# About Color Sort Puzzle

Color Sort Puzzle is an engaging and visually appealing logic game where your objective is to sort colored blocks into different tubes. The game presents a set of tubes, some partially filled with a mix of colored blocks. Your task is to meticulously move the blocks between tubes until each tube either contains blocks of a single color or is completely empty.

Based on the classic water sort puzzle concept, this HTML5 version offers a clean interface, smooth animations, and satisfying gameplay. It requires careful planning and strategic thinking to solve the puzzle efficiently. Keep track of your moves and try to complete the sort in the minimum number of steps!

## How to Play

The goal is to have each tube filled with blocks of only one color, up to the maximum capacity (typically 4 blocks).

1.  **Select a Tube:** Click or tap on a tube you want to move the top block *from*. The selected tube will be highlighted (unless a move starts immediately). The source tube must not be empty.
2.  **Select Destination:** Click or tap on another tube you want to move the block *to*.
3.  **Move Rules:** A block can only be moved if:
    *   The destination tube is empty, OR
    *   The top block in the destination tube is the *same color* as the block you are moving.
    *   The destination tube is not already full (must have space for the incoming block).
4.  **Making Moves:** If the move is valid, the top block from the source tube will animate and move to the top of the destination tube. Each successful transfer counts as one move.
5.  **Undo/Reset:** Use the "Undo" button to reverse your last move. Use the "Reset" button to start the current puzzle over from the beginning.
6.  **Winning:** The game is won when all colors are sorted correctly – every tube is either empty or contains only blocks of a single, uniform color. A "You Won" message will appear.

## Tips & Strategies

- **Plan Ahead:** Look at the arrangement and think a step or two ahead before making a move. Avoid trapping necessary blocks.
- **Utilize Empty Tubes:** Empty tubes are crucial temporary holding spots. Use them wisely to shuffle blocks around.
- **Isolate Colors Early:** Try to complete a tube with a single color as early as possible to free up space and simplify the puzzle.
- **Focus on Bottom Blocks:** Pay attention to the blocks lower down in the tubes, as they are harder to access. Plan how to uncover them.
