Players take on the task of sorting groups of objects into categories, using a grid-based system to organize and match items. Each set of objects has specific rules governing their placement, and it's up to the player to study and apply these patterns to efficiently categorize the items seen on the screen.
Upon successfully sorting an area, the grid is cleared and a new set appears with different objects to categorize. Players must adapt quickly to changing categories and rules, or risk losing points for misplaced items. The game runs directly in most major browsers with no downloads or registration required, allowing for easy access and play.
