Multi-colored cylinders got mixed up, they were loaded into tall oblong flasks, without thinking about color matching. Your job in Stack Sorting is to sort to sort the cylinders by color. The container will fit four cylinders. Before starting the game, select a mode: easy or difficult. They differ in the range of colors and the number of free flasks. Each mode has eighty levels. When moving colored objects, you can only shift it to the corresponding color. The faster you complete a task, the more bonus points you will receive for not using your time in Stack Sorting.
