Color Sort Puzzle

Tap a tube — selects it. The top color lifts up. Tap another tube — pours the top color into it, if the colors match or the tube is empty. Match the colors — every tube must end up with one solid color. Use undo — when you pour wrong, hit the undo button. You've got unlimited tries. Add an empty tube — sometimes you need extra space to sort. Use it when you're stuck. Controls: Tap or click. That's it. Pro Tip: Always keep an empty tube free. It's your escape hatch — without it, you're one bad pour away from a dead end. And don't pour everything into one tube just because you can. Think two moves ahead.
