Grainfall: Sand Sort Puzzle

Pour it out, sort it clean. Grainfall is a sand-sorting puzzle. Every jar starts with its colors mixed up, and you pour them from jar to jar until each one holds a single color. Tap a jar to lift it, tap another to pour. That is the whole game. REAL SAND, NOT SWAPPED COLORS Most sorting puzzles slide a block of color from one glass to another. Grainfall simulates the grains. Sand arcs out of the neck, falls, and settles where it lands, so you watch a pour happen instead of watching a color teleport. DIG DOWN LAYER BY LAYER Work down from topsoil beds to bedrock. Each episode brings new sands and new arrangements: rings, ragged columns, grids, and centerpiece vessels that hold double. No two boards are laid out alike. EVERY LEVEL HAS A SOLUTION Boards are run through a solver before they ship, so a level you are stuck on always has a way through. The difficulty curve is measured rather than guessed at. NO TIMERS. NO LIVES. Nothing counts down and nothing runs out. Undo any move. Take a week over one board if you like. PLAYS OFFLINE The whole game works with no connection at all. Your progress is saved on your device. Grainfall is free to play, with an ad between levels now and then. One Remove ads purchase clears them for good.
