add long goals. There are no banners or interstitials and every video is optional; Desert Patron is one purchase, not a subscription, and nothing you buy changes the rules or your score. Motion controls can be switched off, and a colour-blind palette and reduced motion are included.

Who it is for

Puzzle fans who like physics toys and falling-sand games, and anyone looking for a calm, tactile puzzle that plays offline in short sessions.

We design, build and publish our own apps with the same engineering we put into client software.

Built in Flutter with a pure Dart sand engine: a 128 x 128 cellular automaton driven by a seeded random generator, so any run can be replayed exactly. The board is drawn from the engine's cells through a colour palette, the puzzle library is checked with a dedicated verification tool, and the game is localised into 11 languages.
