Is a popular puzzle game where you pour and sort colored liquids or items between tubes and bottles until each container holds only one uniform color.
Tap a sleeve, then another, to pour its top colour onto a matching colour or into an empty sleeve. Sort every sleeve down to a single colour to clear the puzzle, and the next one comes straight in, growing from 4 colours up to 7. One sleeve starts locked and only opens after a few moves, so plan your first pours. How many puzzles can you sort before the 9-minute clock runs out?
The goal is to move and sort the multicolored rectangles between the bottles until each bottle contains only a single color.
Testing your attention and mental abilities, you have to calculate everything in advance.
