Munchers was a series of educational/edutainment computer games produced by the Minnesota Educational Computing Consortium (MECC) for several operating systems. They were popular among American schoolchildren in the 1980s and 1990s and were the recipients of several awards. The two original games in the series were Number Munchers and Word Munchers.

In all the Munchers games, the player controlled a green "Muncher" character across a grid of squares containing a short numerical or 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 (name probably derived from troglodyte) 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.

Specific to Number Munchers are the five modes of play: Multiples, Factors, Primes, Equality, and Inequality. Players can also choose from a "challenge" mode, which randomizes these modes. In the Multiples mode, Muncher must munch all numbers which are multiples of the number given; for example, if the designated number is 3 then Muncher must eat all 6's, 9's, and 12's and avoid numbers such as 7. In Factors the muncher seeks to ingest the factors of a given number, in Primes he craves prime numbers, and in the Equality and Inequality modes the muncher devours expressions such as 2+4 which are equivalent or not equivalent (respectively) to the designated number.

Game play begins with four Muncher lives (the one currently in play, plus three others in reserve). After scoring a certain number of points, the player gains an extra life. Players lose a life if they swallow an incorrect answer.

Additionally, five different types of enemy (or "Troggle") appear throughout the game. Players lose a life if they make contact with a Troggle.

The highest known level is -127, which is equal to level 129 per wrapping.
