Water Sort: Color Hues

Picture a quiet shelf of glass bottles, each packed with layered liquid in the wrong places. Some colors sit trapped under others. Empty bottles wait like open doors. You pour, you pause, you pour again — until the shelf looks clean: one color per bottle, top to bottom, no leftover mix. YOUR FIRST MOVES Tap a bottle that holds the color you want to move. Tap a second bottle that can receive it. If the top shades match and room remains, the water travels. If not, nothing happens — the board is simply telling you to choose differently. THE RULE THAT MATTERS MOST Matching tops and free space decide every pour. Everything else is planning. Treat empty bottles as valuable space, not decoration. Protect them early, and hard boards become manageable. WHAT MAKES EACH BOARD FUN New layouts change the number of colors, the height of stacks, and how tight the space feels. Easy boards teach rhythm. Tougher boards ask you to hold a sequence in mind: free a path, park a color, then finish a bottle in one calm streak. COMFORT AIDS Undo a pour you regret. Shuffle when you want a fresh look at the same goal. Add a bottle when the shelf needs more air. Use them as safety nets so curiosity stays enjoyable. A SMALL DAILY HABIT Open a board during a coffee break or before bed. There is no countdown race on most stages. Just layers, choices, and the soft click of order returning. Leave the shelf tidy. One pure color at a time.
