Stack Sorting

Stack Sorting is a casual logic puzzle game where your objective is to organize colored discs into their own separate tubes. Played in your browser using simple mouse clicks, this HTML5 game challenges your strategic thinking.

Similar to classic sorting puzzles, you must move items one by one according to a set of rules, making it an excellent brain-teaser for players who enjoy relaxing yet stimulating challenges.

How Do You Solve the Puzzles?

The rules of Stack Sorting are straightforward but require careful planning. You interact with the game by clicking on a tube to lift its topmost disc.

You can then move that disc to another tube, but only if the target tube is empty or if its top disc is the same color.

Each tube has a limited capacity, typically holding four discs. The challenge comes from maneuvering the discs around these constraints to successfully isolate each color into its own stack.

A level is complete when every tube is either empty or filled with discs of a single color.

Strategic Planning is Key

While the concept is simple, success in Stack Sorting relies on foresight. It's easy to make a move that seems correct but ends up trapping a necessary disc at the bottom of a stack.

The best strategy often involves using an empty tube as a temporary holding area to shuffle discs around.

Before you move a piece, think a few steps ahead. Identify which colors are blocking others and plan how to free them up. Working backward from your goal can often reveal the most efficient sequence of moves to solve the puzzle.
