About

Sand Unblock

Features
Read full description

Every level starts as a picture made of sand. One move later, it is a waterfall. Sand Unblock is a sliding-block puzzle with real falling sand. A drawing made of thousands of coloured grains rests on a wall of blocks. Drag the blocks out of the way, open a clear path, and the whole picture pours down through a steel funnel that sorts every grain by colour into its own glass bottle. Fill the bottles to the last grain and the level is yours. HOW IT PLAYS - Drag any block in any direction. Blocks never overlap and never leave the board. - Sand cannot pass through a block, and it never rests on one: it slides to the nearest edge and falls. - Open a full column from top to bottom and the whole picture rushes through at once. - The funnel sorts the grains by colour. One bottle per colour, filled perfectly flat. - A level is won only when 100% of the sand is bottled. 50 LEVELS, 50 PICTURES Flags, a rainbow, a heart, a rocket, a smiley, a goldfish: each level has its own sand painting, and each one ends up neatly sorted into bottles. The first levels take a single move. Later boards pack up to ten blocks and ask for a little planning, but never more than a handful of moves. It is a game for unwinding, not for getting stuck. NO STRINGS - No ads. Not one. - No purchases, nothing locked behind a paywall. - No account, no sign-in, no e-mail. - Plays offline, on the underground, on a plane, in a tunnel. Made for one hand and short sittings. Every level fits in a minute or two, and watching the sand fall is half the fun.
