Sort each color into its own tube
Pours: 0
Tap a tube to select it, then tap another tube to pour its top color into it. You can only pour onto an empty tube or one whose top color already matches — pour onto anything else and it'll bounce back with a shake.
The goal is to get every color fully separated into its own tube. It rewards planning a few moves ahead rather than pouring at random — an empty tube is a valuable resource, so it's often worth holding one back rather than filling it too early. Every puzzle is freshly generated and checked solvable before it's shown to you. Your best (fewest pours) is saved.
