The player controls the Muncher, who must move around a grid eating words that match the condition at the top of the screen, while avoiding the threatening Troggles. As the player progresses through the levels, the difficulty of the matching conditions increases, and multiple Troggles pursue the Muncher. The game was designed for first- to fifth-grade students, emphasizing vowel sounds, while teaching students grammar, phonics and reading skills in addition to introducing new words.
