Casual & Brain Games Water Sort Puzzle - Color Sort

Each tube contains several layers, and only the connected block of color at the top can be poured. The receiving tube must be empty or show the same top color, with enough capacity left for the transfer. The puzzle is not simply about finding a legal pour; it is about keeping useful workspace available. Parking a single layer in an empty tube can trap it there and remove the buffer needed to uncover colors buried elsewhere. Begin with obvious same-color joins, then identify one or two colors that are close to completion. Once a tube is fully sorted, leave it intact whenever possible so completed work stays secure and the remaining board becomes easier to read. There is no timing pressure, so before every pour, check which color the source will reveal and how much space the destination will retain. When using an empty tube, favor a color that can soon receive another matching layer instead of occupying every buffer with unrelated single layers. If all tubes appear full, search for top colors that match a destination with remaining capacity. Consolidating them can reopen a usable position. When two pours are legal, prefer the move that exposes a deeply buried color or a color repeated across several tubes. In the late stage, finish one target color at a time and avoid dismantling a completed tube merely to make the visible tops look neater. A good pour solves two questions together: it joins the current color and leaves a legal destination for the layer that will be uncovered next. Following that two-step check prevents the common deadlock in which every top color is different and the empty workspace has already been consumed.
