Players need to sort piles of worms by color. The goal is to manage the board space efficiently by creating stacks of worms of the same color. When a stack of 10 or more worms of the same color is formed, those worms go underground, freeing up space on the board. The game continues endlessly, increasing in complexity as the player progresses through the levels.

Sorting: Players move worms around to create stacks of the same color.
Stacking: When a stack reaches 10 or more worms of the same color, it disappears (goes underground), liberating space on the board.
Board Space Management: Players must strategically manage the limited board space. If there isn't enough space for new worms, the player loses.
New Stacks: Each move causes a new stack of worms to appear, adding to the challenge of managing the board.
