Scribble Sort: Water Sort

A water sort puzzle in pencil and crayon: pour the colours, sort the tubes, and colour in a sketchbook picture as you play. Scribble Sort is a colour sort game that looks like it was doodled in the back of a notebook. Every tube, star and picture is drawn in code in pencil-and-crayon style, and no two strokes are alike. HOW TO PLAY Tap a tube to pick up the colour on top, then tap another to pour. Colour only pours onto the same colour or into an empty tube. Sort every tube down to one colour and the level is solved. If you have played a water sort, liquid sort or ball sort puzzle before, you already know the rules; if not, a three-step lesson teaches them in ten seconds. COLOUR IN A PICTURE AS YOU PLAY Twenty chapters of ten levels, and each chapter draws a picture: a hot air balloon, a lighthouse, a steam train, a whale, a crystal cavern. Every level you clear colours in one more piece. Finish the chapter and the drawing is taped to your gallery wall. Twenty keepsakes to collect. 200 LEVELS, EVERY ONE VERIFIED Level 1 is three colours in a four-deep tube. Level 200 is ten colours, five deep, twelve tubes. Tube depth steps up and down between chapters so each one feels different, and every level is verified solvable. THREE STARS FOR A PERFECT SOLVE Every level has a par: the length of a genuinely optimal solution, worked out by a solver. Match it without the extra tube for three stars. A brain teaser with a real reason to replay. STUCK? Undo any number of moves. Restart any time. Free hints in every level, three apiece in chapter one and one per level after that, each pointing to a move genuinely on the way to a solution. Want another? Watch a short rewarded ad. One extra empty tube per level is there if a board is truly beyond saving; it caps that level at two stars, and it is free when no ad can load. BUILT TO BE KIND - Ads only when you ask for help.
