Sand Unblock

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…
