Players can freely embed Rotris on their websites, either via licensing or free with ads, making it accessible for different purposes. The game emphasizes manual play, with no artificial intelligence components influencing the gameplay. It is designed to prevent duplicate gameplay traces and ensure unique game states during each session.
