Which type of play induces dizziness through activities like spinning and seesawing?

The correct answer is Ilinx. This type of play is characterized by activities that create a sensation of dizziness or vertigo, often through movements that involve spinning, swaying, or altering one's balance. When individuals engage in Ilinx, they experience excitement through the disorientation that these movements provoke, which can include activities such as seesawing or spinning in circles.

This form of play is distinct from the others mentioned in the question. Agon typically refers to competitive play where skill and rivalry are central. Ludus involves structured games with formal rules and objectives, and often emphasizes strategy and competition. Paidia, on the other hand, relates to spontaneous and loosely structured play that is more about free expression and creativity without strict rules. Understanding these definitions helps clarify why Ilinx fits the description of inducing dizziness through specific activities, as it focuses on the physical sensations and experiences resulting from deliberate movements that disrupt equilibrium.
