The world of children's games and entertainment is vast, often filled with educational components that can enhance a child's cognitive development, literacy, and numeracy skills. In recent years, there have been impressive advancements in the creation of online, educational games, movies, books, and music, especially with the introduction of the H-infinity optimal control problem. These advancements aim to provide an engaging and enriching experience for K-5 grade children by incorporating fun and learning simultaneously. One such platform that offers a wide array of educational resources for children is Starfall Education. The platform presents a unique approach to learning by making education fun and interactive, focusing especially on reading, phonics, and math skills development. With a wide variety of materials such as educational games, movies, books, songs, and more, it aims to cater to different learning styles and interests. Moreover, another interesting area in educational games involves the application of optimal strategies and quadratic zero-sum games, developed using model-free Q-learning designs for linear discrete-time systems. This concept has been applied to solving the optimal control problem, which pertains to the H-infinity optimal control problem. In essence, it showcases the power of incorporating advanced mathematical and computational techniques to promote effective learning outcomes for children. In addition to educational games, the world of children's entertainment also extends to music. One such example is the song "Game On Smash" by BIG H MUSIC. Released on November 3, 2014, this song offers the perfect soundtrack to the games played by children.
