How to play
Choose a filled glass, then an empty glass or one with the same top color. A pour moves as many matching top layers as will fit. Fill each color into one glass; empty glasses can remain. Gentle uses three colors, steady four, challenge six, with two empty glasses. Every new board has a clearing route, but some choices can block it. Numbers identify colors. Read glass contents from top to bottom. Tab and Enter select glasses; Escape cancels selection. Undo, saved progress, reset and full screen are available. No timer. Hints search within a limit and do not promise the shortest route.
