How to play
- Drag any cap along the open tracks to an empty space. Caps cannot pass through walls or other caps.
- Read the goal markers beside the board: they show the colors each line must end with, and in which order.
- Some worlds sort each lane into a single color; others ask every column to repeat the same color order from bottom to top, shown on a marker strip at the side.
- Finish in the fewest moves for the best score. Stuck? A help credit shows the full solution step by step.
