1. Setup

   - The game begins with balls of various colors randomly placed in the different compartments, but in this image, the balls are already sorted. To start a game, you would mix them up so that each compartment contains a mixture of colors.

2. Objective

   - The goal is to move the balls between compartments until each compartment contains balls of only one color.

3. Gameplay

   - Moving a Ball- You physically pick up a ball from the top of one compartment and place it in another compartment. 

   - Rules for Moving- You can only move one ball at a time.  You can only place a ball on top of another ball of the same color or in an empty compartment.

4. Winning the Game

   - You win when all compartments have balls sorted by color, similar to what is shown in the image, where each compartment is already filled with balls of a single color (pink, orange, yellow, green, and blue).

5. **Challenges**:

   - The challenge comes from strategically moving the balls to achieve the goal efficiently without getting stuck or running out of space. Mind you, you're trying to finish before your opponent.
