Hue Flow

Hue Flow is a calm, colorful water sort puzzle — the kind you can sink into for one quick round or a long, cozy session. Pour the liquid from tube to tube until every tube holds a single, pure color. Easy to pick up, gently tricky to master. Tap a tube to lift it, then tap another to pour. The top run of color flows across in a smooth, satisfying stream. Keep sorting until each tube is one clean color — that is a solved level. Made a wrong move? Undo as many times as you like, or restart the level from scratch. Every level is generated on the fly and is always solvable, so you will never hit a dead end. The difficulty rises gently: the first levels ease you in with three colors, and from there the puzzles slowly grow richer and deeper — all the way up to twelve bright, easy-to-tell-apart colors. HOW TO PLAY • Tap a filled tube — it lifts to show it is selected. • Tap another tube to pour the top color onto a matching color, or into any empty tube. • You can only pour onto the same color or into empty space, and each tube holds four units. • Sort every tube down to a single color to win, then flow straight into the next puzzle.
