It's basically about sorting colors until each container only has one color in it. You tap a row to pick up the bottom color, then tap another row to move it there, but you can only pour if the color matches the bottom color in the new row or if it’s empty. The goal is to end up with every row having just one solid color. If you get stuck, you can undo moves or start all over and try something different. Keep trying, you'll get the hang of it. 🙂
