How it plays

Every level shows a goal: the colors you need to end up with. Pour one tube into another and the colors mix, so red and blue become purple and yellow and blue become green. Plan your pours, fill the goal tubes, and try to beat the target move count for three stars.

There are 300 levels across 15 islands, each with its own tubes and music, plus a new daily puzzle every day.
