Stack Sorting
Stack Sorting
Stack Sorting begins with a series of disorganized cylinders placed across several vertical stacks. The primary objective is to reorganize these colorful objects so that every stack contains only cylinders of a single matching color. A first run typically starts with a selection of stacks where the top items are visible, requiring immediate decisions on where to move the first piece to clear space or begin a color group. You must click on a stack to select the topmost cylinder and then click on another stack to place it.
Movement is governed by specific logic: a cylinder can only be moved to an empty stack or on top of another cylinder that shares the exact same color. This mechanic forces you to plan several moves ahead to avoid blocking necessary colors or filling up all available empty spaces too early. The game provides different difficulty settings to adjust the complexity of the sorting process. Easy Mode offers a more relaxed environment with a generous number of stacks and a longer time limit, while Hard Mode restricts the number of available stacks, requiring much tighter organization and faster decision-making.
Success in this puzzle environment depends on your ability to manage the limited space effectively. Every move counts toward the final goal of clearing the board within the allotted time. As you progress through the levels, the arrangements become more intricate, testing your agility and spatial reasoning. The game concludes a level once every cylinder is sorted into its respective color-coded stack, rewarding players who can maintain order under the pressure of the ticking clock.

How to Play
To begin, click on any stack to pick up the cylinder at the very top. Once a cylinder is selected, click on a different stack to place it down. You can only place a cylinder into a stack that is completely empty or one where the top cylinder matches the color of the one you are currently holding.
Your goal is to continue this process until every stack on the screen contains only one color. You must keep an eye on the timer at the top of the screen, as the level must be fully sorted before the time runs out. If you run out of moves or time, you will need to restart the level.
Choose between Easy and Hard modes depending on your skill level. Easy Mode gives you more room to move pieces around, while Hard Mode limits your space, making every move critical. Plan your transfers carefully to ensure you don't accidentally block a color you need later.
