* A four-state game: Think of games like chess, checkers, or even a simple board game where players have four possible states (e.g., "start," "move," "attack," "win").
* A four-state system: This could refer to a physical or abstract system with four possible configurations. For example, a light switch could have four states: "off," "dim," "medium," and "bright."
* A four-state process: This could be a series of events with four distinct stages, like the four seasons or the four stages of a butterfly's life.
