In Super Munchers, the player controls a green "Muncher" character across a grid of squares containing a word expression. The objective is to consume all and only the grids containing information satisfying a specific criterion (determined by the mode of play) while also avoiding the deadly "Troggle" monsters which roamed the grid.
Eating a grid containing information that did not match the criterion of the play mode chosen or being caught by a Troggle resulted in the loss of a life.
If all grids containing information matching the criterion were eaten from the screen, the level ended and the player was presented with an amusing short scene, similar to Wile E. Coyote and Road Runner scenes, in which the Muncher foils the Troggles' plans to catch it and often destroys the Troggle in some comical manner. The game gets continually faster and harder each level.
