Color Tubes

Pour, sort and pop the corks! A sunny little potion lab is full of glass test tubes, and every tube holds stacked layers of glossy coloured liquid. Tap a tube to lift it, then tap another to pour: the colour on top slides out in a shiny stream, onto the same colour or into an empty tube, as long as there's room. Fill a tube with a single colour and a cork drops in with a pop and a burst of confetti. Finish the puzzle and every cork pops at once.

Every colour has its own symbol, a triangle, a star, a heart, a moon and more, so nobody needs to tell colours apart to play. Nothing ever breaks or spills, there are no timers and no lives, and undo is always free. Stuck? Take a few pours back, or add a spare empty tube. Want a nudge? The hint shows the next good pour with a ghost hand.

120 puzzles grow from two colours to nine, with deeper tubes, tight boards with a single empty tube, and mystery layers that only show their colour when they reach the top. Solve a puzzle in as few pours as possible for three stars.

Kids Mode (the turtle) is made for younger players: smaller boards, glowing hints for where a colour can go, the ghost hand after a pause, and a party every five puzzles.
