Key facts
Coverage
What does this patent actually cover?
The patent describes a game mat featuring a grid of colored circles arranged in rows and columns. A spinner determines which body part—left hand, right hand, left foot, or right foot—a player must place on a specific color. The players themselves act as the game pieces, maneuvering their bodies to occupy the designated spots without falling or touching the mat with other parts of their bodies.
The gap
What does this patent NOT cover?
- Does not cover games played on a board with physical figurines or tokens.
- Does not cover digital or video game versions of the concept.
- Does not cover the specific color arrangement or the exact number of circles on the mat.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
